Coal liquefaction, currently termed coal to liquids (CTL), is a chemical process for producing synthetic transportation fuels from coal to replace or supplement conventional supplies of diesel oil and gasoline derived largely from petroleum .
Coal liquefaction allows the player to turn excess coal into oil processing products.
Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using CCS would emit slightly less than the oil process but at a high cost. State owned China Energy Investment runs a coal liquefaction plant and plans to build 2 more.

fines, coal, manganese ore fines and nickel ore) that are known to be prone to liquefaction have been successfully transported without any incident. Despite an improvement in the awareness of carrying such cargoes, incidents where cargoes have been known to liquefy unfortunately continue and sometimes with catastrophic/tragic1 results.
There do exist some advantages of coal liquefaction and coal gasification, but they are overshadowed by the fact that they are more expensive than producing fuel from crude oil. Scientists are trying to come up with newer methods of using coal efficiently to produce energy, but it is bound to take some time to implement them at the ground level.

Underground coal gasification (UCG) is a method of converting unworked coal coal still in the ground into a combustible gas. UCG technology allows countries that are endowed with coal to fully utilise their resource from otherwise unrecoverable coal deposits. UCG uses a similar process to surface gasification.
Liquefaction terminals generally receive natural gas by pipeline from a well field. Before it is liquefied, the gas must be cleaned of water, carbon dioxide, hydrogen sulfide and other impurities that might freeze, become corrosive, or interfere with the liquefaction process.
