Aluminosilicate zeolite PST-7 and its manufacturing process

Zeolites with different crystal structures

This technology relates to a method of manufacturing aluminosilicate zeolite with a UFI structure.

Since zeolites can have different properties depending on their framework composition and crystal structure, the development of UZM-5 zeolite with various framework compositions and different crystal structures is required, and this technology proposes an aluminosilicate zeolite with a new composition having a UFI structure.

This technology By using 1-Benzyl-2,3-dimethylimidazolium cation as an organic structure-inducing molecule, PST-7 zeolite with UFI structure with new framework composition, crystal shape and size can be created, and it becomes a new zeolite with different physicochemical and catalytic properties.

Key Features:

• The Si/Al ratio is in the range of 7.5 to 50, preferably in the range of 10 to 25.
• UFI-structured aluminosilicate zeolites form rectangular crystal structures with a thickness of 0.3 μm or more.
• 1,2-Dimethyl-3-(2-fluorobenzyl)imidazolium cations are used as organic structure-directing molecules.
• Synthesized by converting to a hydroxide form using synthetic resins.
