Biography: Doan PHAM MINH received his PhD degree in chemistry at the University Lyon 1, France in 2006. He is currently Deputy Director of the RAPSODEE research center, UMR CNRS 5302 at IMT Mines Albi - an engineering school in France. His research is focussed on the design of new performing catalysts for application in carbon dioxide valorization, syngas, hydrogen, biomethane, biofuels production, as well as on the development of refractory ceramics for thermal energy storage. He is supervisor and co-supervisor of 22 PhD students, 11 post-doc and 23 internships. He is co-author of 93 articles, 9 book chapters, 3 patents, and he is editting two books in the field of heterogeneous catalysis (publication in 2022).

 

Speech Title"Catalytic conversion of carbon dioxide into liquid fuels: A possible solution to reduce greenhouse gas emissions"

Abstract-Carbon dioxide (CO2) emissions mainly come from combustion of fossil fuels. Therefore, CO2 capture and utilisation (CCU) plays crucial role to limit greenhouse gas emissions to the atmosphere. This can be possible by the conversion of CO2 to valuable products, including C1 products (CO, CH4, CH3OH etc.) and C2+ products. To-date, CO2 hydrogenation is usually performed in two consecutive steps: the reverse water-gas-shift reaction (RWGS) converting CO2 to CO; followed by the conventional Fischer Tropsch synthesis (FTS) converting CO to C1 or C2+. In fact, RWGS is slightly endothermic (∆rH°298 = 41 kJ/mol) and thermodynamically favoured at high temperatures (above 500 °C), while FTS is strongly exothermic and favoured at moderate temperatures (200-250 °C). Combining both steps of RWGS and FTS in a unique reactor is meaningful from the economical point of view, but faces problems related to the control of reaction temperature for these two hydrogenation steps. Moderate temperatures (200-250 °C) favour the exothermic FTS and drive the selectivity towards C2+ products, but also detriment endothermic RWGS reaction by provoking a series of competitive reactions (e.g. methanation) that can strongly affect the selectivity of the global process. Thus, the main objective of this work is to design a convenient catalyst system which allows performing both steps of CO2 hydrogenation in to C2+ in a fixed-bed reactor. The latest results obtained by our research team at the RAPSODEE research center, LCC and LPCNO laboratories, France, will be presented.
