Hydrocarbon conversion process utilizing a catalyst comprising a zeolite, a zirconia-containing matrix and an adsorbent

摘要

A hydrocarbon conversion process suitable for the conversion of heavy hydrocarbon oils containing large amounts of metallic contaminants, such as petroleum residua, utilizes a catalyst comprising an inroganic oxide gel matrix comprising a major amount of silica, and minor amounts of zirconia and alumina, from about 15 to about 40 weight percent of an adsorbent such as bulk alumina, and a crystalline aluminosilicate zeolite.
