PROCESS FOR THE HYDROGENATION OF AROMATICS IN A HYDROCARBON FEEDSTOCK THAT CONTAINS A THIOPHENEIC COMPOUND

摘要

A process for the hydrogenation of aromatics contained in a hydrocarbon feedstock and for the bulk sulfiding of a nickel-based catalyst to enhance the activity and catalyst life thereof. The process includes passing at the start-of-run a dispersed hydrocarbon feedstock through a bed of the nickel-based catalyst at an elevated temperature effective in promoting the bulk sulfiding the nickel-based catalyst so as to thereby increase its activity or catalytic life, or both.
