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.

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

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 Sasol in several different forms to produce fuels from either coal or natural gas.

The conversion of living organisms into fossil fuels is a complex process. As organisms die, most organic matter is oxidized back to CO 2 relatively quickly ... and natural gas is in a gaseous phase. Specifically, coal is a black or dark brown solid fossil fuel found as coal seams in rock layers formed from ancient swamp vegetation.

The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...

Abstract. Fuels made from coaltoliquid (CTL) have the potential to partly take the place of petroleumbased fuels. CTL is also a significant way to promote the clean and effective use of coal while resolving the imbalance between the supply and demand of petroleum oil. CTL technology is crucial from a strategic perspective for coalrich and ...
