1. Product Description
This catalyst for ammonia decomposition unit is developed cooperatively by our company and chemical
physics research institute in Dalian of Chinese Academy of Sciences, for insteading of Germany G117.
It is provided with the properties of great catalytic activity, high mechanical strength, and excellent
thermal and coking resistance. It is used in the ammonia decomposing furnace to decompose the
NH3 and HCN etc. into N2, H2 and CO2, and so as to effectively purify the coke oven gas for the sake of environmental protection and prevent the equipment from corrosion.
