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.
