Description

SAPO-34 is a zeolite with a rhombic zeolite like structure, whose skeleton is mainly composed of silicon aluminum phosphate. It has an elliptical CHA cage composed of double hexagonal, eight membered, and four membered rings, as well as a three-dimensional cross pore structure.

SAPO-34 zeolite has extremely high specific surface area, good hydrothermal stability, abundant proton acidity and ion exchange sites, and its unique eight membered ring three-dimensional pore system gives it excellent small molecule shape selective catalytic performance. It is a widely used solid acid catalyst and catalyst carrier.
