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.

Process for separating other sulfur compounds from a gaseous mixture containing one or more mercaptans, and other sulfur compounds, characterized in that the gaseous mixture is treated with an impregnated solid material suitable for selective adsorption of the sulfur compounds SO2, H2S, CS2, and COS

Process for separating other sulfur compounds from a gaseous mixture containing one or more mercaptans, and other sulfur compounds, characterized in that the gaseous mixture is treated with an impregnated solid material suitable for selective adsorption of the sulfur compounds SO2, H2S, CS2, and COS; said impregnated solid material comprising a solid material selected from the group consisting of silica, alumina, clay minerals, zeolites, and mixtures thereof, as well as an active agent selected from the group consisting of monoethanolamine, diethanolamine, ethylenediamine, derivatives of these amines, and metal-containing complexes of these amines and derivatives; said solid material being impregnated with said active agent in an amount from 1 to 10 mmol of active agent per gram of solid material.
