Question

Why iron oxide used in the ammonia production process?

(a) To reduce porous iron

(b) To increase porous iron

(c) To maximize operating temperature

(d) To maximize operating pressure

This question was posed to me by my school principal while I was bunking the class.

I would like to ask this question from Inorganic Chemical in section Inorganic Chemical Industries of Chemical Technology

Answer 1

The correct choice is (a) To reduce porous iron

Explanation: In ammonia production, preheated gas flows next through the inside of the tube which contains promoted porous iron oxide and this help to reduce porous iron in the start-up phases of operation in the synthesis reactor.
