METHOD FOR PREPARING ZEOLITE OF MTT STRUCTURE TYPE Russian patent published in 2021 - IPC C01B39/04 

FIELD: technological processes.

SUBSTANCE: invention relates to methods of producing a molecular sieve of the MTT structure type. Method of producing the zeolite with a MTT structure type involves preparation of a reaction mixture containing sodium or potassium cations, sources of aluminium oxide (Al₂O₃) and silicon oxide (SiO₂), water and templates of N-methylpyrrolidone. Mixture of solutions is prepared proceeding from observance of molar ratio of used components in hydrogel: SiO₂/Al₂O₃ = 51–101, H₂O/SiO₂ = 25–50, (Na⁺ or K⁺)/SiO₂ from 0.31 to 0.7, templates/SiO₂ from 0.2 to 0.7, followed by holding said mixture in a sealed reactor.

EFFECT: production of MTT zeolite with high content of aluminum SiO₂/Al₂O₃ from 30 to 60 and volume of micropores 0_06–0_09 cm³/g.
