摘要
综述了近年分子筛的脱硫脱氮机理及动力学,从表面酸性和孔结构两方面评述了ZSM-5分子筛的改性。重点综述了基于ZSM-5的杂原子分子筛、分子筛膜、纳米分子筛的研究动态和发展趋势,指出了研究应用中存在的问题以及今后的研究方向。
This review introduced the application on desulfurization and denitrification mechanistic and reaction kinetics.Some kinds of modification technology on ZSM-5 zeolite were discussed from the zeolite surface acidity and pore structure.The focus in the paper was on the recent advance and trend of development including hetero-atom molecular sieve,zeolite membrane and nano-zeolite based on ZSM-5.And their advantages as well as problems to be solved were also proposed here.
