Abstract
Oxygen is removed from a gas feed such as a landfill gas, a digester gas or an industrial COoff-gas by removing sulfur-containing compounds and siloxanes from the feed gas, heating the feed gas, injecting one or more reactants for oxygen conversion into the heated feed gas, carrying out a selective catalytic oxygen conversion in at least onesuitable reactor and cleaning the resulting oxygen-depleted gas. The reactants to be injected comprise one or more of H, CO, ammonia, urea, methanol, ethanol and dimethylether (DME).
