Haber–bosch hb process
Webdominated by the Haber-Bosch (HB) process for over a century. Despite extensive optimization efforts, the HB process is highly energy-intensive because it requires high pressures and high recycle rates (as a result of low single-pass NH3 yield) to achieve industrially acceptable NH3 formation rates. Improving or replacing the HB WebThe Haber-Bosch (HB) process, invented by Fritz Haber and Karl Bosch in 1914, is currently responsible for the large- scale production of ammonia (NH3) fertilizer and is …
