Pt/Al2O3蜂窝状催化剂上NO选择性催化还原反应动力学研究

  • A honeycomb Pt/Al2O3 catalyst was prepared by multi-coating and wet-impregnation method. The catalytic performance and comparison of integral reactor and circulating reactor for selective catalytic reduction of NO over the catalyst have been studied. Based on Langmuir-Hinshelwood method and experimental results the mechanism of NO reduction by C3H6 was proposed. The mathematical expression for reaction rate of NO and C3H6 has also been established. The calculation result is consistent with the experimental data, and the result shows that the decomposition of NO on the catalyst surface is inhibited by superfluous O2 at higher temperature.
