Patent ID: 6881324

Claim:
A process for the desulfurization of a fluid cracked naphtha comprising the steps of: (a) feeding hydrogen and a fluid cracked naphtha containing organic sulfur compounds to a distillation column reactor containing a bed of hydrodesulfurization catalyst; (b) concurrently in said distillation column reactor (i) 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 thereby reacting a portion of said organic sulfur compounds with hydrogen to form hydrogen sulfide; (ii) fractionating said fluid cracked naphtha into two fractions by fractional distillation, (c) removing a naphtha product as overheads from said distillation column reactor, said naphtha product having a lower sulfur content than the fluid cracked naphtha feed; and (d) feeding gas oil to said distillation column reactor whereby a liquid phase within said distillation column at the reaction conditions is assured.
