NOVELTY - Generating a methane-enriched raw product gas stream (50) from a non-gaseous carbonaceous material (10), comprises (a) supplying to a hydromethanation reactor e.g. (a1) a carbonaceous feedstock (32) derived from the non-gaseous carbonaceous material, (b) reacting a portion of the carbonaceous feedstock in the hydromethanation reactor in the presence of e.g. hydromethanation catalyst at a target operating temperature, and (c) reacting a portion of the carbonaceous feedstock with oxygen to produce carbon monoxide, hydrogen and heat energy.    USE - The process is useful for generating a methane-enriched raw product gas stream from a non-gaseous carbonaceous material.    ADVANTAGE - The process is capable of generating a methane-enriched raw product gas stream from a non-gaseous carbonaceous material in an improved temperature controlled manner.    DETAILED DESCRIPTION - Generating a methane-enriched raw product gas stream (50) from a non-gaseous carbonaceous material (10), comprises (a) supplying to a hydromethanation reactor (a1) a carbonaceous feedstock (32) derived from the non-gaseous carbonaceous material, (a2) a hydromethanation catalyst, (a3) a superheated steam stream and (a4) an oxygen-rich gas stream, where the hydromethanation reactor comprises a fluidized bed having a upper portion above a lower portion, and the superheated steam stream and the oxygen-rich gas stream are introduced into the lower portion of the fluidized bed, (b) reacting a portion of the carbonaceous feedstock in the hydromethanation reactor in the presence of hydromethanation catalyst, carbon monoxide, hydrogen and steam at a target operating temperature to produce a methane-enriched raw gas and a solid by-product char, where the methane-enriched raw gas comprises methane, carbon monoxide, hydrogen, carbon dioxide, hydrogen sulfide, steam, heat energy and entrained fines, and (c) reacting a portion of the carbonaceous feedstock with oxygen to produce carbon monoxide, hydrogen and heat energy, where (i) the reaction of step (b) predominates in the upper portion of the fluidized bed, (ii) the reaction of step (c) predominates in the lower portion of the fluidized bed, and (iii) the carbonaceous feedstock as supplied to the hydromethanation reactor comprises an elevated moisture content of greater than 10-25 wt.% (based on the total weight of the carbonaceous feedstock), to the extent that the carbonaceous feedstock is substantially free-flowing.
