摘要： The present invention is directed to a method of preparing a molecular sieve of SWY framework type, denominated STA-30. STA-30 is synthesized using 1,4-diazabicyclo[2.2.2]octane, 1-azabicyclo[2.2.2]octane derivates and combinations thereof as structure directing agents. The resulting molecular sieve is useful as catalysts, particularly when used in combination with exchanged transition metal(s) for the Selective Catalytic Reduction (SCR) of NO

摘要： 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).
