PURIFICATION OF GAS MIXTURES

摘要

Gas purification and selective removal of specific gasses from gas mixtures is of importance for many processes. The method and apparatus of this invention can remove selectively specific gasses like carbon monoxide from gas mixtures that contain hydrogen. The hydrogen and CO containing gas mixture is brought in contact with one side of a membrane, while on the other side of the membrane an oxygen containing gas is provided. The CO will bind to the membrane or to certain chemical species in this membrane on one side, move to the other side of the membrane, where the CO is converted with oxygen to CO2.
