Method for producing hydrocarbon fuels and fuel gas from heavy polynuclear hydrocarbons by the use of molten metal halide catalysts

Patent ·
OSTI ID:7035867

A process developed by Continental Oil Co., under contract to the US Department of Energy, improves upon earlier schemes for producing hydrocarbon fuels and fuel gas from heavy polynuclear hydrocarbons by the use of molten metal halide catalysts. By reducing the severity of the attendant reaction conditions, the new method considerably lowers the cost of the equipment needed to carry out the conversion process. Specifically, these improvements include 1) contacting the heavy feedstocks and hydrogen in the presence of the molten metal halide in the hydrocracking zone at reaction conditions effective to convert about 60-90 wt % of the feedstock to lighter hydrocarbon fuels, 2) separating at least a major portion of the lighter hydrocarbon fuels from the spent catalyst with oxygen in a liquid-phase gasification zone at a temperature and pressure sufficient to vaporize about 25-75 wt % of the spent metal halide, the oxygen being introduced in an amount sufficient to remove 60-90 wt % of the carbon contained in the spent catalyst to produce a fuel gas and regenerated metal halide, and 4) incinerating the spent molten metal halide by combusting the carbon and sulfur compounds contained in it.
