liquids. Because the coal is first gasified before conversion to liquid fuels, the FischerTropsch (FT) process for CTL is known as a type of indirect coal liquefaction (ICL). ICL is a completely different approach from DCL for providing liquid fuels from coal. ICL processes first convert coal to a gaseous intermediate, which is then ...

• 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

Conversion: Gas oil into petrol. Catalytic cracking is aided by adding hydrogen gas during the hydrocracking process. The CC bonds are broken down using it. The major products from this process are diesels, jet fuel, and LPG. It is based on the fusion of two distinct processes known as catalytic cracking and hydrogenation.

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.

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.

Liquefaction is the thermochemical conversion of an organic solid into a liquid composed of heavy molecular compounds with characteristics similar to petroleumbased liquids such as fuel oils. Liquefaction may also involve the production of a liquid from a pyrolytic gas stream. The materials treated by pyrolysis include:

Gasification Introduction |

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...
