Descrição: A method is described for gasifying the bottoms fraction from a coal liquefaction process. The bottoms fraction are mixed 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 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 the resulting agglomerate particles are gasified by reacting the agglomerate particles with steam in a fluidized bed.
