  • Zero emissions sulphur recovery process with concurrent hydrogen production
    Patent number: 10654719
    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.
    Type: Grant
    Filed: December 23, 2015
    Date of Patent: May 19, 2020

  • Syngas production by COreduction process
    Patent number: 9630839
    Abstract: A process for producing synthesis gas (syngas) comprising the endothermic reaction between CO2 and H2S, wherein the energetic supply is provided by the exothermic oxidation of a small portion of H2S to SO2 according to the following reaction scheme: R2: H2S+1.5O2?SO2+H2O said process being carried out according to the following overall theoretical reaction scheme R1, not taking into account the aforementioned exothermic reaction R2, R1: CO2+2H2S?CO+H2+S2+H2O wherein the amount of fed oxygen is comprised between 5% and 25% by volume over the total volume of fed reactants gaseous mixture.
