Description
Summary:The global decarbonization policy has led to the widespread development of solid oxide fuel cells (SOFCs). Fuel cells are electrochemical devices that convert the fuel oxidation chemical energy directly into electrical and thermal energy. However, during the fuel cell operation, carbon dioxide is released, which must be captured and utilized. CO2 capture can be carried out by adsorption, absorption and membrane methods. A laboratory setup was created to determine the efficiency of carbon dioxide capture and tested some absorbents. According to the results of the experiments, the NaOH solution showed the highest sorption capacity. Based on the data obtained, a technological scheme and an installation for carbon dioxide capture and utilization have been developed. An alkaline solution of sodium hydroxide 6% was used as an absorbent. The absorbent is subsequently regenerated and reused. Solid waste in the form of a suspension (calcium carbonate solution) is dehydrated in a filter press and can then be used as a raw material for the construction industry.
