Abstract: Various aspects provide for a multistage fluidized bed reactor, particularly comprising a volatilization stage and a combustion stage. The gas phases above the bed solids in the respective stages are separated by a wall. An opening (e.g., in the wall) provides for transport of the bed solids from the volatilization stage to the combustion stage. Active control of the gas pressure in the two stages may be used to control residence time. Various aspects provide for a fuel stream processing system having a pretreatment reactor, a combustion reactor, and optionally a condensation reactor. The condensation reactor receives a volatiles stream volatilized by the volatilization reactor. The combustion reactor receives a char stream resulting from the removal of the volatiles by the volatilization reactor.

Abstract: The invention relates to a method for chemical looping (CLC) oxidation-reduction combustion of liquid hydrocarbon feedstocks carried out in a fluidized bed, wherein liquid hydrocarbon feedstock (2) is partly vaporized on contact with a hot solid (1) in form of particles so as to form a partly vaporized liquid feedstock and to form coke on said solid (1), prior to contacting partly vaporized liquid feedstock (19) with a redox active mass in form of particles (12) so as to achieve combustion of partly vaporized liquid feed (19). Hot solid particles (1) used to carry the coke can notably form a second fluidized-bed particle circulation loop, the first one being the circulation loop of the oxygen-carrying redox active mass (12) circulating between the oxidation and combustion reactors, thus allowing coke-carrying particles (1) to be recycled to the process.
