| 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. |
