Title (EN) SYNGAS PRODUCTION BY CO2 REDUCTION PROCESS
(FR) OBTENTION DE GAZ DE SYNTHÈSE PAR UN PROCÉDÉ DE RÉDUCTION DE CO2
Abstract:
(EN) 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 + 1.5 O2 → 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 + 2 H2S → 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.
(FR) L'invention concerne un procédé d'obtention de gaz de synthèse (syngaz) qui comporte la réaction endothermique entre CO2 et H2S, l'apport énergétique étant fourni par l'oxydation exothermique d'une petite partie de H2S en SO2 selon le schéma de réaction suivant : R2 : H2S + 1.5 O2 → SO2 + H2O, ledit procédé étant mis en œuvre selon le schéma global de réaction théorique suivant R1, ne prenant pas en compte la réaction exothermique susmentionnée R2, R1 : CO2 + 2 H2S → CO + H2 + S2 + H2O, la quantité d'oxygène introduite étant comprise entre 5 % et 25 % en volume par rapport au volume total du mélange gazeux de réactifs introduit.
