    Abstract: Disclosed is a method for the production of hydrogen from a H2S-containing gas stream also containing ammonia, comprising subjecting both gas stream to catalytic oxidative cracking of both the H2S and the NH3, so as to form H2, S2 and N2. In this method, preferably, an additional amount of oxygen is added as compared to the amount used for H2S catalytic oxidative cracking. Also, preferably, the contact time of the gas stream with the catalyst is increased. The catalyst preferably is provided as a single bed, and then preferably comprises iron and molybdenum supported by a carrier comprising aluminum. The preferred carrier is alumina. The iron and molybdenum preferably are in the form of sulfides.
