Abstract
MnOx has become a focus in the research of low-temperature SCR De-NOx catalysts for its good catalytic activity. Many MnOx-based catalysts have been researched which all have a high selectivity low-temperature N2 and good anti-poisoning, but most of them lack enough clear reaction mechanism and kinetic. In this paper, the research progress of SCR mechanisms and kinetics were summarized. The mechanisms are for the NH3 as the reducing agents and MnOx as the active centres. The overall reaction mechanism can be explained by L-H, E-R and Mars-van Krevelen mechanisms. H2O and SO2 deactivation mechanism are also mentioned. The kinetics of SCR reaction of MnOx at low-temperature are studied based on power function, mechanism derivation and the combination of them.
