A composition useful for the adsorptive removal of hydrogen sulfide from a gas or liquid stream, the composition comprising ferric oxide and a zeolyte group. The zeolyte group may comprise aluminum and silicon at a ratio in the range from about 1 part aluminum to 100 parts silicon to about 100 parts aluminum to 1 part silicon, and have a mix of amorphous aluminosilicate and structured zeolyte, wherein the structured zeolyte comprises a distribution of zeolytic cells ranging in size from about 3 Angstroms to about 16 Angstroms. Also disclosed is a process for removing hydrogen sulfide from various process stream by contact with such a composition. |
