AD-946 Ammonia Decomposition Catalyst
AD-946 Ammonia Decomposition Catalyst is cooperatively developed by our company and chemical physics research institute in Dalian of Chinese Academy of Sciences, for insteading of Germany G-117. 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.

Secondary Reforming Catalyst
Secondary reforming catalyst is kind of Precipitation type reforming catalyst taking nickel as active component and alumina as carrier, which is mainly used for secondary steam reforming process using methane gas as raw material such as natural gas, oil field gas, coke-oven gas, refinery gas.
Secondary reformer works with high temperature, LHZ02Y catalyst need to resistant to higher temperature than primary reforming catalyst. Use along with LHZ03Y guard catalyst would make them work well with excellent crush strength and resistance to 1300℃.

Methanation Catalyst
LHMC01 methanation catalyst is of Titanium rare earth nickel catalyst which is suitable for synthesis ammonia unit or hydrogen plant, to remove CO and CO2 at low concentration and make them to be inert gas, methane and water.
This catalyst has high crush strength, large pore volume, high activity and easily to be unloading. It has been obviously performing much better than other similar catalyst under high pressure and high space velocity.
