Bio

Christian JALLUT est diplômé de l’INSA de Lyon en 1981 (département de Génie Energétique, spécialité Génie Chimique). Il a obtenu un DEA en « Automatique et Informatique Industrielles » en 1982. Son travail de thèse soutenu en 1984 portait sur la modélisation et le contrôle d’une colonne à distiller couplée à une pompe à chaleur.
Entre 1984 et 1987, il a occupé un emploi d’Assistant à l’INSA de Lyon, au département de Génie Energétique. Il a été impliqué durant cette période dans un projet concernant l’utilisation de l’énergie solaire dans les bâtiments industriels.

A partir de 1987, comme Maître de Conférence à l’Université Lyon 1, son activité s’est à nouveau orientée vers le Génie des Procédés et l’Automatique. Il a participé à la création du LAGEP. Il s’est intéressé durant cette période à la modélisation et au contrôle des procédés discontinus et à la calorimétrie de réaction.

Entre 1991 et 1994, il a occupé un emploi de Professeur des Universités en Génie des Procédés à l’INP de Grenoble – ENSEEG (Ecole Nationale Supérieure d’Electrochimie et d’Electrométallurgie de Grenoble). Il a développé des recherches dans le domaine des méthodes inverses pour la détermination expérimentale des propriétés de transport de chaleur et de matière au sein du GRETh (Groupement de Recherche sur les Echangeurs Thermiques), un laboratoire du CEA de Grenoble. Il s’est aussi intéressé aux problèmes d’encrassement particulaire dans les échangeurs de chaleur.

Depuis 1994, il est Professeur de Génie de Procédés à l’Université Lyon 1 et chercheur au LAGEP. Il est impliqué dans des projets de recherche sur la modélisation dynamique pour la détermination de propriétés de transport et le contrôle des procédés :
• Modélisation dynamique des procédés d’adsorption et des colonnes de chromatographie. Chromatographie inverse : applications et développements théoriques basés sur les concepts d’identifiabilité structurale ;
• Modélisation dynamique des procédés d’extrusion réactive pour la commande ;
• Modélisation dynamique des machines thermiques et des stocks associés pour la commande.

D’un point de vue plus théorique, il est impliqué dans des recherches concernant l’application des concepts de la thermodynamique d’équilibre et des phénomènes irréversibles à la modélisation structurée (approche par les graphes de liaison ou « Bond graph ») et à la commande des procédés (commande des réacteurs chimiques et études de stabilité globale).

Christian JALLUT enseigne la Thermodynamique, la Modélisation dynamique des procédés et les Phénomènes de transport à l’Université Lyon 1 (licence, master, faculté de Pharmacie), à l’ESCPE (Ecole Supérieure de Chimie Physique Electronique de Lyon) et à l’Ecole Polytechnique Universitaire de l’Université Lyon 1.

Prof. Christian JALLUT was graduated in 1981 from the “INSA de Lyon” Polytechnic Institute in Energy and Chemical Engineering. He also got a Master degree in Automatic Control. He worked for his PhD thesis on modelling and control of a distillation column coupled with a heat pump.
Between 1984 and 1987, he was involved at “INSA de Lyon” in a project concerning the use of solar energy in industrial buildings. Between 1987 and 1991, his activity was oriented toward chemical engineering and process control at Lyon University. He was particularly involved in batch process modeling and control and reaction calorimetry.

Between 1991 and 1994, he got a position of full Professor of Chemical Engineering at the “Institut National Polytechnique de Grenoble” in the Electrochemistry and material science department (“Ecole Nationale Supérieure d’Electrochimie et d’Electrométallurgie de Grenoble”). He made researches on the use of transient state techniques for measuring heat and mass transport parameters as well as on liquid phase particulate fouling in heat exchangers in collaboration with the French Atomic Energy Agency (CEA, “Commissariat à l’Energie Atomique”).

He is now full Professor of Chemical Engineering at Lyon University since 1994 and is a member of the “Laboratoire d’Automatique et de Génie des Procédés” (Process Control and Chemical Engineering Lab) of this university. He is involved in transient state modeling of processes for properties determinations and control:
• Dynamic modelling of adsorption processes and chromatographic columns. Inverse chromatography: application and theoretical developements based on structural identifiability properties ;
• Dynamic modelling of reactive extrusion processes for control ;
• Dynamic modelling of heat pumps and associated storages for control.

