Regeneration of hydrogen sulfide sorbents
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.
