At Ningbo Inno Pharmchem Co., Ltd., we specialize in providing advanced chemical solutions that address critical environmental challenges. Our V2O5, TiO2, Wo3 mixture honeycomb SCR catalyst is a prime example of our commitment to innovation in industrial emissions control. This article explores the scientific underpinnings of this powerful catalyst and its significant impact on reducing harmful NOx emissions.

The core function of a Selective Catalytic Reduction (SCR) catalyst lies in its ability to facilitate a chemical reaction that converts nitrogen oxides (NOx) into elemental nitrogen and water. This process is essential for controlling air pollution from industrial sources such as coal-fired power plants and cement factories. Our honeycomb SCR catalyst leverages a sophisticated blend of Vanadium Pentoxide (V2O5), Titanium Dioxide (TiO2), and Tungsten Trioxide (Wo3). This combination is meticulously chosen for its catalytic properties, promoting a high reaction rate and selectivity towards NOx conversion.

The effectiveness of our catalyst is deeply rooted in its structure and composition. The honeycomb architecture provides a large surface area within a compact volume, maximizing contact between the flue gas and the active catalytic materials. This design is crucial for achieving high NOx reduction efficiency, reported to be between 85% and 95%. The TiO2 base offers excellent thermal stability and mechanical strength, while the V2O5 acts as the primary active component for NOx reduction. Wo3 is often incorporated to enhance the catalyst's performance, particularly its resistance to sulfur poisoning, a common challenge in industrial flue gases.

Understanding the chemical reactions involved is key. In the SCR process, ammonia (NH3) is injected into the flue gas. The NH3 then reacts with NOx over the catalyst surface. The primary reactions include:

4NO + 4NH3 + O2 → 4N2 + 6H2O

2NO2 + 4NH3 + O2 → 3N2 + 6H2O

These reactions effectively neutralize the harmful NOx components, converting them into harmless gases. Our catalyst is specifically formulated to promote these reactions efficiently, while also exhibiting low SO2 conversion rates and minimal NH3 slip (unreacted ammonia escaping). This is vital for preventing secondary pollution and ensuring the overall environmental benefit of the SCR system.

The durability of our V2O5, TiO2, Wo3 mixture honeycomb SCR catalyst is another significant scientific advantage. The material is designed to withstand high operating temperatures and resist physical wear and chemical degradation, ensuring a long service life. This robust performance makes it an ideal choice for continuous industrial operations. For businesses in sectors like power generation, cement, and petrochemicals, investing in a reliable SCR catalyst is a crucial step towards sustainable operations and regulatory compliance.
