Zeolite molecular sieve carrier

Zeolite adsorbent products include microporous adsorbents and mesoporous adsorbents.

(1) Molecular sieves with a pore size below 2 nm are microporous molecular sieves, while those with a pore size between 2-50 nm are mesoporous Jiangxi molecular sieves (those with a pore size above 50 nm are macroporous molecular sieves). Mesoporous molecular sieves have the characteristics of * specific surface area, regular and ordered pore structure, narrow pore size distribution, and continuously adjustable pore size, which make them play an important role in the adsorption, separation, and catalytic reactions of large molecules that are difficult to achieve with many microporous molecular sieves.

(2) Therefore, when selecting, molecular sieve materials with different properties and pore sizes should be configured according to the different components of organic waste gas. Honeycomb block zeolite molecular sieve can achieve targeted organic waste gas treatment, meet design requirements, and meet emission standards.

Zeolite molecular sieve carrierZeolite molecular sieve hasstrongThe reason why it has strong adsorption performance is due to the "surface force" generated by the molecular gravity acting on the solid surface. When the fluid flows through, some molecules in the fluid collide with the adsorbent surface due to irregular motion, resulting in molecular concentration on the surface and reducing the number of such molecules in the fluid for the purpose of separation and removal. Due to the fact that adsorption does not undergo chemical changes, as long as the molecules concentrated on the surface are driven away, zeolite molecular sieves will have adsorption ability again. This process is the reverse process of adsorption, known as the desorption or regeneration process.

Zeolite molecular sieve carrierThe adsorption of zeolite molecular sieves is a physical process. The main reason for adsorption is the "surface force" generated by the molecular gravity acting on the solid surface. When the fluid flows through, some molecules in the fluid collide with the adsorbent surface due to irregular motion, resulting in molecular concentration on the surface and reducing the number of such molecules in the fluid, achieving the purpose of separation and removal.

Most zeolite molecular sieves have strong acid centers on their surfaces, and there is a strong Coulomb field in the crystal pores that polarizes them. These characteristics make it an excellent catalyst. Multiphase catalytic reactions are carried out on solid catalysts, and the catalytic activity is related to the size of the catalyst's crystal pores. When zeolite molecular sieve is used as a catalyst or catalyst carrier, the catalytic reaction is controlled by the pore size of zeolite molecular sieve. The size and shape of crystal pores and pore channels can play a selective role in catalytic reactions. Under normal reaction conditions, zeolite molecular sieves play a dominant role in the reaction direction and exhibit shape selective catalytic performance, which gives zeolite molecular sieves strong vitality as a new catalytic material.
