Description

technical field

[0001] The invention belongs to the technical field of gas separation, in particular to an absorbent for recovering carbon dioxide from a gas mixture containing carbon dioxide. Background technique

[0002] Carbon dioxide is a greenhouse gas. As countries all over the world pay attention to the global warming effect, the emission of carbon dioxide has attracted the attention of the whole world. Known technologies for removing carbon dioxide from mixed gases include chemical absorption technology, physical absorption technology, membrane separation technology, adsorption separation technology and cryogenic separation technology.

[0003] Chemical absorption is a common method for removing carbon dioxide. The early chemical absorption methods used to separate carbon dioxide were the hot potash method and the alcohol amine method. Yet, because the heat potash absorption rate of single component is slower, those skilled in the art have developed the heat potas...
