High temperature cracking is the process of converting large molecules into small molecular compounds, but it requires high equipment, more energy consumption, and easily blocks pipelines. 8−10 Through hydrocracking, coal tar can obtain gasoline, diesel oil, kerosene, and other distillate fuels.

FischerTropsch process Wikipedia

FischerTropsch process Wikipedia

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.

• Indirect liquefaction begins with coal gasification: the conversion of coal to synthesis gas (a mixture of CO and H 2). • In a separate processing step, the synthesis gas is converted to liquid fuels. • Indirect liquefaction is the dominant coaltoliquids technology today. Sasol provides ≈40% of South Africa's liquid fuel

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.
