    摘要: 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.

    摘要: The invention relates to an integrated method for gasification and indirect combustion of a solid hydrocarbon feedstock in a chemical loop, comprising: contacting solid hydrocarbon feedstock (1) with water (2) in a gasification reaction zone RG in order to discharge ashes (9) and to produce a gaseous effluent (3) comprising syngas and water, supplying reduction reaction zone RR of a redox chemical loop with at least part of gaseous effluent (3) produced in the gasification reaction zone in order to produce a CO2 and H2O-concentrated gaseous effluent (4), reoxidizing the oxygen-carrying solid particles from reduction reaction zone RR of the chemical loop in oxidation reaction zone RO by means of an oxidizing gas (6) and discharging fumes (7). The invention also relates to a plant allowing said integrated method to be implemented.
