Coal or hydrogenation of coal involves raising the atomic hydrogen to carbon ratio.
Coal can be converted to liquid and gaseous fuels by direct and indirect processing.
Hydrogenation of coal is also called liquefaction of coal.
The source of coal is from various coal mines.
33.2 Hydrogenation reaction:
4(C3 H4 )n + nH2→ nC6 H6 + 5nC + nCH4
Powdered coal Aromatic liquid Hydrocarbon
This is highly exothermic reaction.
