What is Coal Used For?
In this process, coal is subjected to high pressure and temperature conditions in the presence of steam. As a result, a mixture of gases, called syngas is obtained. Syngas is mainly composed of carbon monoxide, hydrogen, carbon dioxide, and water vapor. The hydrogen obtained in this process can be used to make ammonia by combining it with nitrogen.
