Fe/Al-PILC催化C3H6选择性还原NO的实验研究
Experimental study on selective catalytic reduction of NO with propene over iron based catalysts supported on aluminum pillared clays
摘要
Abstract
Iron based catalysts supported on aluminum pillared clays ( Fe/Al-PILC ) was prepared by impregnation method and the selective catalytic reduction of NO with propene by the Fe/Al-PILC catalysts was investigated in a fixed bed reactor. The physical and chemical properties of the catalysts were characterized by N2 adsorption/desorption, XRD, H2-TPR, Uv-vis, Py-FTIR, etc. Results showed that 9% Fe/Al-PILC reduced more than 98% of NO at 400-550 °C. SO2 and water vapor slightly influenced the catalytic activity of the catalysts. XRD and N2 adsorption/desorption characterization results revealed that the iron oxides in the catalyst were highly dispersed on the surface of the carrier, and the catalyst has a large specific surface area and pore volume. H2-TPR results indicated that the activity of the catalysts was mainly determined by the reduction performance of Fe2 O3 phase. Uv-vis results showed that the activity of the catalysts was positively correlated with the iron oxide oligomer FexOy. Py-FTIR results indicated that both Lewis acid and Br?nsted acid were formed on the catalyst surface and the Lewis acid sites were the main catalytic activity center of NO and C3 H6 reaction.关键词
