Types of NOx Reduction Catalysts

Honeycomb Catalyst

The honeycomb NOx reduction catalyst is a technology used to remove nitrogen oxides (NOx) from fuels like coal and oil, helping to reduce NOx emissions into the atmosphere.

Key Benefits of Honeycomb NOx Reduction Catalysts:

• Efficient NOx Reduction: Honeycomb catalysts effectively decompose nitrogen oxides generated during combustion, particularly nitrogen monoxide (NO) and nitrogen dioxide (NO₂). This helps reduce harmful NOx emissions, thereby improving air quality.
• Wide Industrial Applications: Honeycomb catalysts can be applied in various industrial sectors, including power plants, steel mills, and cement factories, where significant NOx emissions are common. This technology is crucial for helping industries comply with environmental regulations and reducing their environmental impact.
• Low-Temperature Efficiency: Honeycomb catalysts can achieve high efficiency in NOx removal at relatively low temperatures, which is advantageous since traditional NOx reduction technologies may require higher temperatures for similar effectiveness.
• Energy and Cost Savings: By reducing NOx emissions during the energy production process, honeycomb catalysts contribute to increased energy efficiency and reduced fuel consumption, thereby achieving energy conservation and emission reduction goals.
• Compliance with Environmental Standards: Using honeycomb NOx reduction catalysts helps industrial enterprises meet or exceed environmental regulatory standards, reducing adverse environmental impacts and supporting sustainable development.

NOx Reduction Catalyst Module

The NOx reduction catalyst module is a device used to reduce nitrogen oxide (NOx) emissions, widely applied in industrial emission control and vehicle exhaust systems. Its main function is to chemically convert harmful nitrogen oxides into nitrogen (N₂) and water (H₂O), thereby reducing NOx emissions and protecting the environment.

1. Working Principle The NOx reduction catalyst module typically contains one or more catalyst materials, such as titanium oxides, platinum, or palladium. When exhaust gases pass through the catalyst module, the catalyst materials facilitate chemical reactions between nitrogen oxides and a reducing agent (such as ammonia (NH₃) or urea). These reactions convert nitrogen oxides into nitrogen and water, effectively reducing emissions. Common NOx reduction technologies include Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR).
2. Key Features
   • High NOx Reduction Efficiency: The catalyst module effectively converts nitrogen oxides into harmless nitrogen and water, achieving significant emission reductions.
   • Broad Applicability: Suitable for various exhaust systems, including industrial boilers, gas turbines, and vehicle exhaust systems.
   • Long Service Life: High-quality catalyst materials have a long service life, maintaining stable performance over extended periods.
   • High-Temperature Resistance: Designed to withstand high-temperature conditions, ensuring effective operation in high-temperature environments.
3. Advantages
   • Reduced Environmental Pollution: By converting nitrogen oxides into harmless substances, the catalyst module effectively reduces air pollutants, protecting the environment and public health.
   • Improved Emission Compliance: Helps meet government regulations and standards for nitrogen oxide emissions.
   • Enhanced Equipment Performance: Effective NOx control improves the performance and reliability of emission control equipment.
4. Applications
   • Industrial Boilers: Used in the exhaust systems of industrial boilers to reduce NOx emissions and meet environmental requirements.
   • Gas Turbines: Applied in gas turbine exhaust systems to lower NOx emissions, protecting equipment and the environment.
   • Vehicle Exhaust Systems: Installed in vehicle exhaust systems to reduce NOx emissions during operation.
   • Power Plants: Used in emission control systems of power plants to reduce NOx emissions during electricity production.
