Bituminous coal

Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material Its primary constituents are macerals: vitrinite and liptinite The carbon content of bituminous coal is around 60–80% the rest is composed of water air hydrogen and sulfur which have not been driven off from the macerals Bank density is approximately 1346 kg/m (84 lb/ft)
