Abstract: A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-114, is provided. SSZ-114 can be synthesized by treating an aluminogermanosilicate molecular sieve of CTH framework topology with water or an aqueous solution of a mineral acid under conditions sufficient to degermanate at least a portion of aluminogermanosilicate molecular sieve to form a degermanated molecular sieve and calcining the degermanated molecular sieve under conditions sufficient to convert the degermanated molecular sieve to SSZ-114. Molecular sieve SSZ-114 may be used in organic compound conversion reactions and/or sorptive processes.

Abstract: The present disclosure is directed to novel germanosilicate compositions and methods of producing the same. In particular, this disclosure describes an array of transformations originating from the extra-large-pore crystalline germanosilicate compositions, designated CIT-13, possessing 10- and 14-membered rings. Included among the new materials are the new phyllosilicate compositions, designated CIT-13P, new crystalline microporous germanosilicates including high silica versions of CIT-5 and CIT-13, with and without added metal oxides, and new germanosilicate compounds designated CIT-14 and CIT-15. The disclosure also describes methods of preparing these new germanosilicate compositions as well as the compositions themselves.

Abstract: Uses for a family of new crystalline molecular sieves designated SSZ-91 are disclosed. Molecular sieve SSZ-91 is structurally similar to sieves falling within the ZSM-48 family of molecular sieves, and is characterized as: (1) having a low degree of faulting, (2) a low aspect ratio that inhibits hydrocracking as compared to conventional ZSM-48 materials having an aspect ratio of greater than 8, and (3) is substantially phase pure.
