Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

C10G 4500

US Classification:

208213, 208217, 585826, 502 34, 502 38, 502 53

Abstract:

A process to regenerate metal oxide desulfurization sorbents using an oxidizing and reducing atmosphere. The sorbents may be mono- or multi-metallic in nature, and preferably comprise Cu, Ni and/or Co. If desired, secondary metals may be incorporated to increase regeneration efficiency and/or capacity. Other additives may be used to suppress hydrocarbon cracking. A sorbent containing Zn may be combined with an Fe, Co, Ni, Mo, or W catalyst or a noble metal catalyst and combinations thereof.

Abstract:

A process to regenerate iron-based hydrogen sulfide sorbents using steam. The steam is preferably mixed with hydrogen-containing gas and/or an inert gas, such as nitrogen. In a preferred embodiment, the sorbent is first exposed to the steam and then exposed to a hydrogen-containing gas at regeneration conditions.

Abstract:

A process to regenerate a spent hydrogen sulfide sorbent comprised of a sorbent metal selected from Fe, Ni, Co, and Cu on a refractory oxide support using hydrogen gas. The sorbent metal component may be mono- or multi-metallic in nature, and preferably comprise Ni and/or Co. If desired, secondary metals may be incorporated to increase regeneration efficiency and/or capacity. Other additives suppress hydrocarbon cracking.
