Provided is a novel catalyst for use in the second stage of a two-stage hydrocracking process. The present process comprises hydrocracking a hydrocarbon feed in a first stage. The catalyst in the first stage is a conventional hydrocracking catalyst. The product from the first stage can then be transferred to a second hydrocracking stage. The catalyst used in the second stage of the present hydrocracking process comprises a base impregnated with metals from Group 6 and Groups 8 through 10 of the Periodic Table, and an organic acid. The base of the catalyst used in the present second hydrocracking stage comprises alumina, an amorphous silica-alumina (ASA) material, and a USY zeolite. Improved naphtha production is achieved.
A two stage hydrocracking process comprising:
A hydrocracking catalyst comprising a base of alumina, an amorphous silicia-alumina, and a USY zeolite, with the base impregnated with at least one Group 6 metal and at least one Group 8-10 metal, and an organic acid.
