Its crystal structure comprises silicon oxide tetrahedron and aluminum oxide tetrahedron, which have high chemical and thermal stability. The chemical composition and structure of the TRDN-3 molecular sieve make it have good adsorption and denitration performance.

Pore structure and adsorption properties

TRDN-3 molecular sieve adsorbent for flue gas denitrification has an ordered pore structure and a large specific surface area, which makes it have high adsorption performance. The diameter of the pore and the size and distribution of the specific surface area can be adjusted by preparation conditions to make it suitable for denitration treatment under different flue gas conditions. The pore structure and specific surface area of TRDN-3 molecular sieve adsorbent enable it to effectively adsorb nitrogen oxides (NOx) in flue gas and reduce its emission concentration.

Adsorption kinetics and reaction mechanism

The adsorption kinetics and reaction mechanism of TRDN-3 molecular sieve adsorbent for flue gas denitrification are essential to study its adsorption properties. The results show that the adsorption of NOx by TRDN-3 molecular sieve mainly occurs in the pores and is realized through ion exchange and chemical reactions.

Regeneration and recycling

TRDN-3 flue gas denitrification molecular sieve adsorbent has good regeneration performance and can be reused after regeneration treatment to achieve recycling. Regeneration treatment is to desorb the NOx adsorbed on the surface of the molecular sieve through high-temperature reduction or oxidation and restore its adsorption performance. In the regeneration process, attention should be paid to controlling parameters such as temperature, atmosphere and time to ensure that the adsorption performance of the molecular sieve is not affected.

These properties make it suitable for denitrification under various flue gas conditions, including flue gas with high humidity and high dust content.

Production Method of TRDN-3 Molecular Sieve Adsorbent For Flue Gas Denitration:

Raw material preparation

The raw materials for producing TRDN-3 flue gas denitrification molecular sieve adsorbent mainly include silicate, aluminate, carbonate, etc. A certain proportion and particle size must be used to prepare these raw materials to provide sufficient chemical composition and physical properties to ensure the synthesis and performance of molecular sieves.

Synthetic reaction

The synthesis reaction is critical in producing TRDN-3 flue gas denitrification molecular sieve adsorbent. The reaction combines silicate, aluminate, carbonate and other raw materials under high temperature and pressure. By controlling the reaction temperature, pressure, raw material ratio and other conditions, the chemical reaction of silicon, aluminum, sodium, calcium and other elements is promoted to generate a TRDN-3 molecular sieve with specific pore structure and performance.

In the synthetic reaction process, it is necessary to strictly control the reaction conditions, such as temperature, pressure, pH value, etc. The change in these conditions will affect the crystal structure and molecular sieve properties. To obtain a TRDN-3 molecular sieve with excellent performance, it is necessary to optimize the reaction conditions and production process.

Crystallization treatment

Crystallization treatment is another critical step in producing TRDN-3 flue gas denitrification molecular sieve adsorbent. The treatment is to make the crystal structure of the molecular sieve more complete, orderly and stable by controlling the crystallization time and the type and dosage of the crystallization agent under specific temperature and humidity conditions.

Crystallization treatment can improve the crystal structure and thermal stability of the TRDN-3 molecular sieve and its adsorption and denitrification properties. In the process of crystallization treatment, selecting the appropriate crystallization agent and controlling the crystallization time and temperature is necessary to ensure that the TRDN-3 molecular sieve performs well.

Drying and grinding

Drying and grinding are the last steps in producing TRDN-3 flue gas denitrification molecular sieve adsorbent. This step is mainly to dry and grind the synthesized wet molecular sieve to remove its moisture and other impurities to obtain a dry molecular sieve adsorbent with the desired particle size and shape.

In the drying process, it is necessary to choose the appropriate drying method and control the drying temperature and time to avoid the effect of the crystal structure and properties of the molecular sieve. Grinding is done to obtain a molecular sieve adsorbent with the desired particle size and shape, improving the quality of its specific surface area and pore structure. During the grinding process, attention should be paid to controlling the grinding time and particle size distribution to avoid the molecular sieve's structural damage and performance degradation caused by excessive grinding.

Packaging and storage

TRDN-3 flue gas denitrification molecular sieve adsorbent production needs to be packaged and stored. The packaging protects the molecular sieve from the external environment and extends its storage and service life. When storing, attention should be paid to controlling the temperature and humidity to avoid moisture, deterioration or performance degradation of the molecular sieve.

Regeneration and recycling

TRDN-3 flue gas denitrification molecular sieve adsorbent has good regeneration performance and can be reused after regeneration treatment to achieve recycling. The NOx adsorbed on the surface of the molecular sieve can be desorbed by high-temperature reduction or oxidation to restore its adsorption performance. In the regeneration process, attention should be paid to controlling parameters such as temperature, atmosphere and time to ensure that the adsorption performance of the molecular sieve is not affected.
