Abstract
A process is disclosed for removing sulfur from a naphtha feedstream comprising contacting a naphtha feed with a platinum on alumina sulfur conversion catalyst under mild reforming conditions so that thiophenic and other organic sulfur compounds are converted to hydrogen sulfide without any significant cracking of the naphtha feed. Thereafter, the naphtha feed stream is contacted with a sulfur sorbent that has a metal component selected from Group I-A or Group II-A of the Periodic Table supported on a refractory inorganic oxide support, to remove hydrogen sulfide from the naphtha feed.
Claims6
A process for removing sulfur and sulfur compounds from a naphtha feed comprising:
- (a) contacting a maphtha feed with a platinum on alumina catalyst in the presence of added hydrogen so as to convert thiophenic or organic sulfur compounds to hydrogen sulfide under mild reforming conditions wherein the temperature is no greater than about 500.degree. C. and the pressure is no greater than about 250 psig;
- and
- (b) contacting the naphtha from step (a) with a sulfur sorbent which comprises a Group I-A or Group II-A metal supported on a porous refractory inorganic oxide support to remove hydrogen sulfide from the naphtha feed.
