Welcome!

The research group is located at INSA Rouen Normandie. A part of the research is also done at ÅBO AKADEMI UNIVERSITY in Finland.

Our aim is to develop safe and intensified processes for the valorization of biomass.

In 2023, José Delgado successfully defended his doctoral thesis on producing gamma-valerolactone, thanks to the jury.

In 2022, our work was recognized by I&EC Research as one of the 2022 Class of Influential Researchers (2022 Class of Influential Researchers – Europe, Middle East, and Africa (acs.org))

MUST project is on the cover feature of ChemPhysChem, congratulations to Marcel Klinksiek et Sindi Baco for this work

Master's thesis

Bachelor's thesis

Our aim is to understand the reactivity of complex chemical systems: develop robust and reliable kinetic models in different thermal modes. We are using different calorimeters (RC1, C80, ARSST, etc), process intensification systems (micro-reactor, microwave irradiation) and statistical methods (Bayesian inferences, cross-validation, etc).

We have developed original approaches based on structure-reactivity and non-isothermal mode to develop robust and reliable kinetic models.

The following research activities are investigated:

• Risk assessment for the valorization of biomass processes

• Kinetic modeling of complex reaction system

• Microwave irradiation for the valorization of vegetable oil

• Microreactor for the valorization of 2nd generation biomass

• Structure-reactivity

Sebastien

In 2004, I got two master's theses: Chemical Engineering & Fine Chemistry (INSA Rouen) and Risk management of chemical hazards (University of Rouen). In 2005, I worked for nine months at Åbo Akademi University (Finland) on an industrial project (Kemira company). After this project, I started my doctoral thesis in joint degree between Åbo Akademi University and INSA Rouen on “Catalytic synthesis and decomposition of peroxycarboxylic acids” under the supervision of Prof. Tapio Salmi. In 2009, I got my Ph.D. degree with honors from both institutes and the European label. From 2009 to 2010, I continued as a junior researcher at Åbo Akademi University and focused my research on kinetic modeling on the continuous reactor.

I was appointed Assistant Professor at INSA Rouen in 2010 in the department “Risk management.” In 2015, I defended my Habillitation (University of Rouen) and became Associate-Professor. In 2015, I was also appointed Docent in chemical process technology, especially new concepts chemical in reaction engineering, modelling of chemical reactors and safety aspects at Åbo Akademi University. This position was renewed for life in 2020.

My research activities focus on developing kinetic models for complex chemical systems, the use of process intensification (microwave & microreactor) and risk analysis. These activities are devoted to biomass valorization.

Research, Innovation and Citizen&Science Workshop Rouen, 2023

From the 10th to the 12th of December, INSA Rouen organized a workshop on Research, Innovation and Citizen&Science Workshop. The objectives of the workshop were to enlarge the contacts in the field of chemical reaction engineering, focusing on high-tech innovations in reaction and separation technologies (use of milli- and microreactor technologies, 3D-printing of reactor and catalyst structures, application of ultrasound, microwave and plasma technology in reaction engineering, development of novel separation technologies, such as chromatography and membrane technology). The applications were focused mainly on valorizing components in biomass to chemicals and fuel components, and using renewable energy. The topic of science and society was also be treated as how to engage citizen in science.
We gathered 40 researchers from PhD students to full researchers and professors. Big thanks to Maria Pereira for her help.

February 2022-February 2025: Rouen’s project PROMETEE (Processes to valoRize nOrman bioMass from renEwable energies: ciTizen sciencE and process safEty)

Consortium: Aoues’s team (INSA Rouen) for the mechanical and civil engineering part, Liano’s team (Rouen university) for the citizen science part and Leveneur’s team for process safety.

Total budget : 120 k€.

Climate emergency and citizen distrust push us to re-think (re-design) the different models of environmental transition. Nowadays, interdisciplinary collaboration between engineering and social sciences is mandatory to find alternative and acceptable solutions.

