A process wherein a particulate mass of a metal alumina spinel, MAl2O4 wherein M is chromium, iron, cobalt, nickel, copper, cadmium or mercury, particularly zinc alumina spinel (ZnAl2O4), is contacted with a process stream which contains sulfur, sulfur compounds, and other contaminants, these being
A process wherein a particulate mass of a metal alumina spinel, MAl2O4 wherein M is chromium, iron, cobalt, nickel, copper, cadmium or mercury, particularly zinc alumina spinel (ZnAl2O4), is contacted with a process stream which contains sulfur, sulfur compounds, and other contaminants, these being adsorbed onto said particulate mass of metal alumina spinel, and the process stream thereby denuded of said sulfur, sulfur compounds, and other contaminants. Thereafter, the sulfur, sulfur compounds, and other contaminants, are readily desorbed, or removed from said particulate mass of metal alumina spinel by contacting, and purging same with a relatively clean gas stream, suitably hydrogen, hydrogen-containing gas, or an inert gas, at elevated temperature.

A process for the removal of sulfur from a sulfur containing process stream which comprises contacting said stream with a metal alumina spinel sorbent characterized by the formula M Al2O4 wherein M is chromium, iron, cobalt, nickel, copper, cadmium, mercury, or zinc to adsorb sulfur thereon. In a pr
A process for the removal of sulfur from a sulfur containing process stream which comprises contacting said stream with a metal alumina spinel sorbent characterized by the formula M Al2O4 wherein M is chromium, iron, cobalt, nickel, copper, cadmium, mercury, or zinc to adsorb sulfur thereon. In a process for the removal of sulfur from a sulfur containing process stream wherein a series of on-stream reactors are provided with beds of a sulfur sensitive platinum-containing catalyst, a naphtha feed with hydrogen is cocurrently passed sequentially through said series of reactors, and a vaporous effluent rich in hydrogen is taken from the last reactor of the series, hydrogen is separated from the products and recycled, the improvement which comprises contacting said hydrogen recycle stream, prior to its recycle, with a metal alumina spinel sorbent characterized by the formula M Al2O4 wherein M is chromium, iron, cobalt, nickel, copper, cadmium, mercury, or zinc to adsorb sulfur thereon.
