A novel high sulfur capacity adsorbent capable of high rates of sulfur adsorption from process streams, which is readily regenerable by simple gas stripping. The adsorbent is characterized as a spinel compound of the formula M[NxAl2-x]O4, where M is one or more divalent cations selected from the gro
A novel high sulfur capacity adsorbent capable of high rates of sulfur adsorption from process streams, which is readily regenerable by simple gas stripping. The adsorbent is characterized as a spinel compound of the formula M[NxAl2-x]O4, where M is one or more divalent cations selected from the group consisting of copper, Group II-B, i.e., zinc, cadmium, and mercury, and chromium, and Iron Group metals, i.e., iron, cobalt, and nickel, and magnesium, N is one or more trivalent cations selected from the group consisting of Group VI-B, i.e., chromium, molybdenum, and tungsten, manganese, and Iron Group metals, i.e., iron, cobalt and nickel, x is a positive number of value greater than 0 and less than 2.0, and the total cationic charge of M[NxAl2-x]is 8. The sorbent readily adsorbes sulfur, e.g., organosulfur compounds and hydrogen sulfide, from gas streams.

In a process for the removal of sulfur compounds from a process stream in which a metal alumina spinel sorbent is used, which sorbent is characterized by the formula: MAl2O4 wherein M is a divalent cation selected from the group consisting of chromium, iron, cobalt, nickel, copper, cadmium, mercury,
In a process for the removal of sulfur compounds from a process stream in which a metal alumina spinel sorbent is used, which sorbent is characterized by the formula: MAl2O4 wherein M is a divalent cation selected from the group consisting of chromium, iron, cobalt, nickel, copper, cadmium, mercury, magnesium, and zinc, the improvement which comprises: significantly increasing the absorbent capacity of the alumina spinel for said sulfur compounds by: (a) providing that M is one or more of the above mentioned divalent cations; and (b) substituting at least 5 mole %, but not as much as 100 mole %, of the aluminum with one or more trivalent cations selected from the group consisting of chronium, molybdenum, tungsten, manganese, iron, cobalt, and nickel.
