DESULFURIZATION WITH SORBENT REGENERATION

摘要

A process is provided for removing sulfur compounds, such as hydrogen sulfide, thiophenes, etc., out of a hydrocarbon fluid, such as gasoline or diesel fuel, by contacting the hydrocarbon fluid with a sorbent, such as zinc oxide, containing a promotor metal, such as nickel, to produce a desulfurized hydrocarbon fluid and sulfided sorbent. The sulfided sorbent is regenerated under conditions to maintain the average oxygen partial pressure less than about 2 p.s.i. so as to convert the metal sulfide into metal oxide while minimizing sulfation of the sorbent.
