Improved process for the production of a methane-rich product gas stream comprising the following steps: partial oxidation of a hydrocarbonaceous fuel feed employing a H2O/fuel weight ratio of 2.2 to 2.9 and an atomic ratio of oxygen in the substantially pure oxygen to carbon in the fuel of 0.80 to 0.84 to produce a process gas stream comprising principally H2, CO and CH4 in which the mole ratio H2/CO is 1 to 2.5, the mole % CH4 is 15 or more, and the particulate carbon is 13 weight % (basis carbon in the fuel) or less; cooling the process gas stream and separating H2O, CO2, carbon, and gaseous impurities; reacting together the H2 and CO in said process gas stream in a catalytic methanation zone to produce a methane-rich gas stream principally comprising CH4 and containing gaseous members selected from the group consisting of H2, CO, H2O, CO2, and mixtures thereof; and removing said H2O and CO2 to produce a methane-rich product gas stream comprising about 93 mole percent of CH 4. By means of the subject invention there is produced a high heating value clean fuel gas or a substitute natural gas of about 960 BTU per SCF or more.
