Ammonia synthesis catalyst
CATALYST OF AMMONIA SYNTHESIS
Ts 00203068-31:2015 (CN of FEA code 381 590 9000)
Catalyst of ammonia synthesis is designed for the operation under the temperature from 400 °С till 600 °С and under the pressure from 15 till 55 МРа. It is produced in two grades: SA-S (oxidize) and SA-SV (deoxidized).
The catalyst SA-SV is produced by regeneration of catalyst SA-S with hydronitric mixture.
