cynamide process of industrial fixation


Frank–Caro process - Wikipedia

The Frank–Caro process, also called cyanamide process, is the nitrogen fixation reaction of calcium carbide with nitrogen gas in a reactor vessel at about 1,000°C. The reaction is exothermic and self-sustaining once the reaction temperature is reached.

Industrial Nitrogen Fixation - Nitrogen Cycle

Industrial Nitrogen Fixation Especially within the last century, humans have become a significant source of fixed nitrogen, producing more of it than the other sources combined. Burning fossil fuels, using synthetic nitrogen fertilizers, and cultivation of legumes are all examples of human actions that produce fix nitrogen, sending twice as much fixed nitrogen into the biosphere every year.

Nitrogen fixation in ambient conditions - EPFL

2018/12/11 · Using nitrogen as a raw material (“feedstock”) for industrial usage is accomplished by a reaction known as “nitrogen fixation”. In this reaction, molecular nitrogen (or “dinitrogen”; N 2 ) is split into two atoms of nitrogen that can then be connected to other elements like hydrogen or carbon, which allow nitrogen to be stored as ammonia or converted directly in higher value compounds.
