How coal is formed step by step? | AnswersDrive

Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster.

Coal Reserves. In the peat swamp as dead plant matter accumulates, aerobic bacteria rapidly oxidize cellulose and other components producing methane (CH 4), carbon dioxide and ammonia (from the nitrogen containing components).The resulting decomposed material compacts about 50% and is largely composed of lignin, a complex, 3-dimensional polymer rich in benzene rings.
