METHODS FOR CO-PROCESSING CARBON DIOXIDES AND HYDROGEN SULFIDE

摘要

A method for co-processing H2S and CO2 in an electrolyzer includes feeding a first gas stream having H2S to an anode and feeding a second gas stream having CO2 to a cathode. The H2S is split into hydrogen ions and elemental sulfur. The hydrogen ions are transferred from the anode to the cathode, and the CO2 is hydrogenated with the transferred hydrogen ions. A method for producing electricity in a fuel cell includes feeding a first gas stream having H2S and CO to an anode, and feeding a second gas stream having oxygen to a cathode. The H2S and CO forms hydrogen ions and carbonyl sulfide. The hydrogen ions are transferred from the anode to the cathode. The transferred hydrogen is oxidized with the oxygen of the second gas stream, and electricity formed from the oxidation is collected.
