For this reason, any process used to convert coal to alternative fuels must add hydrogen (either directly or in the form of water). Gasification refers to the conversion of coal to a mixture of gases, including carbon monoxide, hydrogen, methane, and other hydrocarbons, depending on the conditions involved. Gasification may be accomplished either in situ or in processing plants.

Is burning coal a chemical change? Why or why not? - Quora

A combustion is the chemical reaction (redox reaction) of coal with oxygen O2. It is exothermic, which means it releases energy : hence the heat. Burning coal is in fact not one type of combustion, but several types of combustion in competition producing CO2 and water, and other compounds such as small hydrocarbons and carbon monoxide.
