A new zeolite material designated EU-1 having a molar composition expressed by the formula:\nwherein R is a monovalent cation or '/n of a cation of valency n, X is silicon and/or germanium, Y is one or more of aluminium, iron, gallium or boron, and H20 is water of hydration ...
采用固相原位转化法在HMBr2-Na2O-Al2O3-SiO2-H2O体系中快速合成出高结晶度的EU-1分子筛,晶化时间明显缩短,从水热合成时的168h缩短至28h;考察了水添加量对晶化过程的影响,发现在较低的液固比(n(H2O)∶n(SiO2)=4。 EU-1 zeolite was synthe...
A new zeolite material designated EU-1 having a molar composition expressed by the formula: 0.5 to 1.5 R 2 O:Y 2 O 3 : at least 10 XO 2 :0 to 100 H 2 O wherein R is a monovalent cation or 1 /n of a cation of valency n, X is silicon and/or germanium, Y is one or ...
atoms, at least one matrix and at least one metal from group VIII of the periodic table of the elements, the modified zeolite having a number of hexacoordinated aluminium atoms representing more than 20% by weight of the total number of aluminium atoms present in said modified EU-1 zeolite....

EU-1/MOR 1. TheEU-1/MOR zeolitewas characterized by XRD,IR and SEM. 首次以溴化六甲双铵(HMBr2)为模板剂、丝光沸石(MOR)为晶种,采用预置晶种法在高浓体系中合成复合分子筛EU-1/MOR。 更多例句>> 2) EU-1/MOR composite molecular sieve
如Lianhui Ding等在“Nanocrystalline zeolite EU-1:The effect of template agent on crystal size”(Materials Research Bulletin,2007,42:584–590)的文章中,提到了一种纳米EU-1分子筛的合成方法。该合成方法中所用的铝源就是纯金属铝,金属铝必须在四乙基氢氧化铵溶液中经过预先溶解,再经过成胶,最后水热晶化...
