It was found that, under certain conditions, conventional NiO methanation catalyst would completely remove small traces of oxygen from hydrogen-rich gas streams through the reaction of hydrogen and oxygen combining to produce water. The advantage of using this catalyst rather than the traditional Palladium-based "de-oxo" catalyst is that the methanation catalyst is significantly less expensive and is much less sensitive to poisoning from trace impurities in the gas stream.