Valorization of lignocellulosic biomass by renewable energy such as green hydrogen will sustain our chemical industries and contribute to the mix energy. Such processes could lead to new industrial risks that must be identified and evaluated by new methods.

Researchers from Rouen University and INSA Rouen Normandy concluded that industrial projects involving these processes must be evaluated on the innovative tetraptic Society-Industrial Risk-Environmental impact-Cost evaluation.

Lignocellulosic biomass from agricultural waste can be valorized into different chemicals, fuels and materials. These different options can affect the cost evaluation, environment or industrial risk assessment differently. Citizens will also evaluate these options by using/testing/developing different protocols.

The relationships between the structure of chemicals (reactants or products) and their reactivity (kinetics and thermodynamics) is a research area that crosslinks thermodynamics, kinetics, organic chemistry and chemical engineering. This project will investigate this research area by German and French specialists. The concept of Linear Free Energy Relationships (LFER), including the Taft equation, is a powerful structure-reactivity tool that accounts for steric, polar and resonance effects on a series of chemical reactions. Taft equation shows that there is a relationship between the structure of reactants (i.e., the substituent near to the reaction center) and their reactivities within a reaction series. It is state-of-the-art to apply this to chemical reactions (e.g. esterification), and it is claimed that the developed parameters are valid independent of the reaction conditions. However, mainly esterification and hydrolysis reactions were used in one kind of solvent, which in principle limits the general validity of the relationships. Thus, generalizing LFER concepts to vast number of solvents or solvent mixtures and even to multiphase reaction systems requires intrinsic kinetic profiles in the absence of concentration and temperature gradients, expressed in terms of thermodynamic activities. This will be developed in this project.
The redeveloped Taft-based method will be mainly applied to three chemical reaction systems that involve lignocellulosic-derived platform molecules: 1) glucose solvolysis to levulinate ester using different alcohol solvents, 2) esterification-hydrolysis of levulinic acid-levulinate ester and
3) hydrogenation of levulinic acid or levulinate ester to gamma-valerolactone by H2 and solid catalyst. We will vary the reactants for these systems, i.e., different alcohols for 1) and 2), and different levulinate esters for 3). System 2) will prove the validity of the LFER concept to enzyme catalysis. The goal is to use the redeveloped method to study and predict the -R substituent effect in the reactant and the solvent effect on kinetic profiles.

Reaching the goal requires different research expertise. The use of microfluidic technologies will allow performing kinetic experiments avoiding transport limitations. Activities of the reactants and products will be predicted based on the experimental kinetic profiles and the equation of state ‘ePC-SAFT’. This will ultimately allow predicting reaction properties (standard enthalpies, standard Gibbs energies) as well as intrinsic activity-based reaction kinetic constants. Furthermore, ePC SAFT will be used to predict the required phase behavior of the reaction systems (e.g. H2 solubility in reaction medium); all predictions (phase behavior and reaction characteristics) will be validated by experiments.
The association of both methods –LFER & ePC-SAFT– will mean a significant new understanding and a new dimension in designing chemical syntheses.

Scientific presentation

Fossil raw materials are the most used feedstock in the energy sector and in the chemical industry. For instance, 90% of organic chemicals are synthesized from petroleum or natural gas. Public authorities, industries and academies put a considerable effort into developing green and sustainable processes.

The use of vegetable oils, as renewable feedstock, for the production of chemicals or biofuels is a good illustration of this effort. The worldwide production of vegetable oil is increasing since 1975. The part of production for industrial use also increases and not only for biodiesel. Vegetable oils can be considered as platform molecules.

Epoxidation of vegetable oils is one of the most important ways of functionalization. Epoxidized vegetable oils can be used as starting materials for the production of NIPU (Non-Isocyanate Polyurethanes) or as biolubricants, stabilizers or stabilizers for polymers. Worldwide production of polyurethane has increased these last years, making it among the 6 polymers the most produced, due to its versatile properties.

