ABSTRACT:
A process for producing a high octane gasoline from a hydrocarbon feedstock in which the feedstock is contacted in the presence of hydrogen under hydrocracking conditions, preferably ammonia-rich hydrocracking conditions, with a hydrocracking catalyst comprising at least one hydrogenation metal component in combination with a cracking component. The preferred cracking components are Y zeolites and the catalyst preferably contains a nickel hydrogenation metal component, particularly in an amount greater than 13 weight percent, calculated as NiO. The catalyst may also contain a Group VIB metal component, such as a molybdenum component, particularly in a mole ratio greater than about 2 to 1, calculated as NiO to Group VIB metal trioxide. It has been found that such a process produces gasoline fractions having substantially increased research and motor octane numbers.
