ABSTRACT:
In a process and apparatus for the production of gas containing hydrogen and carbon monoxide from a solid fuel in a fluidized bed, the solid particles contained in the product gas are separated off in a cyclone separator and recycled to the fluidized bed by way of a recycling conduit. The recycling conduit is provided with injection nozzles for introducing gas flows into the recycling conduit in a pulse-like manner in order to loosen up the particles therein. The gas flows may be introduced into the recycling conduit in displaced relationship in respect of time in such a way that, of two adjacent injection locations, gas is injected through the injection location which is arranged at a greater spacing from the reactor at a later time than at the injection location which is closer to the reactor.
