For chemical engineers and procurement specialists in the environmental protection sector, a deep understanding of Selective Catalytic Reduction (SCR) catalyst performance is crucial for making informed purchasing decisions. As a manufacturer committed to delivering high-quality solutions, we aim to clarify the essential performance indicators and what they mean for your industrial operations.

The primary function of an SCR catalyst is to facilitate the reduction of nitrogen oxides (NOx) in flue gases. High activity and removal efficiency are therefore paramount. This refers to the catalyst's ability to effectively convert NOx into nitrogen and water vapor at the operating temperature. When comparing products from different suppliers, look for catalysts that consistently achieve high conversion rates, often exceeding 90%, even under challenging conditions.

Another critical performance metric is the SO2 conversion rate. Sulfur dioxide (SO2) present in flue gases can react with ammonia to form ammonium bisulfate, which can lead to catalyst deactivation and plugging. A low SO2 conversion rate, ideally below 1%, is a strong indicator of a well-designed catalyst that minimizes these undesirable side reactions. This feature is a significant advantage offered by our SCR catalysts, ensuring greater longevity and efficiency for your system.

Resistance to poisoning and abrasion is vital for the long-term viability of any catalyst. Industrial flue gases often contain various contaminants that can poison the active sites of the catalyst, reducing its effectiveness. Similarly, particulate matter in the gas stream can cause physical abrasion. Catalysts engineered with robust materials and specific surface treatments demonstrate superior resistance to these detrimental effects, ensuring sustained performance. We pride ourselves on offering catalysts with excellent abrasion resistance, a key factor for mechanical service life up to 50,000 hours.

When you plan to buy SCR catalysts, consider the overall durability and stability, often reflected in the catalyst's ability to maintain its performance over an extended period. A typical service life of 24,000 hours is a benchmark for quality. By scrutinizing these performance indicators and choosing a reputable manufacturer and supplier, businesses can ensure they are acquiring a catalyst that delivers maximum environmental benefit and operational reliability.
