Ammonia catalyst (NH3)decomposition catalyst
Ammonia decomposition catalyst
It is composed of magnesium oxide carriers processed via high-temperature calcination, and attached to the active components of nickel and other promoters. It is characterized by high catalytic activity, high mechanical strength, excellent heat resistance, and anti-coking performance. It is mainly used in the ammonia decomposition furnace of coke oven gas recovery purification to thoroughly decompose toxic gases such as NH3 and HCN into N2, H2 and CO2. This is an effective solution to the equipment corrosion and environmental pollution caused by coke oven gas.
