Abstract
While contacting under regeneration conditions an oxygen-containing stream with a sorbent comprising a promoter metal and zinc sulfide which has been sulfurized by contact with sulfur-containing hydrocarbons such as cracked-gasolines and diesel fuel, the oxygen partial pressure is controlled in a range of 0.5 to 2.0 psig to minimize sulfation of the sorbent.
