ABSTRACT:
This invention relates to a process for treating a feed gas stream containing CO.sub.2 and mercaptans by contacting the feed gas stream with a CO.sub.2 -selective adsorbent under conditions effective to produce a CO.sub.2 -depleted feed gas stream which is thereafter subjected to contact with an alkaline scrubbing solution under mercaptan absorption conditions effective to produce a mercaptan- and a CO.sub.2 -depleted product gas stream and a mercaptide-containing scrubbing solution. At least a portion of the product gas stream may be utilized to regenerate the CO.sub.2 -selective adsorbent and the mercaptide-containing scrubbing solution may be regenerated by contacting same with oxygen in the presence of an oxidation catalyst.
