WEBIn the 1920s the FischerTropsch process was developed to convert the main constituents of the gas, hydrogen and carbon monoxide to liquid fuels. At the beginning of the 20th century the direct liquefaction process was first done by reacting coal with hydrogen and process solvent at high temperatures and pressure to produce liquid fuels.
