We can convert solid coal into synthetic natural gas by a process called coal gasification, which removes sulfur and most other impurities from coal. We can also convert it into liquid fuels such as methanol and synthetic gasoline through a process called coal liquefaction. Theses fuels, called synfuels, are often referred to as cleaner ...

FischerTropsch plants associated with biomass or coal or related solid feedstocks (sources of carbon) must first convert the solid fuel into gases. These gases include CO, H 2, and alkanes. This conversion is called gasification. Synthesis gas ("syngas") is obtained from biomass/coal gasification is a mixture of hydrogen and carbon monoxide.

direct and indirect. As the names imply, direct processes directly convert coalbased hydrocarbons into liquid fuels, while indirect processes use an intermediate process (gasification) to convert the coal into a gaseous fuel (syngas) before further refining the syngas into liquid fuels.

The process through which the solid coal is converted into liquid hydrocarbons is known as Coal liquefaction. This method is usually recognized as "Coal to X", where X may be many different hydrocarbonbased elements. This process of liquefaction takes place when saturated coal or partially saturated coal loses strength and stiffness.

Thermochemical conversion is a method of using heat to convert biomass into usable energy or fuel. Thermochemical conversion routes can be classified into combustion, gasification, liquefaction, pyrolysis, and torrefaction. Aside from combustion, all the other techniques can produce solid, liquid, and/or gaseous biofuels.
