Abstract: Coal is the main source of energy in China. Sulfur dioxide (SO2)，carbon dioxide (CO2)，nitric oxide (NO) and other pollutants emitted from coal combustion affect the environment and human health. The status of zeolite and modified zeolite adsorption for desulfurization，decarbonization，denitrification and simultaneous desulfurization and denitrification technologies were summarized in this paper. The influencing factors in these removal processes were analyzed，including the effects of temperature and modification on desulfurization，the effects of pressure，temperature and modification on decarbonization，the effects of O2，water，modification on denitrification，and the effects of concentration and sulfur resistance on simultaneous desulfurization and denitrification. The development trend of simultaneous removing three gases above was also prospected.

Key words: zeolites, adsorption, desulfurization, denitrification, decarbonization, zeolites, adsorption, desulfurization, denitrification, decarbonization

摘要： 煤炭是我国主要的能源，但燃煤烟气中二氧化硫（SO2）、二氧化碳（CO2）、一氧化氮（NO）等污染物会对环境和人类健康造成不利的影响。本文综述了分子筛及改性分子筛吸附脱硫、脱碳、脱硝技术和同时脱硫脱硝技术的现状；分析了温度、改性对脱硫的影响，压力、温度、改性对脱碳的影响，O2、水分、改性对脱硝的影响以及浓度、抗硫性能对脱硫脱硝的影响；并对同时脱除上述3种气体的发展趋势进行了展望，为多组分气体共吸附技术及燃煤烟气硫碳硝同时脱除的工业化应用提供理论依据和方法。
