La production de carburants liquides par thermoconversion de biomasse lignocellulosique : évaluation pour le système énergétique français futur

Abstract : Biomass will account for a growing part of world primary energy consumption and its uses should be optimized. This thesis asks to what extent second generation biofuels can contribute to such an optimization and focuses on Fischer-Tropsch liquid biofuels. In order to address this issue, two levels of approach are proposed: - at process scale, the best performances are sought among a family of about one hundred options, - on the level of the French energy system, the massive introduction of the best processes is assessed. Implementing this approach has shown how: - thermochemical biofuel processes enable to combine biomass with other less limited primary energies in order to transfer a maximum of renewable carbon from biomass into liquid fuels, but costs remain high; - optimal allocation of biomass and the part that biofuels should take in this optimization highly depend on the global evolution of the energy system and on the feasibility of CO2 storage.
