Abstract:
A process for reducing the polynuclear aromatics (PNA) content of a sulfur-containing hydrocarbon stream. The process includes contacting the sulfur-containing hydrocarbon stream with a dearomatization composition comprising a promoter metal component and zinc oxide. The dearomatization composition has enhanced resistance to sulfur poisoning and is also effective to remove sulfur from the hydrocarbon stream.
