Coal Type - an overview | ScienceDirect Topics

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).
