| 简介 |
A new family of crystalline aluminosilicate zeolites has been synthesized and designated as UZM-54. These zeolites are represented by the empirical formula :
[in-line-formulae]Mmn+R1 r1p1+R2 r2p2+Al1-xExSiyOz [/in-line-formulae]
where M is an alkali, alkaline earth, or rare earth metal such as sodium or strontium, R1 and R2 are organoammonium cation and E is a framework element such as gallium, iron, boron, or indium. These zeolites are characterized by unique x-ray diffraction patterns, high meso-surface areas and low Si/Al2 ratios and have catalytic properties for carrying out various hydrocarbon conversion processes. |
