ABSTRACT:
A hydrocarbonaceous feedstock upgrading process is disclosed. Spent nickel arsenide-containing catalyst from demetallation guard chambers or hydroprocessing operations are utilized to upgrade the hydrocarbonaceous feedstock prior to dearsenation. The spent catalysts have significant activity for diolefin saturation and CCR removal at temperatures low enough to reduce olefin polymerization reactions.
