In order to develop a catalyst for low temperature selective reduction of NO in coal combustion flue gas in presence of ammonia, metallic salt impregnated metal oxides were studied in a continuous quarts fixed-bed reaction system. It was observed that the DeNOx activity of metal chloride impregnated catalyst is higher than the sulfate of the same metal at 100℃. Its activity is influenced by reaction temperature, ammonia gas, and the kind of support. The chloride ion on the metal chloride supported catalyst seems to contribute to its activity.
