Coal Rank an overview ScienceDirect Topics
Coal rank is a measure of coal maturity and is the most fundamental parameter that relates both to the coalifiion history and the utilisation potential of a coal. Figure 14.3 shows the change in coal chemical and physical properties with rank from bituminous to anthracite coals (Teichmuller and Teichmuller, 1975).As the rank increases, the vitrinite reflectance, carbon
