-
摘要: 九十年代初新发展的超大孔分子筛MCM-41,它的孔径远远超过目前小于1.2mm的微孔分子筛如X,Y,,丝光沸石和ZSM-5沸石。由于它的均匀大孔结构和较好的酸性可以应用于重油加工和大分子 细化工反应,是当前国内外沸石研究热点课题。Abstract: The pore diameter of MCM- 41 (a kind of new super -marroporous molecular sieve developed in early 90' s) is 3. 5nm and faraway surpass those of present microporous molecular sieves(< 1. 2nm)such as X,Y, mordenite and ZSM - 5 zeolite etc.It can be used in
