AI Technical Summary
Technical Problem
There is a need for alternative, less expensive structure directing agents for the synthesis of zeolites of the SSZ-26/33 family of zeolites.
Method used
The use of 1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane cations as a structure directing agent in the synthesis of SSZ-26/33 family zeolites, along with a reaction mixture comprising silica, aluminum oxide, a Group 1 or Group 2 metal, hydroxide ions, seed crystals of zeolite Al-SSZ-33, and crystallization conditions to form zeolite crystals.
Benefits of technology
The method enables the synthesis of SSZ-26/33 family zeolites with 1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane cations retained in the pores, facilitating efficient crystallization and providing a cost-effective alternative to existing agents.