Production of NIPU from vegetable requires three different reaction steps: epoxidation of vegetable oils; carbonation of epoxidized vegetable oils by the reaction between epoxidized group and carbon dioxide and production of NIPU by aminolysis reaction, i.e., reaction between carbonated group and a diamine. The difficulties in putting this process at the industrial scale are the lack of knowledge in kinetics, thermodynamics and fluid mechanics.

Despite all the different research, one can notice that some important data are still missing to promote the industrial scale and the safety of this process. One of the first points is to propose a complete kinetic model for the production of epoxidized vegetable oils by taking into account the evolution of the viscosity. This first stage is essential to optimize the production of this intermediate and to prevent the thermal runaway risk. The second step is to develop an advanced kinetic model for the 2 other steps: carbonation and aminolysis.

With the detailed modelling of the unknown reaction system based on assumed reaction mechanism and kinetic expressions, a lot of new information can be collected to support the design of the reactor unit. The dynamical behaviour of the unknown reaction system can be predicted with the identified reaction rate expressions, which can consider the temperature dependencies next to the concentration. If we use both the kinetic and the hydrodynamic information obtained from the different models, then a detailed model can be developed which can be used to predict the behaviour of a device after validated against measurements.

The hydrodynamic behavior of the device can be so complex, that a Computational Fluid Dynamics (CFD) model is necessary to be developed to reach the desired level of model accuracy. In process engineering practice CFD models can support the process optimization tasks. With the up-to-date computers the momentum, heat and component mass balances can be solved together in time and in multiple geometric dimensions, due to the available significant computation capacity.

Scientific presentation

For the valorization of biomass, the tendency is to work on the production of platform molecules. Furthermore, lignocellulosic biomass should be privileged because of its non-competition with food. There are different potential platform molecules issued from lignocellulosic biomass like sorbitol, furfural, hydroxymethylfurfural (HMF), levulinic acid, lignin monomer, ethanol, butanol or lactic acid. Levulinic acid is of particular interest, and has been identified as one of the twelve promising building blocks by the US department of energy.

The design and scale-up of new processes and technologies using biomass feedstock might involve emerging risks according to the International Risk Governance Council: issues that are perceived to be potentially significant, but they may not be fully understood and assessed and therefore correctly managed, e.g. bio-hazards, thermal risk and dust explosion.

On one hand, processes using biomass are usually perceived as thermally and/or toxicology safer or even completely harmless with respect to other conventional chemical processes. On the other hand, using biomass as a raw material entails hazardous materials and severe process conditions such as acid hydrolysis, high pressures, and temperatures and a risk assessment should be performed. Society could accept such processes based on biomass, i.e., biorefinery, because it can promote new jobs, consume local biomass feedstock and waste, diminish the dependency towards fossil feedstock and use ecofriendly raw materials. Thus, to preserve the development of such sustainable industries, and its image towards public opinion, a risk assessment should be carried out [1].

To summarize, one needs to use harsh operation conditions (high temperature and pressure) to fractionate the lignocellulosic biomass and to depolymerize cellulose, hemicellulose and lignin to platform molecules. During these different steps, there are some exothermic reactions, which could lead to thermal runaway in case of temperature loss. The use of microreactor could be beneficial to perform such processes.

The microscale reactor is a device whose operation depends on precisely controlled design features with characteristic dimensions from submillimeter to submicrometer. The fundamental advantages of microstructured over the conventional reactors can be classified due to the decrease in physical size and increase in number of units [2]. Small reactor size (at least one dimension below 1 mm, typically in the range 50–500 mm) and high surface-tovolume ratio (typically 10.000–50.000 m²/m³) together with a continuous operation mode resulting in, for example, improved mixing and energy efficiency, heat management, scalability, and safety and lower waste production, are strategic advantages of microfluidic systems over large-scale reactors [3].

The intensification and optimization of existing chemical processes with better selectivity, highly efficient heat and mass transport, products quality, process safety, as well as the development of new and environmentally friendly technologies are feasible with the microreactor technology. Increasing research efforts and the growing industrial interest in using microscale technology for continuous-flow organic synthesis and for various continuous-flow separations shed new light on basic process development and sets a new paradigm for chemical production. Point-of-use generation of toxic, explosive, and hazardous chemicals in situ within integrated microfluidic systems improves safety, health, and environment issues and allows multiple reactions and separations [3].

