Pretreatment of subbituminous coal with an appropriately formulated mix of carbon monoxide and water, in presence of bitumen or heavy oil, results in very fast reactions characterized by a high degree of coal solubilization and deoxygenation. The reaction is catalysed by a mixture of alkali metal carbonates and proceeds readily at 380-400/sup 0/C. The first-stage reaction product appears to be susceptible to further catalytic hydrogenation at 420-460/sup 0/C with gaseous hydrogen yielding 65-70% (on daf feed) of hydrogen-rich distillable oil, composed mainly of naphtha and middle oil. The process flowsheet is presented and the comparative economics of two-stage carbon monoxide/steam-hydrogen and hydrogen-hydrogen coprocessing schemes are discussed.
