摘要：
The invention relates to a method for the chemical looping combustion of a solid hydrocarbon feedstock, in which the ash and fines leaving the reactive oxidation zone (R1) are removed, with the entrained phase (5) originating from the reactive zone (R1) and comprising gas and solid being sent to a gas-solid separation zone (S2), and the solid flow (7) originating from the gas-solid separation zone (S2) being sent to a dense-phase elutriation separation zone (S3) fluidised by a non-reducing gas (8) that can be used to separate the fines and fly ash from the particles of oxygen-carrying material. Optionally, enhanced separation is performed in a dust removal zone (S5) located downstream of the dense-phase elutriation separation zone (S3). The invention also relates to a chemical looping combustion facility that can be used to perform the aforementioned method.
