摘要
利用浸渍法将[NH3P-mim][BF4]和[MEA]L两种离子液体负载到AC、Al2O3和MCM-41上,考察了对CO2的吸附性能,确定了[NH3P-mim][BF4]/AC对CO2的吸附性能最优。并对[NH3P-mim][BF4]/AC考察了不同负载量、不同温度下对CO2的吸附性能,确定了固载离子液体对CO2的吸附容量随着负载量的增加而增加,且30℃是固载离子液体吸附CO2的最佳温度,吸附容量达到0.063mmol CO2·(g SILP)-1。对[NH3Pmim][BF4]/AC进行红外和热重两种表征,确定了负载离子液体的结构以及在50℃以下优良的热稳定性。
Two kinds of ionic liquids([NH3 P-mim][BF4 ]and[MEA]L)were supported to AC,Al2 O3 and MCM-41 by soaking method.[NH3 P-mim][BF4 ]/AC was confirmed to have the better CO2 adsorption capacity.Using[NH3 P-mim][BF4 ]/AC,CO2 adsorption capacity was tested under the condition of different amount of supported ionic liquids and different temperature.The results show that CO2 adsorption capacity increases with the amount of supported ionic liquids increasing,and 30℃ was the optimum temperature,with an CO2 adsorption capacity of 0.063mmol CO2·(g SILP)-1.The structure of the[NH3 P-mim][BF4 ]/AC was confirmed by FT-IR and thermogravimetry characterization,the latter shows that it has excellent thermostability wthin below 50℃.
