Question

Carbon monoxide acts as a poison to the catalyst in Haber’s process – True or False?

• A. True
• B. False

Answer 1

The correct option is A True

Yes, carbon monoxide acts as a catalytic poison and reduces the catalytic activity of the catalyst used. Therefore, carbon monoxide has to be removed before the feed enters catalytic chamber.

In general, about 100 tonnes of catalyst is used in a reactor vessel. If the ‘poisons’ are regularly removed the the catalyst might have a life of 10 years.
