Abstract
Selective catalytic reduction SCR is a major commercial technology for NO x removal in power plants There are a lot of complex chemical reactions in SCR reactors and it is of great significance to understand the internal process of chemical reactions for SCR DeNO x and study the impact of various factors on NO x removal efficiency In this paper the impact of reaction temperature ammonianitrogen molar ratio and resident time in the catalyst bed layer on NO x removal efficiency were studied by simulation of chemical reactions Then calculated results were compared with catalyst activity test data in a power plant which proved that the simulated results were accurate As a result the reaction conditions were optimized in order to get the best removal efficiency of NO so that we can provide a reference for optimal running of SCR in power plants
