Abstract: A combustion system includes a topping cycle that generates a flow of exhaust gas, a bottoming cycle, and a fuel cell. The fuel cell includes an anode side, a cathode side, and an electrolyte. The cathode side receives the flow of exhaust gas from the topping cycle via a cathode inlet line. The cathode side removes a first portion of pollutants from the exhaust gas. A heat recovery steam generator (HRSG) receives the exhaust gases from the cathode side via a cathode outlet line, and the HRSG generates a flow of steam for use in the bottoming cycle. A bypass line extends from the cathode inlet line to the cathode outlet line. The combustion system further includes a carbon capture system that is fluidly coupled to the HRSG via an HRSG outlet line. The carbon capture system removes a second portion of pollutants from the exhaust gas.

Abstract: Method for the preparation of a sorbent material and for use of such a material for separating gaseous carbon dioxide from a gas mixture, preferably for direct air capture, using a temperature, vacuum, or temperature/vacuum swing process, comprising primary amine moieties immobilized on a solid support, wherein the primary amine moieties, in the α-carbon position, are substituted by one hydrogen and one non-hydrogen substituent, wherein the sorbent material is in the form of a monolith, a layer, fibres, or particles, wherein the non-hydrogen substituent is selected from the group consisting of alkyl, alkenyl, arylalkyl, and wherein the solid support of the sorbent material is a porous material. Starting from a precursor of said sorbent material comprising one or multiple keto-groups, said one or multiple keto groups are converted into said primary amine moieties through a reductive amination.

Abstract: Proposed is a method for manufacturing a catalyst for capture and conversion of carbon dioxide capable of removing carbon dioxide and converting carbon dioxide into other useful materials at the same time by capturing and converting carbon dioxide in flue gas generated during fossil fuel combustion into a carbon resource and a catalyst for capture and conversion of carbon dioxide manufactured by the method of the same. The catalyst for capture and conversion of carbon dioxide according to the present disclosure can reduce carbon dioxide by capturing carbon dioxide in flue gas generated during fossil fuel combustion. It is possible to convert the captured carbon dioxide into other useful materials by converting the collected carbon dioxide into sodium carbonate or sodium hydrogen carbonate as carbon resources.

Abstract: In a general aspect, a carbon dioxide removal system is presented. In some cases, a gas-liquid contactor is wetted with an alkaline capture solution. A first flow from a first gaseous feed including CO2 from a first source is directed to interact with the alkaline capture solution in the gas-liquid contactor, which forms a first CO2-rich alkaline capture solution. A second flow from a second gaseous feed including CO2 from a second, distinct source is directed to interact with the first CO2-rich alkaline capture solution, which forms a second CO2-rich alkaline capture solution. In some cases, the second flow is independent of the first gaseous feed, and a concentration of CO2 in the second CO2-rich alkaline capture solution is higher than a concentration of CO2 in the first CO2-rich alkaline capture solution. CO2 can be separated from the second CO2-rich alkaline capture solution.
