Fischer-Tropsch process Simple English Wikipedia, the

Coal-based FischerTropsch factories start out with coal, gasify the coal, and then use the resulting gas as feed stock for the Fischer-Tropsch process. These factories can produce large volumes of CO 2 in this way. One of the main reasons for this approach is the large amounts of energy required for a coal-based gasification process.

How is coal formed? Kentucky Coal Education

In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite is the lowest rank of coal which means that it has the lowest heating value and lowest carbon content. Although lignite
