Abstract: The present invention is directed to an alumino-borosilicate SSZ-57 zeolite having enhanced large pore selectivity. The alumino-borosilicate SSZ-57 zeolite of the present invention is characterized as having substantially all of its aluminum atoms located within regions of the zeolite structure which form the 12 ring channels.

Abstract: A new crystalline zinc (silico)aluminophosphate molecular sieve designated SSZ-90 is disclosed. SSZ-90 is isostructural with the DFO framework type and is synthesized using an ionic liquid as both the solvent and the structure directing agent. The ionic liquid [Q+A−] comprises a cation (Q+) selected from the group consisting of 1,3-diisopropylimidazolium, 1,3-diisobutylimidazolium, and 1-isopropyl-3-isobutylimidazolium and an anion (A−) which is not detrimental to the formation of the molecular sieve.
