Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). The syngas can be used in a variety of applications such as in the production of electricity and making chemical products, such as fertilisers.
