Hydrocracking process for converting heavy hydrocarbon into low sulfur gasoline
A hydrocracking process is described wherein heavy hydrocarbon oils having from about 10 to 50% boiling above 1,000/sup 0/F and containing appreciable amounts of sulfur, nitrogen, and metal-containing compounds as well as asphaltenes are converted into a minor fraction of low sulfur residual fuel oil and a major fraction of low sulfur gasoline. The process comprises hydrocracking the heavy oil with molecular hydrogen, at a temperature of about 700/sup 0/-850/sup 0/F in the presence of a sulfur and nitrogen resistant hydrocracking catalyst comprising a hydrogenating component supported upon an amorphous inorganic oxide cracking base to convert the heavy hydrocarbon oil into a gas-oil fraction and a low sulfur residual fraction; separation the gas-oil fraction from the residual fraction; hydrocracking the gas-oil fraction with molecular hydrogen, at a temperature of 700/sup 0/-780/sup 0/F, in the presence of a sulfur and nitrogen resistant hydrocracking catalyst comprising a hydrogenation component supported upon a cation exchanged crystalline silica-alumina zeolitic molecular sieve cracking base to yield low sulfur, low nitrogen gasoline.
