Abstract
The invention relates to a method for chemical-looping combustion of a solid hydrocarbon-containing feedstock, wherein the ashes and fines are removed at the outlet of reactive oxidation zone Rby sending transported phase () coming from reactive zone R, comprising gas and solid, to a gas-solid separation zone S, then by sending solid stream () coming from gas-solid separation zone Sto a dense phase elutriation separation zone Sfluidized by a non-reducing gas () allowing the fines and the fly ashes to be separated from the oxygen-carrying material particles. Optionally, deeper separation is carried out in a dedusting zone Sarranged downstream from dense phase elutriation separation zone S The invention also relates to a chemical-looping combustion plant allowing the method according to the invention to be implemented.
