Abstract: The invention relates to a device for the treatment of a feedstock, comprising a furnace (301) with an enclosure comprising an inlet (316) and an outlet (304) for the feedstock and an inlet (317) and an outlet (318) for a gas. The device comprises a feedstock recovery system (306) comprising a recovery line (305) connected to the enclosure at the feedstock outlet (304) and comprising a sampling and/or analysis means (319). It comprises two lines in parallel downstream of the sampling and/or analysis means (319), one of the lines being a line leading to a storage tank (308) and another line being a line leading to a port (303) for reintroducing the feedstock into the furnace (301). The invention also relates to a drying or torrefaction process and to an installation for producing hydrocarbons using the drying or torrefaction device.

Abstract: The present invention relates to a process for converting a feedstock comprising at least one biomass fraction into hydrocarbons, said process comprising a step a) of pretreating the feedstock, a step b) of electrolysis of water into oxygen and hydrogen allowing the production of a stream of hydrogen and of a stream of oxygen, in which the water is at least partly obtained from a Fischer-Tropsch synthesis step e), a step c) of gasification of the feedstock pretreated in step a), in the presence of all or part of the oxygen stream obtained from the water electrolysis step b) so as to obtain a gaseous effluent comprising a synthesis gas, an optional step d) of conditioning the gaseous effluent comprising a synthesis gas obtained from step c) and a step e) of Fischer-Tropsch synthesis of the gaseous effluent obtained from step c) or optionally from step d) in the presence of all or part of the hydrogen obtained from the water electrolysis step b) so as to produce a stream comprising synthetic liquid hydrocarbons
