AD-946 Ammonia Decomposition Catalyst
[ Products Description ]
AD-946 Ammonia decomposition catalyst is made from sintered MgO carried with active component of Ni and other additives. It has 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 into N2, H2 and CO3, to effectively purify the coke-oven gas for the sake of environmental protection and equipment corrosion prevention.
