Selective Catalytic Reduction (SCR) technology is indispensable for modern industrial emission control, particularly for reducing nitrogen oxides (NOx). However, the performance of an SCR system is not solely dependent on its NOx removal capability; the conversion of sulfur dioxide (SO2) to sulfur trioxide (SO3) is another critical factor. Understanding the SO2/SO3 conversion rate in SCR is essential for selecting the most effective catalysts. Ningbo Inno Pharmchem Co., Ltd. highlights the importance of this parameter in its advanced catalyst offerings.

The SO2 to SO3 conversion catalyzed by SCR catalysts can lead to significant operational challenges. Sulfuric acid mist, formed from SO3, can cause corrosion in downstream equipment, such as air preheaters and ductwork, leading to increased maintenance costs and reduced operational lifespan. Furthermore, SO3 can react with ammonia to form ammonium bisulfate, which contributes to particulate matter formation and potential plugging of heat exchange surfaces. Therefore, selecting a catalyst that minimizes this unwanted reaction is paramount for efficient industrial emission control.

Ningbo Inno Pharmchem Co., Ltd. focuses on developing and manufacturing SCR catalysts, including the widely used honeycomb ceramic SCR catalyst, with a keen eye on controlling the SO2/SO3 conversion rate. While active components like vanadium pentoxide (V2O5) are crucial for NOx reduction, they also inherently catalyze SO2 oxidation. Catalyst formulations are engineered to balance these activities. For instance, the addition of promoters like molybdenum trioxide (MoO3) has been shown to effectively suppress SO2 oxidation, especially in certain catalyst types, while tungsten trioxide (WO3) may increase it. This nuanced understanding allows Ningbo Inno Pharmchem Co., Ltd. to offer optimized solutions.

The selection of a catalyst should consider the specific operating conditions of the industrial process. Factors such as flue gas temperature, SO2 concentration, and the presence of other catalyst poisons all influence the SO2/SO3 conversion rate. For example, higher temperatures generally promote SO2 oxidation. Ningbo Inno Pharmchem Co., Ltd. provides technical support to help clients choose catalysts that are best suited for their operational parameters, ensuring both high NOx reduction efficiency and minimal SO3 generation. This makes them a valuable partner for any catalyst for power plant or other industrial applications requiring precise emission control.

By prioritizing the control of the SO2/SO3 conversion rate, Ningbo Inno Pharmchem Co., Ltd. ensures that its catalysts contribute not only to cleaner air by reducing NOx but also to the overall integrity and efficiency of industrial emission control systems. Their commitment to providing high-quality, well-formulated catalysts underscores their role in advancing sustainable industrial practices.
