Description

Technical Field

[0001] The present invention relates to the technical field of molecular sieves, and in particular to a TON molecular sieve and a preparation method and application thereof, and a TON molecular sieve composition and application thereof. Technical Background

[0002] TON molecular sieve is a mesoporous molecular sieve with one-dimensional elliptical straight pores, with 10-membered ring openings measuring 0.46 x 0.57 nm. Due to its mild acidic properties and steric shape selectivity, ZSM-22 molecular sieves are used in the isomerization of linear alkanes, methanol to olefins, aromatic alkylation, hydrocracking, catalytic dewaxing, and alkane aromatization.

[0003] Molecular sieves with a TON structure include Theta-1, ZSM-22, KZ-2, NU-10, and ISI-1. US Patent 5342596 discloses a method for preparing a molecular sieve named Theta-1. The process uses a halogenated derivative of a nitrogen-containing heterocyclic compound as a template. The synthesis generally requires a dynamic crystallization reactor, and impurities such as ZSM-5 or white silica are easily present in the product. US Patent 4481177 discloses a method for synthesizing ZSM-22 using N-ethylpyrrole bromide as a template. The preparation requires vigorous stirring and has poor synthetic reproducibility. US Patent 4900528 discloses a method for synthesizing a molecular sieve named NU-10, which uses an organic template of the structure L1-(CH2)n-L2, where L1 and L2 are hydroxyl groups and / or amino groups. US Patent 4483835 discloses a molecular sieve named ISI-1, which uses a salt of a derivative of a nitrogen-containing heterocyclic compound as a template. Most of these syntheses need to be carried out under high-speed stirring, otherwise the synthesis is likely to fail. Summary of the Invention
