Abstract: Disclosed is a catalyst suitable for the catalytic oxidative cracking of a H2S- containing gas stream. The catalyst comprises at least one or more active metals selected from the group consisting of iron, cobalt, and nickel, supported by a carrier comprising ceria and alumina. The active metal is preferably in the form of its sulphide. 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 composition claims.

Abstract: Disclosed is a process for the concurrent production of hydrogen and sulphur from a H2S-containing gas stream, with zero emissions. The method comprises the thermal oxidative cracking of H2S so as to form H2 and S2. Preferably, the oxidation is conducted using oxygen-enriched air, preferably pure oxygen. The ratio H2S/O2 in the feedstock is higher than 2:1, preferably in the range of 3:1-5:1.

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.

Abstract: Disclosed is a process for the concurrent production of hydrogen and sulphur from a H2S-containing gas stream, with reduced, and preferably zero, emissions. The method comprises the catalytic oxidative cracking of H2S so as to form H2 and S2. Preferably, the oxidation is conducted using oxygen-enriched air, preferably pure oxygen. The process is conducted in a reaction chamber comprising a bifunctional catalyst material, so as to favor both the partial oxidation of H2S and the dissociation thereof.
