Structural characteristics of TRDN-1 molecular sieve catalyst

TRDN-1 molecular sieve catalyst has a unique structure, mainly consisting of molecular sieve, active component and carrier. The molecular sieve is the core part of the catalyst, which has a highly ordered pore structure and good adsorption performance. The active group is a catalytic active metal or metal oxide loaded on the molecular sieve, such as platinum, palladium, etc. The carrier supports and disperses the active components; the commonly used carriers are aluminium oxide, silicon oxide, and so on.

The catalytic performance of TRDN-1 molecular sieve catalyst

TRDN-1 molecular sieve catalyst showed excellent catalytic performance in the denitrification process of DSL vehicle exhaust gas. First, it has a high denitrification efficiency, which can reduce the concentration of NOx in the exhaust gas to a lower level. Secondly, it is resistant to sulfur poisoning and can maintain a high denitrification efficiency even in an environment containing harmful substances such as sulfides. In addition, the TRDN-1 molecular sieve catalyst also has lower energy and catalyst consumption, reducing the cost of denitrification.

The catalytic mechanism of TRDN-1 molecular sieve catalyst

The catalytic mechanism of TRDN-1 molecular sieve catalyst in the denitrification process of DSL vehicle exhaust mainly includes two aspects: adsorption and a catalytic reaction. First, the molecular sieve's pore structure can effectively adsorb NOx gas in the tail gas and transfer it from the gas phase to the solid phase. The active component then catalyzes the reaction with NOx on the molecular sieve, converting it into harmless nitrogen and water vapour. In this process, the TRDN-1 molecular sieve catalyst can achieve highly selective denitration and avoid side reactions.

Production Method of TRDN-1 Molecular Sieve Stimulant for Denitration of Exhaust Gas of DSL Cars:

Preparation of raw materials: TRDN-1 molecular sieve catalysts include niobium, carbon, chromium, etc. These raw materials need to ensure the purity and granularity of the production requirements and that the supply of these raw materials is sufficient and affordable.

Melting: Put the mixed raw materials into the melting furnace for melting to form an alloy melt. It is necessary to control temperature and time in the melting process to ensure the uniformity and stability of the alloy melt composition.

Pouring and cooling: The alloy melt is poured into the cooling mould and quickly cooled by the cooling equipment to form the alloy powder. It is necessary to control the pouring speed and temperature during the pouring process to avoid the problem of pouring defects and cooling inequality.

Screening and packaging: The formed alloy powder is screened, unqualified particles are removed, and packaged for easy transportation and use. In the screening process, it is necessary to select the appropriate screen and screening equipment to ensure that the particle size and shape of the alloy powder meet the requirements.

Activation treatment: The alloy powder is activated at a specific temperature and atmosphere to activate the active component of the catalyst and improve its catalytic performance. 

Surface treatment: After activation, the catalyst is surface treated to improve its anti-toxicity and anti-wear properties. Surface treatment usually includes coating treatment, ion exchange and other methods, which can enhance the durability and stability of the catalyst.

Test and inspection: Performance test and inspection of the produced TRDN-1 molecular sieve catalyst, including denitrification efficiency, anti-sulfur poisoning performance, stability and other aspects of the test. Only catalysts that meet the performance requirements can be put into use.

Storage and transportation: For the storage and transportation of the generated TRDN-1 molecular sieve catalyst, choosing the appropriate packaging and storage method is necessary to ensure that the catalyst will not be damaged or contaminated during transportation and storage.

Applications of TRDN-1 Molecular Sieve Stimulant for Denitration of Exhaust Gas of DSL Cars:

Diesel vehicle exhaust denitrification

TRDN-1 molecular sieve catalyst is the most widely used in diesel vehicle tail gas denitrification. It can effectively reduce the NOx concentration in the exhaust gas of diesel vehicles and has high denitrification efficiency and stability. Because there are more sulfur compounds in the exhaust gas of diesel vehicles, the TRDN-1 molecular sieve catalyst has a good performance in sulfur poisoning resistance. Through the use of TRDN-1 molecular sieve catalyst, the emission performance of diesel vehicles has been significantly improved, and the impact on the environment and human health has been effectively controlled.

Gasoline vehicle exhaust denitrification

In addition to diesel vehicles, the TRDN-1 molecular sieve catalyst is also suitable for exhaust gas denitrification of gasoline vehicles. Although the composition of gasoline vehicle exhaust differs from that of diesel vehicles, the TRDN-1 molecular sieve catalyst can still effectively reduce the concentration of NOx in gasoline vehicle exhaust. Through the use of TRDN-1 molecular sieve catalyst, the emission performance of gasoline vehicles has also been significantly improved, contributing to environmental protection.

Industrial exhaust treatment

In addition to automobile exhaust, TRDN-1 molecular sieve catalyst is also widely used to treat various industrial exhaust. For example, the production process will produce a lot of nitrogen exhaust in the steel, chemical, ceramic and other industries. The concentration of NOx in these exhaust gases is high, which seriously impacts the environment and human health. Using TRDN-1 molecular sieve catalyst for denitration treatment, the concentration of NOx can be effectively reduced, and the environmental impact can be reduced.
