To produce ammonia, the hydrogen then reacts with nitrogen (derived from process air) using a magnetite catalyst under high pressure to form anhydrous liquid ammonia. This step is known as the ammonia synthesis loop (also referred to as the HaberBosch process) 3 H 2 + N 2 → 2 NH 3.

Jan 10, 2020 · The original HaberBosch process made use of osmium as the catalyst. However, osmium is not readily available. Most modern versions of the HaberBosch process use an iron catalyst instead. Iron with promoters like KOH, K 2 O, Mo, and Al 2 O 3 provide a perfectly porous and high surface area material for the reaction.

HaberBosch process or just Haber process is basically one of the most efficient and successful industrial procedures to be adopted for the production of ammonia. German chemists Fritz Haber along with his assistant in the 20th century developed highpressure devices and catalysts to carry out the process on a laboratory scale.

A brief summary of the Haber Process. The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. A flow scheme for the Haber Process looks like this Some notes on the conditions. The catalyst. The catalyst is
