摘要： Methanation of carbon oxides such as carbon monoxide and carbon dioxide with hydrogen to produce methane is carried out with the aid of a heated catalyst which is the calcination product of a serpentine containing nickel and optionally magnesium and other elements together with silicon in the essentially laminar nickel serpentine. The catalysts exhibit good conversion at relatively low temperatures, are relatively insensitive to high temperature excursions, and have an extended life.
