ABSTRACT:
A process for separating sulfur-containing compounds other than mercaptans from gaseous streams. A gaseous stream including mercaptans and other sulfur-containing compounds is brought into contact with a solid supporting material coated with a thin layer of an amine-containing active agent capable of selectively adsorbing the sulfur-containing compounds other than mercaptans. This process permits the monitoring of mercaptans in gaseous streams without interference from other sulfur-containing compounds, as well as the purification of mercaptans.
