Abstract

Abstract: Two kinds of ionic liquids ([NH₃P-mim][BF₄] and [MEA]L) were supported to AC, Al₂O₃ and MCM-41 by soaking method. [NH₃P-mim][BF₄]/AC was confirmed to have the better CO₂ adsorption capacity. Using [NH₃P-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 0.063 mmol CO₂·(g SILP)^-1. The structure of the [NH₃P-mim][BF₄]/AC was confirmed by FT-IR and thermogravimetry characterization, the latter shows that it has excellent thermostability wthin below 50℃.

Key words: supported ionic liquid, CO₂, adsorption capacity

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0.063 mmol CO₂·(g SILP)^-1。对[NH₃P-mim][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。
