METHOD FOR ADSORPTIVE SEPARATION OF CARBON DIOXIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for adsorptive separation of carbon dioxide in a gas such as exhaust combustion gas exhausted from an electric power station. SOLUTION: A low silica X type zeolite molded body containing at least 95% low silica X type zeolite with a molar ratio of SiO2/Al2O3 of 1.9-2.1 is brought into contact with a mixed gas containing carbon dioxide with a molar fraction of at least 5% and a gas with a lower polarity than carbon dioxide to perform adsorptive separation of carbon dioxide.
