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 ...
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 ...
EU-1 zeolite was firstly synthesized in non-spontaneous nucleation system through adding seed solution which was prepared by ourselves.The sample was characterized by means of XRD,SEM and IR.By investigating the effect of water dosage,n(SiO2)/n(Al2O3),n(Na2O)/n(SiO2),crystallizing temperature...
Quasi-solid state synthesis of EU-1 zeolite and its catalytic properties for the isomerization of C_8 aromatics properties were tuned through careful modification of the acidity of EU-1 zeolites and metal-doping of the catalyst.It was shown that EU-1 was an ... G Peng,X Li,Z Shang,.....
