Nitrogen oxides (NOx) are a major concern for industrial emissions. Selective Catalytic Reduction (SCR) systems are widely adopted to mitigate these pollutants, and the catalyst is the key enabler of this process. Among the various materials used, titanium dioxide (TiO2) plays a foundational role in many high-temperature SCR catalysts. At NINGBO INNO PHARMCHEM CO.,LTD., we leverage the properties of TiO2 to manufacture effective and durable SCR catalysts for a range of industrial applications.

Why TiO2 is a Preferred Catalyst Support

Titanium dioxide, particularly in its anatase and rutile crystalline forms, offers a unique combination of properties that make it an excellent support material for SCR catalysts, especially those designed for high-temperature operations:

• High Thermal Stability: TiO2 exhibits good thermal stability, allowing it to maintain its structural integrity and surface area at the elevated temperatures encountered in many industrial flue gas streams (typically 300-500°C). This is crucial for consistent performance over time. As a manufacturer, we select specific TiO2 phases to optimize this characteristic.
• High Surface Area: TiO2 can be prepared with a high specific surface area (SSA), which is vital for dispersing the active catalytic components (like vanadium or tungsten oxides) effectively. A larger SSA means more active sites are available for the reaction between NOx and ammonia (NH3), leading to higher NOx removal efficiency. We focus on producing TiO2 supports that maximize this valuable property.
• Acidity and Surface Properties: The surface acidity of TiO2 can be tuned to promote the adsorption of reactants like NH3 and NOx, facilitating the catalytic reaction. This intrinsic property of TiO2 is key to the effectiveness of SCR catalysts. We aim to optimize these surface properties when you buy our products.
• Mechanical Strength: For applications in honeycomb structures, the mechanical strength of the support material is important to prevent crushing or attrition. TiO2 generally provides sufficient mechanical robustness for these applications. Our manufacturing processes ensure the integrity of the final catalyst structure.
• Resistance to SO2 Poisoning: While sulfur dioxide (SO2) can poison some catalysts, certain formulations of TiO2-based SCR catalysts exhibit a degree of resistance, especially when properly formulated and operated. This contributes to a longer catalyst lifespan and reduced maintenance. We are a supplier committed to minimizing such deactivation pathways.
