The Influence of the Modified Carrier of Mn-based Low-temperature Catalyst on NH3-SCR Reaction

摘要

Introduction Nowadays selective catalytic reduction of nitrogen oxides with ammonia (NH3-SCR) in the presence of excessive O2 is considered to be a promising method, and many researchers have paid more attention on low-temperature SCR catalyst. However, the work window of the low-temperature catalyst is very limited. Therefore, it is necessary to enlarge the reaction windows of low-temperature catalyst for mobile diesel resources.
