1. Product Description
AD-946 Ammonia Decomposition Catalyst is developed by Baisheng and Chemical Physics Research institute in Dalian of Chinese Academy of Sciences. This product can directly replace Germany G-117 catalyst with unique performance of great catalystic 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.
