PROCESS FOR REMOVING HYDROGEN SULPHIDE FROM GASES AND ABSORBENT FOR USE IN SUCH A PROCESS

摘要

Process for removing H2S from gases, which process comprises contacting a H2S-containing gas with a solid absorbent comprising an intimate mixture of zinc oxide and a zeolite having a pore size larger than 0.40 nm at a temperature above 300 DEG C, and regenerating spent absorbent by passing an oxygen-containing gas over the absorbent at a temperature above 400 DEG C.
