An integrated process for the conversion of coal to liquid and gaseous fuels is disclosed. Coal and oil are hydrocracked in the presence of a particulate mixture of sand or clay and an iron and chromium alloy to form carbon-coated sand and an overhead product comprising cracked oil vapors and fuel gases. The carbon is removed from the sand to form carbon monoxide with the concomitant generation of heat. The carbon monoxide is used to reduce oxidized iron and chromium alloy located in a hydrogen generating bed. Steam is passed into the bed of reduced metallic alloy to form hydrogen for use in the coal reactor and the regenerated particulate mixture of sand and iron and chromium alloy is returned to the coal reactor to continue the sequence of carbon removal and to provide heat for the hydrocracking reaction.
