PROCESS AND SYSTEM FOR CAPTURE OF CARBON DIOXIDE

A process for absorbing carbon dioxide from a gas stream containing carbon dioxide. The process comprises contacting the gas stream with an aqueous composition comprising a substituted heteroaromaticcompound comprising a six-membered heteroaromatic ring comprising from 1 to 3 nitrogen atoms in the heteroaromatic ring and at least one substituent wherein at least one of the substituents is of formula -R1NH2 wherein R1 is selected from the group consisting of C1 to C6alkylene and ethers of formula -R2-O-R3-, wherein R2 and R3 are C1 to C3 alkylene. 一种用于从包含二氧化碳的气流中吸收二氧化碳的工艺，所述工艺包括使气流与包含被取代的杂芳族化合物的含水组合物接触，所述杂芳族化合物包含六元杂芳环，所述六元杂芳环包含杂芳环中的从1个至3个氮原子和至少一个取代基，其中取代基中的至少一个具有式-RNH，其中R选自由以下组成的组：C至C亚烷基和式-R-O-R-的醚，其中R和R是C至C亚烷基。
