ABSTRACT:
Feed coal particles are mixed with fine particles of devolatilized carbonaceous material having an average particle diameter less than about 25% of that of the coal and then injected into a high temperature fluidized bed gasification zone. The devolatilized material adheres to the coal particles as they soften and forms a nonsticky coating which hinders the formation of large coal agglomerates. During the gasification process the adhering particles are retained in the bed and at least partially gasified, resulting in better carbon utilization than might otherwise be obtained.
