Child, E T; Robin, A M

A methane-rich gas stream is produced by catalytic methanation of synthesis gas feed comprising H/sub 2/ and CO. When the mole percent CO in the synthesis gas feed to the methanator is greater than 10 mole percent, and the mole ratio H/sub 2//CO is in the range of greater than 1.0 to 3, by adjusting the mole percent CO/sub 2/ in the synthesis gas feed to the methanator to a value in the range of about 0.5 to 20, and the mole ratio H/sub 2//CO/sub 2/ in the range of about 2 to 60 and preferably less than 3.9 it was unexpectedly found that a product gas is produced having a gross heating value which is greater than that which is obtained from a dry CO/sub 2/-free methanator feed gas.
