以活性炭为载体的负载型催化剂的SCR脱硝性能
Performance of SCR denitration of impregnated catalysts using activated carbon as support
摘要
Abstract
The new impregnated catalyst with low temperature,low cost and high efficiency was prepared for SCR denitration by choosing activated carbon as support and impregnating Fe,Cr,Cu,Mn and other transition metal components with impregnation method.The influence of different parameters,such as active components,impregnated quantity,reaction temperature,oxygen concentration,superficial velocity and so on,on the efficiency of SCR of NOx were studied experimentally.The results show that the activity of Mn is superior to those of Cu,Cr and Fe,and is better to promote the catalytic removal of NOx.The NOx removal efficiency of multi-component catalyst is higher than that of single-component one.When the activated carbon are impregnated with 8 ％ Mn,Cu,Cr and Fe,the NOx removal efficiency of the catalyst reaches the highest level.The NOx removal efficiency under certain oxygen content is higher than that under oxygen-free condition.And the catalyst 8Mn-8Fe/AC has the most stable performance and the highest NOx removal efficiency in all impregnated catalysts prepared by this paper.关键词
