Abstract: The present invention is directed to a method of preparing a synthetic crystalline material, designated as JMZ-12, with a framework built up by the disorder AEI and CHA structures, substantially free of framework phosphorous and prepared preferably in the absence of halides such as fluoride ions. Such method comprises the step of heating a reaction mixture under crystallization conditions for a sufficient period to form a disordered zeolite having both CHA and AEI topologies, wherein the reaction mixture comprises at least one source of aluminum, at least one source of silicon, a source of alkaline or alkaline-earth cations, and a structure directing agent containing at least one source of quaternary ammonium cations and at least one source of alkyl-substituted piperidinium cations in a molar ratio of 0.20 to about 1.4. The resulting zeolites are useful as catalysts, particularly when used in combination with exchanged transition metal(s) and, optionally, rare earth metal(s).

Abstract: The invention relates to a method of preparing SAPO-56, (AFX) using a lower alkyl amine, preferably trimethylamine, and a 1,4-diazabicyclo [2.2.2]octane derivative, preferably comprising either 1,4-(1,4-diazabicyclo[2.2.2]octane)butyl cations or 1,5-(1,4-diazabicyclo[2.2.2]octane)pentyl cations, as structure directing agents (SDAs). A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide (TBAOH), can be used to control the pH. The invention also relates to SAPO-56 comprising a lower alkyl amine, such as trimethylamine, and a 1,4-diazabicyclo [2.2.2]octane derivative, such as a compound comprising either 1,4-(1,4-diazabicyclo[2.2.2]octane)butyl cations or 1,5-(1,4-diazabicyclo[2.2.2]octane) pentyl cations.

Abstract: STA-19, a molecular sieve having a GME structure and phosphorus in the framework, is described. STA-19AP (as prepared) can have a lower alkyl amine, such as trimethylamine, and olig-(1,4-diazabicyclo[2.2.2]octane)-pentyl dibromide ([DABCO-C5]x where x represents the number of repeating units) or olig-(1,4-diazabicyclo[2.2.2] octane)-hexyl dibromide ([DABCO-C6]x) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide (TBAOH), can be used as a pH modifier for the preparation of SAPO-STA-19. A calcined product, STA-19C, formed from STA-19AP is also described. Methods of preparing STA-19AP, STA-19C and metal containing calcined counterparts of STA-19C are described along with methods of using STA-19C and metal containing calcined counterparts of STA-19C in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

Abstract: 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.
