Haber Process Magnetite Catalyst Damage (1 Viewer)

[serge]

Hey everyone

Every textbook I read pretty much says
that the temperature and pressure of the Haber Process
need to be monitored by a chemist for a bunch of reasons

one of them being possible damage to the
iron-oxide (magnetite) catalyst...

So what is it that can damage magnetite
extremely high temps or pressures?

thanks in advance people

Im not entirely sure but i think reasons are that impurities in the system (such as CO2) react with the catalyst spoiling it

Sulphur, CO.

thanks, CC said CO will "poison" the catalyst
by sticking to it, and that excessive heat can
damage magnetite, my chem-nerd
sister suggesting high temps will change
the molecular structure of the catalyst
