ZSM(Zeolic socony Mobil)系列沸石分子筛是从1968年开始被美国莫比尔(Mobil)公司所开发。这种新型结晶硅铝酸盐沸石,作为分子筛催化剂,在催化活性、选择性、稳定性等方面具有比其它型号沸石更好的性能。目前已从 ZSM—1发展到 ZSM—48。每一品种都有其特征 X—射线衍射图谱(参看附录表1,2,3,4).ZSM 系列沸石大都有较高的硅铝比,其晶体结构与 A、X、Y、M 型沸石不同,它 ZSM (Zeolic socony Mobil) series zeolite molecular sieve was from the United States in the beginning of 1968 developed by Mobil Corporation (Mobil). The new crystalline aluminosilicate zeolite, as a zeolite catalyst, has better performance than other zeolites in terms of catalytic activity, selectivity, stability and the like. Has now developed from ZSM-1 to ZSM-48. Each species has its own characteristic X-ray diffraction pattern (see appendix Table 1, 2, 3, 4) .ZSM series of zeolites mostly have a higher ratio of Si to Al, the crystal structure and A, X, Y, M zeolite Different, it
