Applicants have synthesized a new aluminosilicate zeolite identified as UZM- 4. This new zeolite has the BPH morphology and is structurally related to zeoli te Q. UZM-4 has en empirical formula of Mmn+Rrp+AI1-xExSiyOz where M is an alka li or alkaline earth metal ion, R can be a quaternary ammonium ion and E can be gallium, iron, boron, chromium, indium and mixtures thereof. The Si/AI ratio can range from 1.5 to 4.0. The zeolite can be used in various hydrocarbon conversion processes such as isomerization of alkylaromatic hydrocarbons.</S DOAB> |
