Mn、Ce负载顺序对催化剂Mn-Ce/TiO2低温脱硝活性的影响
Effect of loading sequence of Mn and Ce on the activity of Mn-Ce/TiO2 catalysts at low-temperature
摘要
Abstract
Manganese and cerium oxide catalysts were prepared by sol-gel method and used for the low-temperature selective catalytic reduction (SCR) of NO with NH3. The catalysts were characterized by BET surface area,X-ray diffraction (XRD) and scanning electron microscope (SEM). The influence of loading sequence on the structure of Mn-Ce/TiO2 catalysts was investigated. The results showed that the phase structure of catalysts was anatase. Mn and Ce distributed in amorphous form. When Mn and Ce were supported on same carrier,the specific surface area of catalyst was the largest,which achieved 97.6m2/g,and active components of Mn and Ce were well distributed. The catalyst activity was also the highest when Mn and Ce were supported on same carrier. The NO removal efficiency was above 90%, when the reaction temperature was 200℃.关键词
