CoaltoLiquids. CoaltoLiquids (CTL) is a process of converting coal to fuels such as diesel or gas. For diesel, the process involves first building a plant to convert coal to gas and then another plant to covert the gas to a liquid. The resultant liquid fuel is known as synthetic fuel or synfuel. Synfuels are used as an alternative to oil ...
