ABSTRACT:
This invention is a process for the continuous and simultaneous retorting and hydrocracking of the carbonaceous materials found in such carbon containing solids as oil shale, coal, tar sands, lignite, and/or other carbon containing solids, and/or heavy liquids to produce low boiling liquid hydro-carbons and/or a gaseous product suitable for the subsequent production of methane or synthetic natural gas. It is a process by which high to very high molecular weight carbonaceous materials can be effectively and economically converted at high yields to either a low boiling crude of from 30.degree. to 60.degree. API gravity or a gas suitable for the subsequent production of methane, or both. The process consists of creating a catalytically reactive mass, whose active component is activated spent shale, in a reaction zone to which is fed oil shale or a mixture of oil shale and other carbonaceous feeds to be liquified-gasified, and the liquifying-gasifying agents, steam and oxygen; and from which is obtained a low boiling liquid hydrocarbon and gas, and spent shale and ash which are essentially free of any carbonaceous residue. The temperature at which the reaction zone is operated determines to a great extent the relative distribution of the products between liquids and gases. The higher the temperature the greater will be the percentage of the feed which is gasified.
