초록

A system employing a regenerable zinc-oxide based sorbent to remove one or more contaminants from an incoming gas stream. The contaminant-depleted gas stream can then be used for any subsequent application, while at least a portion of the contaminant-laden sorbent can be regenerated via a step-wise regeneration process. In one embodiment, sorbent regenerated via the step-wise regeneration process can comprise less sorbent-damaging compounds than traditional sorbents exposed to conventional regeneration processes.

청구항

What is claimed is: 1. A process comprising: (a) contacting an sulfur-containing gas stream with an initial sorbent in a sorption zone to thereby produce an sulfur-depleted product stream and a sulfur-laden sorbent, wherein said initial sorbent comprises Zn and a promoter metal; and (b) contacting at least a portion of said sulfur-laden sorbent with a regeneration gas stream in a regeneration zone under regeneration conditions to thereby produce a regenerated sorbent and an off-gas stream, wherein said contacting of step (b) includes introducing said re...
