HYDROCRACKING AND HYDROTREATING CATALYTIC COMPOSITIONS COMPRISING A ZEOLITE AND REGENERATED, SPENT CATALYST AND USES THEREOF

摘要

The invention relates to a composition useful as a hydrotreating or hydrocracking catalyst, where fresh catalyst useful in hydrotreating or hydrocracking is combined with spent catalyst, and optionally with additional active metal. The resulting compositions can be used in hydrotreating or hydrocracking but not FCC processes.
