Such research has thus far failed to even approach the efficiency and ease of the Haber process, however.
Ammonia could be produced without overseas resources, using the Haber process.
Prior to the discovery of the Haber process, ammonia had been difficult to produce on an industrial scale.
In the Haber process for the production of ammonia, hydrogen is generated from natural gas.
Hydrogen is mainly used for the production of ammonia via Haber process.
All these methods were quickly supplanted by the less-expensive Haber process.
The Haber process uses a catalyst mostly made up of iron.
The gasses for the Haber process must be prepared before changing them into ammonia.
In the 1920s the more energy-efficient Haber process gradually took over.
The most common method is the Haber process.
