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 4Ø The zeolite can be used in various hydrocarbon conversion processes such as isomerization of alkylaromatic hydrocarbons.
On a synthétisé un nouvel aluminosilicate appelé UZM-4. Cette nouvelle zéolite présente la morphologie BPH et est structurellement associée à la zéolite Q. UZM-4 est de formule empirique M¿m??n+¿R¿r??p+¿AI¿1-x?E¿x?Si¿y?O¿z? où M représente un ion de métal alcalino-terreux, R peut être un ion d'ammonium quaternaire et E peut représenter gallium, fer, bore, chrome, indium et des mélanges de ces métaux. Le rapport Si/AI peut varier de 1,5 à 4,0. La zéolite peut être utilisée dans de nombreux procédés de conversion d'hydrocarbures tels que l'isomérisation des hydrocarbures alkylaromatiques.
