With more heat, time, and pressure, the kerogen underwent a process called catagenesis, and transformed into hydrocarbons. Hydrocarbons are simply chemicals made up of hydrogen and carbon. Different combinations of heat and pressure can create different forms of hydrocarbons. Some other examples are coal, peat, and natural gas.

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.

There are two commercially demonstrated routes for converting coal to transportation fuels through gasification (Figure 1). The widely known Fischer Tropsch process was first discovered in the 1920s. It has been commercially practiced by in several different forms to produce fuels from either coal or natural gas.

The first stage is the conversion of coal to syngas, a mixture of carbon monoxide (CO) and hydrogen (H2). Using the socalled FischerTropsch process, these components are converted to liquid ...

Coal liquefaction is the process of converting solid coal into liquid fuel. This process has been developed as a means to utilize coal resources that are otherwise difficult to access and transport. The resulting liquid fuel, called synthetic crude oil, can be refined into a variety of fuels, including diesel, gasoline, and aviation fuel.

To do that, coal is mixed with oxygen and steam at high temperatures and pressure to produce a gas. This gas is then reacted in the presence of a catalyst to produce a synthetic oil. Already,...

Coal resources have been used to produce liquid transportation fuels by several process routes, collectively referred to as coal liquefaction or, more generally stated, as Coal to Liquids (CTL). Early records of coal conversion to liquid fuel date to 1913 and an extraction process developed by Friedrich Bergius in Germany

Another process which has recently come into prominence for the production of oil from coal is the Fischer Tropsch process. It consists of using carbon monoxide as the raw material for making the petrol. This gas is easily obtained from what is known as "water gas", a mixture of carbon monoxide and hydrogen.

Refined coal is the product of the coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and processes that alter the characteristics of coal before it is burned.

In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...
