Use of hydrogen to regenerate metal oxide hydrogen sulfide sorbents

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 m...

More Information
Summary: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.
