ABSTRACT OF THE DISCLOSURE A process wherein a particulate sorbent mass of zeolite which has been ion-exchanged with zinc or cad- mium to provide pore size openings of about 5.ANG., and greater, particularly zinc, is contacted with a moist hydrocarbon process stream which contains sulfur, sulfur compounds, and other contaminants, these being adsorbed onto said particulate sorbent mass, and the process stream thereby denuded of said sulfur, sulfur compounds, and other contaminants. Thereafter, the sulfur, sulfur com- pounds, and other contaminants, are readily desorbed, or removed from said particulate sorbent mass by contacting, and purging same with a gas stream, suitably hydrogen, or a hydrogen-containing gas, at elevated temperature.
