[Thermoconversion of carbonaceous materials to produce synthetic fuels: the biomass case].

In the present energy context, there is a growing interest for the fuel production from biomass. While the first generation of biofuels has shown its limits, a second generation appears that is based on the valorisation of the unused resources of lignocellulosic biomass. This could significantly increase the biofuels potential in France. Up to 40 % of the total needs of transport fuel could be covered. Among the processes under development, the Biomass to Liquid (BtL) process seems as an interesting route, able to be shortly implemented at an industrial scale. This process consists in producing liquid fuel (such as Diesel Fischer-Trospch) through a synthetic gas obtained by biomass gasification However R&D work is still needed to solve the remaining key issues of the process. These studies are performed in several laboratories in Europe, especially in Germany and in the Nordic countries, and also more recently in France, notably in the Commissariat à l'Energie Atomique.
