Abstract:
1. A method for capturing carbon dioxide from a combustion source, the method comprising: introducing a fuel stream and an O performing a combustion reaction in the combustion zone to generate a combustion exhaust, the combustion exhaust comprising CO processing a cathode inlet stream, the cathode inlet stream comprising at least a first portion of the combustion exhaust, with a fuel cell array of one or more molten carbonate fuel cells to form a cathode exhaust stream from at least one cathode outlet of the fuel cell array, the one or more molten carbonate fuel cells comprising one or more fuel cell anodes and one or more fuel cell cathodes, the one or more molten carbonate fuel cells being operatively connected to the combustion zone through at least one cathode inlet; reacting carbonate from the one or more fuel cell cathodes with H separating CO passing at least a combustion-recycle portion of the CO recycling at least an anode-recycle portion of the CO wherein a fuel utilization in the one or more fuel cell anodes is about 65% or less.
