Molecular sieves comprising intergrowths of cha and aft having an “sfw-GME tail”, at least one structure directing agent (SDA) within the framework of the molecular sieve, an intergrowth of CHA and GME framework structures, cha cavities, and aft cavities are described. A first SDA comprising either an N,N-dimethyl-3,5-dimethylpiperidinium cation or a N,N-diethyl-2,6-dimethylpiperidinium cation is required. A second SDA, which can further be present, is a CHA or an SFW generating cation. The amount of the second SDA-2 used can change the proportion of the components in the cha-aft-“sfw-GME tail”. Activated molecular sieves formed from SDA containing molecular sieves are also described. Compositions for preparing these molecular sieves are described. Methods of preparing a SDA containing JMZ-11, an activated JMZ-11, and metal containing activated JMZ-11 are described. Methods of using activated JMZ-11 and metal containing activated JMZ-11 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

A method of preparing a mesoporous Fe—Cu—SSZ-13 molecular sieve includes activating an aluminum source, a silicon source, an iron source and a copper source respectively; mixing the activated minerals with sodium hydroxide, water and a seed crystal at 25-90° C., while controlling feeding amounts of respective raw materials so that molar ratios of respective materials in a synthesis system are as follows: SiO.sub.2/Al.sub.2O.sub.3=10-100, SiO.sub.2/Fe.sub.2O.sub.3=30-3000, SiO.sub.2/CuO=1-100, Na.sub.2O/SiO.sub.2=0.1-0.5, H.sub.2O/SiO.sub.2=10-50, template/SiO.sub.2=0.01-0.5; adding an acid source to adjust pH of the system for first aging; and adding the acid source again to adjust the pH of the system for second aging to obtain aged gel; pouring an aged mixture into a kettle; cooling a crystallized product and filtering to remove a liquor; washing a filter cake; drying to obtain a solid; performing ion exchange; and filtering, washing and drying the solid to obtain powder; and placing the powder in a muffle furnace.

A molecular sieve has a silica/alumina molar ratio of 100-300, and has a mesopore structure. One closed hysteresis loop appears in the range of P/P.sub.0=0.4-0.99 in the low temperature nitrogen gas adsorption-desorption curve, and the starting location of the closed hysteresis loop is in the range of P/P.sub.0=0.4-0.7. The catalyst formed from the molecular sieve as a solid acid not only has a good capacity of isomerization to reduce the freezing point, but also can produce a high yield of the product with a lower pour point. The process for preparing the catalyst involves steps including crystallization, filtration, calcination, and hydrothermal treatment.

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.
