Abstract (en)

Process and apparatus for the removal of carbonaceous materials from particles containing such materials, comprising introducing said particles into the lower part of a first, riser-type reactor, into which lower part also an oxygen containing gas is introduced, the reactor being operated under entrainment conditions with a relatively high density phase in the lower part and with a relatively low density phase in the upper part at a temperature suitable to burn off carbonaceous materials, separating solids and gas at the top of the reactor, introducing the separated particles into the upper part of a second, fluidized bed-type reactor while introducing an oxygen containing gas into the lower part of the second reactor, the reactor being operated under fluidized bed conditions at a temperature suitable to burn off carbonaceous materials, removing processed particles from the lower part of the reactor, and recirculating a part of the processed particles to the lower part of the riser-type reactor.
