Abstract
Abstract A hydrocarbon conversion catalyst suitable for the conversion of heavy hydrocarbon oils containing large amounts of metallic contaminants, such as petroleum residua, comprises an inorganic 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.
