Method and apparatus for gasifying solid carbonaceous material

摘要

Method and apparatus for gasifying of a solid carbonaceous material in a fluidized bed reactor in which the solid particles entrained by the gases being removed from the upper part of the reactor are separated and returned to the lower part of the reactor. oxygenous gas is supplied into the lower part of the reactor and the non-reacted carbonaceous material separated from the gases is oxidized in the lower part of the reactor. The carbonaceous material is introduced above the oxidizing zone into a zone substantially free of oxygen and the carbonaceous material is pyrolyzed and reduced by means of the hot gases and particles rising from the lower part of the reactor.
