<p>Applicants have synthesized a new aluminosilicate zeolite identified as UZM-4. This new zeolite has the BPH morphology and is structurally related to zeolite Q. UZM-4 has en empirical formula of Mmn+Rrp+AI1-xExSiyOz where M is an alkali 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.</p> |
