The coal gasification process is currently developed as one of clean coal technologies. Gasification is a high-temperature process (above 800 °C) in which the coal reacts with a gasifying agent, e.g. air, oxygen, or water vapor. As a result, under conditions of elevated temperature and pressure, chemical bonds in the molecular structure of coal break up and the mixture of water vapor, oxygen, carbon monoxide, and hydrogen, commonly known as syngas, is produced. The chemical composition of the obtained syngas is de...
