product presentation

       Within a certain exhaust temperature range, ammonia produced by the decomposition of urea aqueous solution is used as a reducing agent to reduce NOx in the exhaust gas to N2, so as to effectively reduce NOx emissions in the exhaust gas.

　　Advantages: At present, SCR catalysts for diesel engines mainly include vanadium-based SCR catalysts and zeolite-based SCR catalysts. Traditional vanad-based SCR catalyst has good sulfur resistance, low toxicity and high conversion efficiency at medium temperature. The zeolite-based SCR catalyst system has the advantages of wide temperature window, good high temperature stability, high purification efficiency, non-toxic, and its performance is obviously better than that of V2O5/WO3/TiO2 catalyst.

technical parameters

Cu-SCR：

　　NOx conversion efficiency ≥80% at 200℃;

　　Catalytic activity window ≥320℃;

　　After aging at 650℃ for 100H, the average reduction of NOx conversion efficiency at each temperature point of the catalyst is less than 5%.

　　Under WHTC, WHSC and PEMS test conditions, the catalytic performance can meet the requirements of National sixth emission regulations;
