ABSTRACT:
A process for producing gas containing CO and H.sub.2 from pulverulent to coarse-grained coal in a coal gasifier in which a fluidized bed is produced, and to which are supplied coal, oxygen and/or one or more oxygen-containing gases. The coal is supplied in counter-current to the gas removed from the fluidized bed. Thus, the coal is dried, degassed and preheated before it enters the fluidized bed. The upper limit of the particle size of the coal is between about 10 mm and 40 mm, and is determined by the volatile matter content of the coal.
