Ernst Jorn: Process for preparing methane rich gases. Haldor Topsoe, Lawrence Rosen, E Janet Berry, December 19, 1978: US04130575 (236 worldwide citation)

Hydrogen and carbon oxides are reacted to form methane by passing an inlet stream of preheated methanation synthesis gas together with a recycle stream of product gas through a catalyst bed in an adiabatic methanation reactor. The inlet temperature is between 250.degree. and 350.degree. C, the outle ...
