PROCESS FOR SEPARATING CO2 FROM A GASEOUS STREAM

摘要

Process for separating CO2 from a gaseous stream by chemisorption to 1-ethyl-3-methylimidazolium (emim) or 1-propyl-3-methylimidazolium (pmim), characterized in that emim or pmim are present as carboxylate salt and that chemisorption is carried out in the presence of guanidinium acetate or 1-butyl-3-methylimidazolium (bmim) acetate.
