Abstract

Disclosed is a catalyst suitable for the catalytic oxidative cracking of a H2S-containing gas stream, particularly in the event that the stream also contains methane and/or ammonia. The catalyst comprises iron and molybdenum supported by a carrier comprising aluminum. The carrier preferably is alumina. The iron and molybdenum preferably are in the form of sulphides. Also disclosed is a method for the production of hydrogen from a H2S-containing gas stream, comprising subjecting the gas stream to catalytic oxidative cracking so as to form H2 and S2, using a catalyst in accordance with any one of the preceding claims.
