Haber process
Catalysts

The Haber–Bosch process relies on catalysts to accelerate N hydrogenation. The catalysts are heterogeneous solids that interact with gaseous reagents.

The catalyst typically consists of finely divided iron bound to an iron oxide carrier containing promoters possibly including aluminium oxide, potassium oxide, calcium oxide, potassium hydroxide, molybdenum, and magnesium oxide.