From the theoretical point of view, Christian JALLUT is involved in researches based on equilibrium and irreversible thermodynamics applied to Bond graph structural processes modelling and control (chemical reactors stability studies and control).

Prof. Christian JALLUT gives lectures in Thermodynamics, Dynamic modeling of processes and Transport Phenomena.

Role of Structure and Chemistry in Controlling Separations of CO2/CH4 and CO2/CH4/CO Mixtures over Honeycomb MOFs with Coordinatively Unsaturated Metal Sites

A systematic study of the effect of coordinatively unsaturated sites (cus) in the separation of CO2/CH4 and CO/CO2/CH4 mixtures on CPO-27-M (M = Ni, Co and Zn) and STA-12-Ni metal-organic frameworks was carried out using gravimetric and breakthrough experiments. The separation selectivity and the working capacity of these structures were evaluated as important performance indicators for CO2 separations by PSA. The results demonstrate a remarkable influence of coordinatively unsaturated sites on the selectivity and the working capacity. Particularly, the high affinity of CPO-27-Ni and CPO-27-Co for CO2 leads to a low working capacity for CO2 (because regeneration of the adsorbents is difficult), but a high CO2/CH4 selectivity. With a ternary CO/CO2/CH4 feed mixture, CPO-27-Ni and Co prefer the adsorption of CO over CO2, due to the strong specific interaction of CO with cus. Surprisingly, STA-12-Ni does not exhibit the same behavior: it is selective for the adsorption of CO2 in a ternary mixture, just like CPO-27-Zn. Among the four MOFs tested in this study, CPO-27-Zn presents the best compromise between the working capacity and the CO2/CH4 and CO2/CO selectivities. The results are discussed in terms of the coordination chemistry of the coordinatively unsaturated metal sites, their acid-base properties and their accessibility.

Dynamic modeling of the reactive twin-screw co-rotating extrusion process: experimental validation by using inlet glass fibers injection response and application to polymers degassing

In this Article is described an original dynamic model of a reactive corotating twin-screw extrusion (TSE) process operated by the Rhodia Co. for the Nylon-66 degassing finishing step. To validate the model, dynamic experiments have been performed on a small-scale pilot plant. These experiments consist of a temporary injection of glass fibers at the inlet of the extruder after it has reached a given operating point. The outlet glass fibers mass fraction time variation is then measured. This experiment does not lead to the RTD measurement. As a matter of fact, due to the high quantity of glass fibers that is introduced, the behavior of the flow through the extruder is perturbed so that the glass fibers cannot be considered as an inert tracer. The dynamic model that we have published elsewhere (Choulak et al. Ind. Eng. Chem. Res.2004, 43, 7373–7382) is adapted to take into account this nonlinear behavior of the extruder with respect to the glass fibers injection and is favorably compared to experimental results. The description of the degassing operation is also included in the model. The model allows simulations of the complete dynamic behavior of the process. When the steady state is reached, the good position of the degassing vent with respect to the partially and fully filled zones positions can also be checked, thus illustrating the way the model can be used for design purposes.

A multiscale physical model for the transient analysis of PEM water electrolyzer anodes

Polymer electrolyte membrane water electrolyzers (PEMWEs) are electrochemical devices that can be used for the production of hydrogen. In a PEMWE the anode is the most complex electrode to study due to the high overpotential of the oxygen evolution reaction (OER), not widely understood. A physical bottom-up multi-scale transient model describing the operation of a PEMWE anode is proposed here. This model includes a detailed description of the elementary OER kinetics in the anode, a description of the non-equilibrium behavior of the nanoscale catalyst–electrolyte interface, and a microstructural-resolved description of the transport of charges and O2 at the micro and mesoscales along the whole anode. The impact of different catalyst materials on the performance of the PEMWE anode, and a study of sensitivity to the operation conditions are evaluated from numerical simulations and the results are discussed in comparison with experimental data.
