How does the Haber process make ammonia?

ChemistryIndustry

Quick Answer

The Haber process combines nitrogen and hydrogen under high pressure and temperature in the presence of an iron catalyst. It is the main industrial method for making ammonia, first developed in the early 1900s.

The Full Story

Ammonia is produced by reacting nitrogen from air with hydrogen gas, usually over an iron-based catalyst. The reaction requires high pressure and a moderately high temperature because nitrogen is very hard to break apart. The industrial process was developed by Fritz Haber and later scaled up by Carl Bosch in the early 20th century. Today it is one of the most important chemical processes in the world because ammonia is the basis of many fertilizers.
