ABSTRACT:
A process for selectively converting H.sub.2 S to S, utilizing a porous catalyst having the atomic proportions covered by the formula Fe.sub.A Zn.sub.B, wherein A has a value of 0.5 to 10 and B has a value of 1 to 2. The catalyst contains substantially no chromium. A gas stream comprising hydrogen sulfide and oxygen is passed over the catalyst at a temperature above the dew point of sulfur and up to about 300.degree. C.
