Patent ID: 7125484

Claim:
A downflow process for the desulfurization of a fluid cracked naphtha comprising the steps of: (a) subjecting a cracked naphtha to thioetherification prior to: (b) feeding said fluid cracked naphtha containing organic sulfur, hydrogen, and gas oil compounds to a downflow single pass reactor containing a bed of hydrodesulfurization catalyst; (c) contacting said organic sulfur compounds and said hydrogen in the presence of said hydrodesulfurization catalyst at temperature above 500° F. and pressures below 300 psig to provide a boiling mixture in the bed thereby reacting a portion of said organic sulfur compounds with hydrogen to form hydrogen sulfide; (d) removing a naphtha product, H 2 S and hydrogen from said reactor, said naphtha product having a lower sulfur content than the fluid cracked naphtha feed.
