Adjusting the CO ratio in syngas can be achieved through several methods:
Water-Gas Shift Reaction: This reaction adjusts the CO/H2 ratio by converting CO and water (H2O) into CO2 and H2. It is typically conducted in multiple stages using different catalysts. Steam Methane Reforming: This process involves the reaction of methane (CH4) with steam to produce syngas with a controlled CO/H2 ratio. Partial Oxidation: This method involves the partial combustion of hydrocarbons to create syngas, where the CO ratio can be adjusted by controlling the oxygen supply.
