Study of M-ZSM-5 nanocatalysts (M: Cu, Mn, Fe, Co …) for selective catalytic reduction of NO with NH3: Process optimization by Taguchi method
摘要
Abstract
A series of different transition metals (V
Co
Cr
Mn
Fe
Ni
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
3
as reductant in the presence of oxygen. The results revealed that the catalytic activity of Cu-ZSM-5 nanocatalyst for NO conversion to N
2
was 80% at 300 ℃
which was the best among various promoted metals. Design of experiments (DOEs) with Taguchi method was employed to optimize NH
3
-SCR process parameters such as NH
3
/NO ratio
O
2
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
3
-SCR of NO is O
2
concentration; followed by NH
3
/NO ratio and GHSV has little importance. The NO conversion to N
2
of 63.1% and 94.86%was observed at 250 ℃ and 300 ℃
respectively under the obtained optimum conditions.
