Abstract
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.
