Abstract
A moderate pressure hydrocracking process in which a highly aromatic, substantially dealkylated feedstock is processed directly to high octane gasoline by hydrocracking over a monofunctional acidic cracking catalyst, preferably comprising a large pore size, crystalline alumino-silicate zeolite hydrocracking catalyst such as zeolite Y. The feedstock which is preferably a light cycle oil obtained from catalytic cracking with an aromatic content of at least 50, usually at least 60 percent and an API gravity not more than 25. The hydrocracking typically operates at 600-1000 psig at moderate to high conversion levels to mazimize the production of monocyclic aromatics which provide the requiste octane value to the product gasoline.
