Catalysis and reaction kinetics

The dehydration of bio-based alcohols to form alkenes is a key reaction to obtain major chemical intermediates from biomass. It is efficiently catalyzed by zeolites presenting Brønsted acid sites and a crucial challenge is the control of its selectivity...

The olefin oligomerization reaction provides access to a broad range of key compounds in the fuel, petrochemical and fine chemistry sectors...

​​​​​​​The vast majority of oil refineries are equipped with a catalytic reforming unit that fulfils three main functions: production of high-octane oil cuts for gasoline production (known as reformates), production of aromatic-rich cuts containing fewer than 10 carbon atoms, used in the chemicals industry, and generation of dihydrogen, primarily used in hydrotreatment and hydrocracking units...

Driven by the global challenge of switching to a more sustainable economic and energy model, IFPEN has been studying for a number of years biosourced products with high added value and working to develop processes for biomass recovery, as an alternative to conventional petrochemistry.

Although the climate crisis makes the reduction of CO2 emissions a matter of urgency, some industries will have difficulty in avoiding them, such as cement plants (where the core process is currently based on the calcination of CaCO3) or refineries, which are currently highly energy-intensive. Hence the huge potential interest in procedures that could capture the CO2 released directly from the plant (...) then recover it at a fraction of the energy cost...

Faced with the current climate challenges, alternative fuels are attracting a growing interest for the mobility of the future. Of the various possible alternatives, hydrocarbons could be synthesised via a well-known process: the Fischer-Tropsch (FT) process, based on Syngas (CO and H2) produced, in particular, by biomass gasification. (...) However, the deactivation of FT catalysts is a major issue that directly impacts the costs of the process. (...) To identify these mechanisms, a multiple-stage methodology was implemented as part of a doctoral thesis...
