NOVELTY - Generation of electrical power from nongaseous carbonaceous material involves introducing into a hydromethanation reactor (200) a carbonaceous feedstock (32) derived from non-gaseous carbonaceous material (10), hydromethanation catalyst (31), and superheated hydromethanation gas feed stream (12); reacting with carbon monoxide, hydrogen, steam and hydromethanation catalyst to produce methane-enriched raw product; removing portion of hydrogen sulfide; introducing oxygen-containing gas stream and fuel mixture into a fuel cell; and electrochemically reacting.    USE - Method for generating electrical power from nongaseous carbonaceous material.    ADVANTAGE - The method has higher efficiency and reduces the use of oxygen.    DETAILED DESCRIPTION - Generation of electrical power from nongaseous carbonaceous material comprises:    (A) introducing into a hydromethanation reactor (200) a carbonaceous feedstock (32) derived from non-gaseous carbonaceous material (10), a hydromethanation catalyst (31), and a superheated hydromethanation gas feed stream (12) comprising steam, hydrogen and carbon monoxide;    (B) reacting the carbonaceous feedstock in hydromethanation reactor in the presence of carbon monoxide, hydrogen, steam and hydromethanation catalyst to produce a methane-enriched raw product;    (C) withdrawing a methane-enriched product stream from the hydromethanation reactor, where the methane-enriched raw product stream comprises methane, carbon monoxide, hydrogen, carbon dioxide, hydrogen sulfide, steam and heat energy;    (D) recovering a portion of heat energy from methane-enriched raw product stream;    (E) removing a substantial portion of the hydrogen sulfide and, optionally, at least a predominant portion of carbon dioxide, from the methane-enriched raw product stream to produce a sulfur-depleted raw product stream;    (F) introducing into a fuel cell, an oxygen-containing gas stream and a fuel mixture, the fuel cell comprising an anode section and a cathode section separated by an electrolyte section, the oxygen-containing gas stream being introduced into the cathode section and the fuel mixture being introduced into the anode section, the fuel mixture comprising methane and hydrogen from the sulfur-depleted raw product stream;    (G) electrochemically reacting in the fuel cell oxygen from oxygen-containing gas stream with fuel mixture to generate electrical power and heat energy;    (H) withdrawing from the fuel cell, an oxygen-depleted cathode exhaust stream and an anode exhaust stream, where both the oxygen-depleted cathode exhaust stream and the anode exhaust stream comprise heat energy, and where the anode exhaust stream further comprises methane, hydrogen, carbon monoxide, carbon dioxide and steam;    (I) recovering a portion of heat energy from anode exhaust stream to produce a cooled anode exhaust stream;    (J) removing a substantial portion of the carbon dioxide from the cooled anode exhaust stream to generate a carbon dioxide-depleted anode exhaust stream; and    (K) optionally generating carbon monoxide and hydrogen from a portion of methane in the carbon dioxide depleted anode exhaust stream; where the hydrogen and carbon monoxide in the superheated hydromethanation gas feed stream comprises hydrogen and carbon monoxide from carbon dioxide-depleted anode exhaust stream, and hydrogen and carbon monoxide generated from methane in carbon dioxide-depleted anode exhaust stream.    An INDEPENDENT CLAIM is included for an apparatus for generating electrical power from a non-gaseous carbonaceous material.
