RECOVERY OF CATALYSTS FROM THE HYDROGENATION OF COAL W. C. Schroeder ABSTRACT OF THE INVENTION Coal hydrogenation catalyst is recovered from coal hydrogenation residues containing carbonaceous matter, coal ash and catalyst by contacting such residues with oxygen and steam under conditions to provide H2 and CO containing gases and fused ash which contains catalyst, contacting the fused ash with a reactant which will react with the catalyst to form a catalyst compound which is volatile at the temperature of the fused ash and withdrawing vaporized catalyst compound from the fused ash. The vaporized catalyst may be condensed and dissolved in a solvent liquid to form a solution of catalyst for application to coal to be hydrogenated.