There is a need to develop intensified process units for the valorization of 2^nd generation biomass, which could ensure the thermal stability of the system. Such work is complex and a single research group could not do it. For this reason, LSPC (Normandie Université INSA-Université Rouen) with the Process Engineering Research Group (University of Ljubljana) have decided to join their efforts.

For this project, the use of microreactor for the hydrolysis of cellulose and the production of γ-valerolactone from the hydrogenation of levulinic acid will be studied. Indeed, these two systems are exothermic and require high reaction temperature and pressure.

At LSPC, we are working on the fractionation of lignocellulosic biomass (doctoral thesis of Xiaoshia LU), on the safe production of γ-valerolactone from the hydrogenation of levulinic acid (doctoral thesis of Yanjun WANG), on the production of monomers from biomass and CO2 (doctoral thesis of Wander Perez) and on the thermal stability of continuous reactor (doctoral thesis of Elizabeth Garcia Hernandez).

Scientific presentation

Due to fossil depletion, environmental issues, global warming and energy dependence from some fossil-energy-exporting countries, the development of process based on biomass raw materials tends to increase.

The increase in the number and potentiality of bioenergy facilities associated to the scale-up to industrial production, as well as to the industrial implementation of innovative processes and technologies, is generating a ‘major accident’ hazard. According to Seveso Directive, a major accident is defined as an occurrence such as a major emission, fire, or explosion resulting from uncontrolled developments in the course of the operation leading to serious danger to human health and/or the environment, immediate or delayed, inside or outside the establishment, and involving one or more dangerous substances.

The scale-up of such processes could entails an “emerging risk” (according to the definition of the International Risk Governance Council), i.e. issues are perceived to be potentially significant but they may not be fully understood and assessed, thus not allowing risk management options to be developed with confidence.

Processes using biomass raw materials are usually perceived as safer or even completely harmless than the ones using petroleum-derived products. However, these raw materials require several treatments (acid hydrolysis, high pressure and temperature). In fact, in the last decade, there have been several accidents involving bioenergy production and feedstock supply chain that raised concern on the safety of such technologies. A recent analysis of major accidents in bioenergy industry showed that their number is growing faster than bioenergy production. A comparison with the number of accidents in oil refining activities shows that the increasing trend is specific of bioenergy. In particular, many of the accident analysed entailed considerable environmental losses, which poses the question of the management of response time during such emergencies. In fact, in the perspective of a safe and sustainable exploitation of renewable resources, this is to be considered an early warning and suggest the importance of risk awareness and safety culture in bioenergy production. It is worth noticing that limited safety requirements exist in EU, since most of the production plants are medium to small scale and thus are not included in the application of Seveso Directives.

In this perspective, risk assessment is a fundamental step (according to ISO 31000:2009) in emergency response, in order to (1) contain or mitigate the effects of the event, and (2) restore order and re-establishing normality in the immediate aftermath of the event. Emergency response cannot be random, but has to be prepared in advance, so that, when an unexpected event occurs, it will be carried out in a well-timed, coordinate and effective manner. The phases of the preparedness are:

• plan, i.e. establishing a-priori how to respond in the best way to an unexpected event;

• organize / equip, that is providing human and financial resources, and technical equipment necessary for responding to an emergency;

• train, that is giving them confidence in the emergency procedures, improving the ability of each person to carry them out his role successfully in the procedure;

• exercise, i.e. simulating an emergency situation, with the purpose of testing procedures and of giving people practice in carrying out them, in order to validate the emergency plan;

• evaluate / improve, that means objectively reviewing the exercise looking for gaps and shortfalls in the emergency plan, so to identify opportunities for improvement.

