Catalyst for the simultaneous hydrodemetallization and hydroconversion of heavy hydrocarbon feedstocks and process for preparing the catalyst

摘要

An improved catalyst for use in the hydrodemetallization and hydroconversion of heavy hydrocarbon feedstocks and method of making same and, more particularly, an improved catalyst having two distinct phases supported on a refractory support wherein the first phase effectively stores metals removed from the feestock and the second phase exhibits superior catalytic activity for hydrogenation when processing heavy hydrocarbon feedstocks.
