A guideline to optimizing the performance of V2O5-MoO3/TiO2 catalysts for low-temperature SCR denitrification in industrial application†
The development of novel low-temperature selective catalytic reduction(SCR)denitrification catalysts is a crucial research direction for reducing pollution and carbon emissions.Although V2O5-MoO3/TiO2 catalysts have been widely used in commercial applications,achieving effective SCR denitrification for low-temperature flue gases remains a significant challenge.In this study,the catalytic efficiency of the catalysts was systematically investigated and optimized by constructing Pearson linear correlation coefficient models between catalytic activity and different pore structures,substrate crystal planes,active site components and properties,etc.Through comprehensive characterization and experiments,anatase TiO2 loaded with 3%V2O5 and 10%MoO3 was developed and demonstrated excellent catalytic activity and stability even in high sulfur content and low-temperature environments.The catalyst was deployed in a pilot plant for over two years,consistently achieving a monthly average denitrification efficiency of over 67%and maintaining an outlet NOx concentration below 50 mg Nm-3.This study provides a robust and efficient low-temperature catalyst for SCR denitrification and offers valuable insights for future catalyst optimization.
