PROBLEM TO BE SOLVED: To provide a method for hydrocracking and/or hydrogeneration treatment of hydrocarbon supply raw material using a catalyst.SOLUTION: The catalyst contains: at least one kind of hydrogeneration dehydrogenation element selected from the group containing an independently or mixedly used VIB group element and VIII group nonmetallic element of the periodic table; and carriers each containing at least one kind of porus mineral matrix and at least one kind of dealuminated USY zeolite. In the dealuminated USY zeolite, an overall atom ratio of silicon to aluminum is 2.5-10, a ratio of aluminum atoms outside a network by weight exceeds 10% to the whole mass of aluminum present in the zeolite, a meso pore volume measured by nitrogen porosimetry exceeds 0.07 mLg, and a crystal parameter aof the mesh of an element exceeds 24.28 Å. Nickel of 0.5-3 wt.% to the whole mass of the zeolite is deposited on the USY zeolite. The catalyst has a form of a sulfide.

Abstract:
The present invention is directed to certain catalyst compositions and processes that are capable of reducing sulfur compounds normally found as part of the gasoline fraction streams of fluid catalytic cracking processes. The present invention is a cracking catalyst composition comprising a zeolite in combination with a Lewis Acid containing component, wherein the cracking catalyst composition comprises 0.2% Na2O or less. It has been found that sulfur compounds in hydrocarbon feeds to fluid catalytic cracking processes can be reduced by at least 15% compared to the same composition, which does not comprise the aforementioned Lewis Acid containing component.
