Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal type determines the composition of coal and it reflects the degree of oxidation during coalification. Based on the van Krevelen diagram (van Krevelen, 1993), coal consists of three key material groups including vitrinite, liptinite and inertinite, which are composed of distinct constituents called macerals.Table 14.2 compares the key characteristics of coal macerals (van Krevelen, 1993).
