摘要:
针对目前聚离子液体存在的对CO2的吸收量低且吸收和解吸速率慢等问题,采用交联剂并分别结合不同干燥方法(冷冻干燥、超临界CO2干燥、普通干燥)合成了一种交联型季铵盐类聚离子液体,进而采用高压石英弹簧法测定其对CO2的吸收能力.研究结果表明,采用冷冻干燥法制得的聚离子液体相对结晶度低,具有较高的CO2吸收量,在298.2 K、0.21 MPa下对CO2的吸收量最高达0.024 g/g,而在5.0 MPa下高达0.127 g/g.在298.2 K下5.0 MPa的高压合成气(H2/CO/CO2)中对CO2的变压吸收分离结果显示,该聚离子液体具有性能稳定、吸收和解吸速率快及对CO2选择性高等优点.
Abstract:
Carbon dioxide(CO2)capture has attracted extensive attention in recent years.Among the various capture media, polymeric ionic liquids(PILs)have caused concern for its better CO2 absorption and desorption capacity.However,the CO2 absorption in PILs is still relatively low in the literature reported.In this work,a quaternary ammonium based crosslinked PIL was synthesized and dried by different drying methods,and the high-pressure quartz spring method was employed to study its absorption of CO2.Results showed that the crosslinked PIL from freeze dryinghad low crystallinityand high CO2 absorption, and its CO2 absorptionwas 0.024 g/g at 298.2 K and 0.21 MPa,while it was up to 0.127 g/g at 298.2 K and 5.0 MPa.At 298.2 K and 5.0 MPa,the pressure swing absorption process was implemented for separation of CO2 from the high-pressure syngas system,revealing efficient separation of CO2 from H2/CO/CO2.And the crosslinked PIL also showed its excellent stability,fast absorption and desorption rate and high selectivity for CO2.
