摘要 实现工业烟气的超低排放及多污染物协同控制是当前大气污染治理的重要任务。本工作以负载型Mn基尖晶石催化剂为研究对象,通过Co、Ce金属改性的方式研发了一种低温选择性催化还原(Selective catalytic reduction,SCR)脱硝兼顾CO氧化的CoMn2O4/Ce-TiO2双功能催化剂。研究了不同烟气组分对同时脱硝脱CO效率的影响:SO2对脱硝效率、脱CO效率均表现出抑制作用,而H2O降低了NOx转化率却可以提高CO转化率;CO与NH3在较低浓度下起到双还原剂的作用,共同提升NOx转化率,而在较高浓度时,二者由于竞争吸附导致CO转化率下降。分析认为,Mn是主要的SCR反应活性位点,Co是主要的脱CO活性位点,而Ce物种对SCR反应和脱CO反应都具有一定的作用。在同时脱硝脱CO反应中,NOx主要通过NH3-SCR反应脱除,CO主要通过氧化反应脱除。

Abstract: Achieving ultra-low industrial flue gas emissions and synergistically controlling multiple pollutants are key tasks in air pollution management today. In this work, a loaded Mn-based spinel catalyst was used as a research object, and a bifunctional CoMn2O4/Ce-TiO2catalyst for low-temperature SCR denitrification and CO oxidation was developed through modification of Co and Ce. The impacts of different flue gas components on the efficiency of simultaneous denitrification and de-CO (decontamination of CO) were mainly investigated:SO2 inhibited denitrification and de-CO efficiency, whereas H2O lowered NOx conversion rate but enhanced CO conversion rate; CO and NH3 acted as a double reductant at lower concentrations, which jointly promoted the improvement of the NOx conversion rate, whereas the two caused a decrease of the CO conversion rate due to the competition for adsorption at higher concentrations. The analysis reveals that Mn was the primary active site in the SCR reaction, Co was the primary active site in the de-CO reaction, and Ce species played a role in both the SCR and de-CO reactions.The simultaneous denitrification and de-CO process eliminated NOx through the NH3-SCR reaction and CO through the oxidation reaction.
