May 13, 2020 · Why is Coal Valuable? Coal is a fossil fuel formed from dead plant matter trapped between rock deposits. Over a period of millions of years, biological and geological processes turn this material into peat and then through further metamorphosis into lignite, sub-bituminous coal and finally anthracite coal.. Coal has been used as an energy source throughout human history.

The Fischer-Tropsch 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 .
