Abstract
Acid gases are removed from a coal gasification gas, followed by contacting the gas with a reduced iron catalyst at conditions selected to primarily produce methane, and some olefins together with carbon dioxide as byproduct. After separation of carbon dioxide byproduct, the gas is contacted with a nickel catalyst under methanation conditions to produce additional methane and convert olefins to alkanes to thereby produce a pipeline gas having an increased heating value.
