促进CO传递的离子液体支撑液膜的制备及其机理研究

With the development of C1-Chemistry, the need of carbon monoxide is increasingly. Some exhaust gases from industries contain carbon monoxide, which is harmful to human beings. So the recovery and the reuse of such waste gases have become a very important task. Compared with conventional separation techniques, membranes offer a great potential. In this project, it tends to design new ionic liquid system containing metal carrier according to the carbon monoxide complexation, and prepare supported ionic liquid membrane for carbon monoxide separation from gas mixtures containing N2. According to this project, it can propose a new route to prepare CO separation membrane with good stability, high permeability and selectivity. Simultaneously, it can provide theoretical and experimental foundation for the use of supported ionic liquid membrane.

随着碳一化工的迅速发展，高纯度CO的需求日益增加；另一方面不少工业排放气中含有CO，对环境构成了严重威胁，因此分离和净化CO具有重要的意义。与传统的分离过程相比，膜法分离技术被认为是最具吸引力的替换过程。本项目以工业过程排放的尾气如高炉气、转炉气、电石炉气中的CO分离纯化为背景，选取CO/N2分离体系为研究对象，以CO与金属离子之间的络合作用为促进传递机理，设计新的含有金属离子载体的离子液体膜体系，开发适合CO分离与纯化的离子液体支撑液膜。通过本项目的实施不仅为制备高稳定性、高气体渗透性和分离性能的CO分离膜提供了一条新的途径，同时也为离子液体支撑液膜的应用提供实验基础和理论依据。
