MOLECULAR SIEVE SSZ-116, ITS SYNTHESIS AND USE
A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-116, is provided. SSZ-116 can be synthesized using 3-[(3,5-di-tert-butylphenyl)methyl]-1,2-dimethyl-1H-imidazolium cations as a structure directing agent. SSZ-116 may be used in organic compound conversion reactions and/or sorptive processes.

Zeolite with tuned aluminum content and mesoporosity
Compositions and methods for preparing mesoporous and/or mesostructured materials from low SAR zeolites are provided herewith. In particular, methods are provided that involve: (a) providing a low SAR zeolite, (b) optionally subjecting the low SAR zeolite to an acid framework modification, and (c) subjecting the framework-modified zeolite to a mesopore formation treatment. The resulting mesoporous zeolites can have bi-modal mesoporosity and higher aluminum contents relative to existing mesoporous zeolites.

HETEROATOM SUBSTITUTED ZEOLITES
The invention provides methods for completely removing aluminum from existing zeolite frameworks that have been previously considered unalterable due to their small pore sizes and stable crystal structures. Consequently, new combinations of metal atoms and zeolite structures can now be made using the methods disclosed herein. Metal atoms that have useful properties for catalysis and adsorption have been integrated into zeolite structures that provide advantageous size selection or solvation properties to increase rates, conversions, and yields of catalytic processes. The disclosed catalysts and methods reduce the cost of synthesizing useful materials and zeolite structures with compositions of matter that have not been reported.
SCR catalyst
A copper-CHA zeolite catalyst for SCR of NO.sub.x is disclosed.
