Moody, B E; Schuster, J E

Hydrocarbon feedstock is first vaporized in the presence of hydrogen and then the vaporized hydrocarbon feedstock together with excess hydrogen, is gasified to form an effluent gas consisting essentially of methane and aromatic hydrocarbons together with hydrogen and minor amounts of hydrogen sulfide. The process is suitable for the production of a pipeline gas having a heating value of approximately 1,000 Btu/SCF by further processing the effluent, after separation of the aromatic fraction and hydrogen sulfide from the gasifier effluent; the effluent is subject to cryogenic separation of the hydrogen with the hydrogen being recycled to the gasification step and the methane being discharged into a product pipeline. The overall process contemplates revaporization of the aromatic fraction separated from the effluent and regasification to extinction of this fraction. Preferred feedstocks are crude oil, bitumen produced from tar sands, shale oil, liquid volatiles resulting from coking of coal, liquefied coal resulting from solvating coal with a solvent and hydrogen, aromatic hydrocarbons, naphtha, gas oils, crude oil distillates, and crude oil residues. It is contemplated that the gasifier effluent could be used as a feedstream for the production of a hydrogen-carbon monoxide synthesis gas, hydrogen, carbon monoxide or as a source of fuel to be burned in place of oil or other liquid hydrocarbons. 18 claims, 4 figures.
