离子液体1-氨丙基-3-甲基咪唑溴盐对CO2吸收的应用研究
Study of ionic liquid [1-NH2-C3 mim] [Br] for CO2 absorption
摘要
Abstract
The influence of systematic temperature,initial pressure and mass fraction of ionic liquid on CO2 absorption with ionic liquid [1-NH2-C3mim] [Br] was studied by static absorption method.The optimized absorption process conditions are as follows:mass fraction of ionic liquid ([1-NH2-C3mim] [Br]) is 50％,systematic temperature is 303.15 K and initial pressure is 165.64 kPa.Meanwhile,“ two-stage” vacuum regeneration period for absorbent was tried.The regeneration temperature in the first stage is 321.15 K,30 min;that in the second stage is 343.15 K,only 10 min.The result shows that the effect of ionic liquid [1-NH2-C3mim][Br] for CO2 absorption is good,which can be reused due to its steady absorption properties after regenerated.关键词
