Patent
·
OSTI ID:6982650
This patent describes a process for removing sulfur and sulfur compounds from a naphtha feed. It comprises: contacting a naphtha 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[degrees]C and the pressure is no greater than about 250 psig; and contacting the naphtha 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.
