Abstract: Selective Catalytic Reduction (SCR) technique is a main method to deal with the nitrogen oxides generated by Coal-fired power plants at present. The catalyst is the key of the whole SCR system which could be produced in many forms for different requirements, while the form of honeycomb has been widely used due to its unique structural performance and higher De-NOX efficiency. In this paper the chemical reaction principle of SCR method and types of the SCR catalyst are summarized .The industrial production process of honeycomb SCR catalyst as well as all kinds of the promoters and active components with the influences to forming and catalytic properties are emphatically demonstrated. Finally the poisoning reasons of the catalyst and the regeneration methods are described.
