摘要

Abstract

A series of different transition metals (V

Cu and Zn) promoted H-ZSM-5 catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD)

scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic activity of these catalysts was evaluated for the selective catalytic reduction (SCR) of NO with NH

as reductant in the presence of oxygen. The results revealed that the catalytic activity of Cu-ZSM-5 nanocatalyst for NO conversion to N

was 80% at 300 ℃

which was the best among various promoted metals. Design of experiments (DOEs) with Taguchi method was employed to optimize NH

-SCR process parameters such as NH

/NO ratio

concentration

and gas hourly space velocity (GHSV) over Cu-ZSM-5 nanocatalyst at 250 and 300 ℃. Results showed that the most important parameter in NH

-SCR of NO is O

concentration; followed by NH

/NO ratio and GHSV has little importance. The NO conversion to N

of 63.1% and 94.86%was observed at 250 ℃ and 300 ℃

respectively under the obtained optimum conditions.