In order to carry out emergency response planning, the first necessary step is the definition of emergency scenarios resulting from the risk assessment of the system. This means that, as stated by the ISO 31000:2009 standard, the risk of each event has to be expressed in terms of a combination of its consequences and the associated likelihood of occurrence.

In this framework, the present proposal answers to the societal challenges “Secure, clean and efficient energy” defined by the European program H2020, because society could accept bioenergy production processes as they can promote new jobs, consume local biomass feedstocks and waste, diminish the dependency towards fossil feedstocks and use ecofriendly raw materials. Thus, to improve the development of this sustainable industrial sector, research is needed.

Several groups are working on issues related to biomass valorization such as the choice of the biomass to be used in order to reduce the environmental impact on the soil or process simulations aimed at economic analysis of the systems and at improving energy integration. Literature concerning these issues is quite vast. However, safety aspects are rarely studied.

Thus, the main goal of the present proposal is to assess the risk of second-generation biomass valorization processes in order to provide better inputs to emergency planning, which in turn will improve response time in the case of emergencies that could lead to human and environmental losses. In particular, a process based on second-generation biomass (that produced from lignocellulose biomass, e.g. forest residues, crops residues or herbaceous and woody energy crops) will be considered. The development of processes using lignocellulosic biomass materials (LCBM) is increasing because of its non-competition with food crops. Several pilot or pre-industrial units have been built and more will be operating soon.

More in details, the process of interest will be the production of levulinic acid (LA). It is worth mentioning that LA has been identified as one of the 12 top promising building blocks by the US Department of Energy, and it can be seen as a platform molecule for the production of bio-chemicals/-fuels.

Different processes have been developed so far for the production of LA from LCBM. In particular, we will focus our analysis on the Biofine Process, that could allow a further upgrading of LA to gamma-valerolactone (GVL) via hydrogenation (hydrogen is produced in situ from the decomposition of formic acid). GVL is, in turn, a key platform molecule for the production of bio-chemicals/-fuels. To the best of our knowledge, this process is still at the pilot scale up. Our scope is to assess the risk of this existing industrial process; furthermore a unit for the production of GVL from the hydrogenation of LA will be included in the analysis.

Risk assessment and its quantification (necessary for the definition of emergency response time) of such a complex processes cannot be performed by a single research group but by a consortium. For this reason, LSPC (Normandie Université INSA-Université Rouen) with the support GSCP (EFL, Switzerland), and DICAM (University of Bologna, Italy) have decided to work together on this topic.

Recent studies showed that potential consequences on different environmental media due to the release of substances environmental hazardous may be greatly reduced if the emergency response scheduling is prompt and effective. This is especially true when dealing with liquid spills into the soil, which may eventually reach also the capillary fringe and then the water table.

This is mainly due to different dynamics and characteristic times for the release and the for the fate and transport phenomena of the spilled chemical; being the first relatively fast and the latter quite slow, if compared with typical release rates.

Thus, beyond a quick intervention for stopping the release is clearly extremely important, it can be very important as well also the first intervention time (i.e. the elapsed time from the beginning of the release to the first on-site emergency intervention). Moreover, a second intervention is often necessary in order to finally remediate the polluted soil and/or groundwater and also this second step if promptly carried on becomes cheaper and more effective.

The scheduling of these actions depends on several factors. First an estimation of potential environmental consequences is required on the basis of a risk analysis for the facility that can cause the environmental damage. From the analysis both expected consequences and frequencies of Loss of Containment events may be derived, thus properly addressing resources to most relevant/most frequent scenarios. Another important factor that affects emergency response to environmental hazards is the selection of proper remediation action/technology both for the first emergency intervention and for the final remediation action. A proper selection should be based at least on the following items:

• Transport properties of the substance through the soil and into groundwater

• Terrain morphology and soil texture

• Availability (or distance) of emergency intervention units and/or of off-site remediation plants

An environmental emergency response that is planned on the aforementioned elements could largely mitigate consequences for the environment due to accidental spills of chemicals, thus reducing also the indirectly induced health risk for individuals.
