Abstract
During the regeneration of a sulfurized sorbent comprising zinc aluminate, a promoter metal and zinc sulfide by contact with an oxygen-containing stream to convert at least a portion of said zinc sulfide to zinc oxide the average sulfur dioxide partial pressure in the regeneration zone is controlled within the range of from about 0.1 to about 10 psig to minimize sulfation of the sorbent.
