Solid carbonaceous material, such as coal, is pyrolyzed in a pyrolysis reaction zone (18) in the presence of a particulate source of heat and gaseous hydrogen to yield a particulate carbon- containing residue of pyrolysis and volatilized hydrocarbons while the volatilized hydrocarbons are simultaneously hydrogenated. The particulate source of heat is formed by oxidizing carbon in the particulate residue to heat the particles and the hydrogen for hydrogenation is obtained by reacting a portion of the particulate residue with steam. The oxidation and hydrogen production may be carried out separately in an oxidation zone (12) and a conversion zone (14) or may alternatively be carried out together in a combined oxidation-conversion zone (13). Steam and/or carbon dioxide can be introduced into the pyrolysis reaction zone to react with carbon-containing residue and increase the yield of liquid hydrocarbon values. <IMAGE> |
