Title:
二酸化炭素化学吸収液及び二酸化炭素分離回収方法
Document Type and Number:
Japanese Patent JP6530167
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an acid gas chemical absorption liquid where water is not needed as a solvent, the temperature dependence of an acid gas absorption amount is large, a large amount of an acid gas is absorbed at about room temperature and almost all absorbed acid gas can be released at 100°C or lower and to provide an energy saving and highly efficient acid gas separation recovery method using the same.SOLUTION: An acid gas chemical absorption liquid includes an ionic liquid consisting of a cation and an anion. The cation is aminium having one or more primary amino groups or secondary amino groups and ethylene diamine or a propylene diamine skeleton. In an acid gas separation recovery method, an acid gas is absorbed by the acid gas chemical absorption liquid by being brought into contact with a mixed gas containing the acid gas and the acid gas is selectively separated from the mixed gas.
