NOVELTY - Generating gaseous products from a carbonaceous feedstock comprises supplying a first carbonaceous feedstock (12), a first oxygen-rich gas stream (15), and optionally an aqueous stream (18) to a syngas generator (100); reacting the first carbonaceous feedstock in the presence of oxygen; cooling; introducing a second carbonaceous feedstock (32), a hydromethanation catalyst (31), a second oxygen-rich gas stream (22), and the cooled first gas stream to a hydromethanation reactor (200); reacting; and treating methane-enriched product stream.    USE - Method for the generating gaseous products, e.g. methane from a carbonaceous feedstock (claimed).    ADVANTAGE - The method minimizes or eliminates gas recycle loops, decreases complexity, and is inexpensive.    DETAILED DESCRIPTION - Generating gaseous products from a carbonaceous feedstock comprises:    (A) supplying a first carbonaceous feedstock (12), a first oxygen-rich gas stream (15), and optionally an aqueous stream (18) comprising water and/or steam, to a syngas generator (100);    (B) reacting the first carbonaceous feedstock in the presence of oxygen, and optionally the aqueous stream, in the syngas generator, at a first temperature and a first pressure, to produce a first gas stream (20) comprising hydrogen, carbon monoxide, and optionally steam;    (C) cooling the first gas stream, optionally with a quench stream (25) comprising water and/or steam, to generate a cooled first gas stream comprising hydrogen, carbon monoxide, and steam at a second temperature and a second pressure;    (D) introducing a second carbonaceous feedstock (32), a hydromethanation catalyst (31), a second oxygen-rich gas stream (22), and the cooled first gas stream to a hydromethanation reactor (200), the second carbonaceous feedstock comprising a carbon content;    (E) reacting a portion of the carbon content from the second carbonaceous feedstock in the hydromethanation reactor in the presence of oxygen to produce carbon monoxide, hydrogen, and heat energy;    (F) reacting the second carbonaceous feedstock in the hydromethanation reactor in the presence of carbon monoxide, hydrogen, steam and hydromethanation catalyst, at a third temperature and a third pressure, to produce a methane-enriched raw product stream (50) comprising methane, carbon monoxide, hydrogen, and carbon dioxide;    (G) withdrawing the methane-enriched product stream from the hydromethanation reactor; and    (H) treating the methane-enriched product stream.
