Product Description

Solid Catalyst Molecular Sieve ZSM-600 

Introduction: 

The crystal structure of ZSM-5 molecular sieve is composed of silicon (aluminum) oxygen tetrahedron. The silicon (aluminum) oxygen tetrahedron forms a five-membered silicon (aluminum) ring through a common vertex oxygen bridge. Eight such five-membered rings form the basic structural unit of ZSM-5 molecular sieve. The pore structure of ZSM-5 molecular sieve is composed of straight cylindrical channels with an elliptical cross-section (channel size: 0.54×0.56nm) and approximately circular Z-shaped channels (channel size: 0.52×0.58nm). The size of the channel intersection is 0.9nm.
ZSM-5 molecular sieve has a regular pore structure, medium and large specific surface area, high hydrothermal stability, good ion exchange performance and rich and adjustable surface properties. Its unique pore structure not only provides spatial confinement for shape-selective catalysis, but also provides abundant entry and exit channels for reactants and products. It also provides opportunities for the preparation of industrial catalysts with high selectivity, high activity, and strong resistance to coking and deactivation. The basis of crystal structure. As a result, it has become one of the most important materials in shape-selective catalytic reactions in the petroleum industry. ZSM-5 molecular sieve has also been widely used in fields such as fine chemicals and environmental protection. The application fields of ZSM-5 molecular sieve products with different silicon to aluminum ratios are also different.

 ZSM-5 molecular sieve characteristics:
1.Thermal stability: ZSM-5 molecular sieve has excellent thermal stability. This characteristic is due to the structurally stable five-membered ring in its skeleton and the high silicon content of the skeleton. ZSM-5 molecular sieve is one of the known molecular sieves with the highest thermal and temperature properties. Therefore it is particularly suitable for use in high temperature processes. For example, when used as a hydrocarbon cracking catalyst, it can withstand high temperatures during catalyst regeneration.
2. Acid resistance: ZSM-5 molecular sieve has good acid resistance and can withstand various acids except hy drofluoric acid.
3. Hydrothermal stability: When molecular sieves encounter high-temperature water vapor, their structures are generally severely damaged, leading to irreversible deactivation. ZSM-5 molecular sieve has excellent hydrothermal stability and can be used as a catalyst for meth anol conversion (water is the main by-product).
4. Hydrophobicity: ZSM-5 molecular sieve has a high silicon-to-aluminum ratio and a small surface charge density. Water is a highly polar molecule, so it is not easily adsorbed by ZSM-5 molecular sieve. Although the diameter of water molecules is smaller than n -hexane, the adsorption capacity of ZSM-5 molecular sieve for n -hexane is generally greater than that of water.
5. Not easy to deposit carbon: The effective shape, size and bending of the pores of ZSM-5 molecular sieve prevent the formation and accumulation of macromolecular condensates. At the same time, there are no cages larger than the pores in the ZSM-5 molecular sieve framework, so the side reactions of condensation are limited, thereby reducing the possibility of carbon deposition on the ZSM-5 molecular sieve catalyst.
6. Excellent shape selectivity: Using ZSM-5 molecular sieve as a catalyst, only molecules smaller than the pore size can enter and exit. The progress of the catalytic reaction is controlled by the pore size of the zeolite. The molecular sieve catalyst affects the size and shape of the reactant and product molecules. Great selectivity.

Scope of application:

1.Mainly used in diesel hydrogen decondensation catalyst and fixed bed catalytic cracking catalyst.
2.The addition of ZSM-5 molecular sieve to the fluidized bed catalytic cracking reaction FCC catalyst has a significant effect on increasing the octane number of gas oline and increasing the olefin content of the gas.
3.As a hydrocarbon cracking catalyst, it can withstand high temperatures during catalyst regeneration.
4.Zeolite ZSM-5 molecular sieve catalyst hasbeen used as the parent of alkylationm, isomeration, aromatization and dewaxing catalysts and so on. 
4.It can be used in the production of ethylbenzene, p -xylene, phe nol, etc.

Our advantage:

The green synthesis process technology of sub-micron ZSM-5 molecular sieve has filled the domestic gap. It has independent intellectual property rights and the overall process equipment technology level is leading in the country.
Technical innovation points:
1. Use a mixture of solid silica gel and liquid water glass as the silicon source to increase the solid content of the slurry and achieve the synthesis of ZSM-5 molecular sieve at high concentration;
2. Use the alkalinity of water glass as the alkali source, without adding other alkaline substances, simplifying the synthesis steps;
3. Dissolve the seed crystal into the water glass solution under heating conditions to form a translucent emulsion (molecular sieve precursor), which increases the crystallization rate and reduces the average particle size of the molecular sieve.

Terms and Conditions:
Keep sealed. This product is non-toxic, but improper use may cause slight irritation to the respiratory tract and eyes, and direct contact may cause skin dryness. It is recommended to wear masks and gloves when using.
