摘　　要：归纳分析了燃煤电厂减排CO2的途径,以煤气化为核心的多联产系统具有提高燃煤利用效率和减排CO2的最大潜力。CO2的分离是未来零排放火电厂所面临的主要挑战之一,在CO2的各分离技术中,膜分离法对电厂效率影响最小。无机膜在涉及高温的分离过程中具有有机高分子膜所无法比拟的优势,为使回收的CO2达到理想的纯度,一方面应开发性能更好的无机膜材料,另一方面还应把膜法和其它有关分离技术进行优化集成。：The approaches of CO2 sequestration from fossil fuel power plants were summed up and analyzed. Multi-cogeneration system as the kernel with coal gasification possesses the maximal potential of improving coal utilization efficiency and CO2 sequestration. CO2 separation is one of the primary challenges of fossil fuel power plants in achieving no discharge in future. In all of the CO2 separation technologies, membrane separation has the minimal influence on the efficiency of power plants. In high temperature separations, inorgamc membranes possess me advantages that organic membranes can not be competed. In order to obtain CO2 with perfect purity, on the one hand, it should develop inorganic membrane materials with better capability, and it should integrate membranes with other separation technologies on the other hand.
