Experimental study on a low-temperature SCR catalyst based on MnOx/TiO2 prepared by sol-gel method
چکیده انگلیسی
A catalyst based on MnOx/TiO2 was prepared by sol-gel method for low-temperature selective catalytic reduction (SCR) of NO with NH3. Focusing on the effects of the operating parameters, the SCR reaction was investigated at temperatures from 353 to 523 K under steady and transient states. Under the optimal conditions, the efficiency of NO removal could exceed 90% at temperature of 423 K. Furthermore, within the range investigated, the reaction order of NO, NH3, O2 was determined to be 1, 0, and 0.5, respectively. Apparent activation energy was also calculated to be 38 kJ/mol, lower than that for most of the catalysts reported by previous investigations.
