摘要： A steam methane reformer-integrated fuel cell system includes at least one fuel cell including an anode, a cathode, and an electrolyte matrix. The system includes a steam methane reformer, a water-gas shift reactor, an absorber column, and a pressure swing adsorption (PSA) system. The PSA system is configured to purify the second product stream to output (1) a third product stream of the PSA system having a fourth concentration of hydrogen that is greater than the third concentration of hydrogen and (2) a PSA tail gas. The at least one fuel cell is configured to receive the PSA tail gas from the PSA system as an anode feed gas.

摘要： A molten carbonate fuel cell-powered system for capturing carbon dioxide produced by a steam methane reformer system. Tail gas from a pressure swing adsorption system is mixed with exhaust gas from the fuel cell anode, then pressurized and cooled to extract liquefied carbon dioxide. The residual low-CO2 gas is directed to an anode gas oxidizer, to the anode, to the reformer to be burned for fuel, and/or to the pressure swing adsorption system. Low-CO2 flue gas from the reformer can be vented to the atmosphere or directed to the anode gas oxidizer. Reduction in the amount of CO2 reaching the fuel cell allows the fuel cell to be sized according to the power demands of the system and eliminates the need to export additional power output.
