Malek, J M

In this process the products of the dissolution-hydrogenation of coal or the like material in a hydrocarbon rich solvent are subjected in their slurryform fraction to an asphaltenes decomposing action of an alkali, like caustic soda or, being admixed after the gasiform fraction of the hydrogenation products has been taken off the slurryform fraction of the hydrogenation products now including the admixed alkali is subjected to a rehydrogenation by a hydrogen rich gas which after its rehydrogenating use is preferably applied, as source of hydrogen, to said dissolution-hydrogenation of coal. Optionally the admixed alkali includes minor amounts of a carboxylic acid salt of calcium.
