ABSTRACT:
A method for gasifying the bottoms fraction from a coal liquefaction process by mixing the bottoms fraction with at least one finely-divided calcium compound selected from the group consisting of calcium oxide, calcium carbonate and calcium hydroxide with the calcium compound being of a size consist no larger than about -200 Tyler mesh and present in an amount sufficient to produce agglomerate particles upon mixing with the bottoms fraction and thereafter gasifying the resulting agglomerate particles by reacting the agglomerate particles with steam in a fluidized bed.
