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