High-temperature sintering method is used to prepare Z205 thermo-stable
agent.because with it small amounts of nickel as the active component
and alumina as the carrier, It can support Z204 work as the
thermo-stable agents of high temperature resistance which are applied to
top of the secondary reformer in large or medium-scale ammonia plant.
The main performance of Z205 thermo-stable agent is proper to specific
operating environment and situation on top of the secondary reformer,
and is more resistant to heat and be washed out by air current.
