Abstract
The invention relates to an improved method for chemical-looping combustion of a solid hydrocarbon-containing feed using a particular configuration of the reduction zone with: a first reaction zone Roperating under dense fluidized bed conditions; a second reaction zone R; a fast separation zone Sfor separation of the unburnt solid feed particles, of fly ashes and of the oxygen-carrying material particles within a mixture coming from zone R; fumes dedusting S; a particle stream division zone D, part of the particles being directly recycled to first reaction zone R, the other part being sent to an elutriation separation zone Sin order to collect the ashes through a lineand to recycle the dense particles through a lineto first reaction zone R. The invention also relates to a chemical-looping combustion plant allowing said method to be implemented.
