product Description
AD-946 Ammonia Decomposition Catalyst is made
from sintered MgO carried with active component
of Ni and other additives. 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 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.The chemical reaction is as follows:
NH2→0.5N2 + 1.5H2
2HCN + 2H2O+O2→N2+5H2+2CO2 |
