TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further comprises: compressing the anode exhaust and/or the portion of the anode exhaust prior to reacting the portion of the anode exhaust under effective Fischer-Tropsch conditions; exposing a portion of the anode exhaust stream to a water gas shift catalyst to form a shifted anode exhaust; removing water and CO2 from a portion of the shifted anode exhaust; performing an effective amount of an endothermic reaction to maintain a temperature differential between an anode inlet and an anode outlet of less than or equal to 100 degrees C; and recycling a portion of the gaseous product to the anode inlet and/or to the cathode inlet. The recycling step comprises: removing CO2 from the gaseous product to produce a CO2-containing stream and a separated syngas effluent comprising CO2, CO and H2 such that the CO2-containing stream has a CO2 content, which is greater than a CO2 content in the gaseous product; oxidizing the portion of the separated syngas effluent; and recycling a portion of the separated syngas effluent to the cathode inlet. A portion of the separated syngas effluent is oxidized prior to the recycling of the separated syngas effluent to the cathode inlet. Preferred Components: A ratio of H2 and CO in the anode exhaust is least about 2.5:1. The shifting Fischer-Tropsch catalyst comprises iron. The cathode inlet stream comprises exhaust from a combustion turbine. A ratio of H2 and CO in the anode exhaust is less than or equal to 2.3:1. An amount of the reformable fuel introduced into the anode and/or the internal reforming element associated with the anode is 75% greater than an amount of hydrogen reacted in the molten carbonate fuel cell to generate electricity. A ratio of net moles of syngas in the anode exhaust to moles of CO2 in a cathode exhaust is 2:1. A fuel utilization in the anode is less than or equal to 50%, and a CO2 utilization in the cathode is 60%. The molten carbonate fuel cell is operated to generate electrical power at a current density of 150 mA/cm2 to 40 mW/cm2 of waste heat. The endothermic reaction consumes 40% of the waste heat. An electrical efficiency for the molten carbonate fuel cell is 10-40%, and a total efficiency for the fuel cell is 55%. The molten carbonate fuel cell is operated at a thermal ratio of 0.25-1. An amount of the reformable fuel introduced into the anode and/or the internal reforming element associated with the anode provides a reformable fuel surplus ratio of 1.5. The gaseous product comprises a tail gas stream comprising (i) unreacted H2, (ii) unreacted CO and (iii) 4C hydrocarbonaceous and/or 4C oxygenate compounds.
