The product I plant with the Dalian Institute of Chemical Physics, Chinese Academy of Sciences to develop. Instead of the new products of the German G-117 catalyst. Has high catalytic activity, high strength, thermal stability and good performance characteristics and resistance to poisoning and coking resistance. Mainly used for ammonia decomposition furnace, coke oven gas purification and recovery Claus furnace. Decompose toxic gases such as ammonia, hydrogen cyanide gas into N2, H2, CO2, an effective solution to the environmental pollution.
