coal rank and analysis in mineral processing

Coal Rank - an overview ScienceDirect Topics

2011-2-1  Coal rank is the measure of the degree of organic metamorphism (coalification) of a coal, ranging from low-rank peat to high-rank meta-anthracite (Table 3.1.5). Rank can be determined through a number of chemical and physical parameters. In general, no single parameter can be used throughout the entire rank range.

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 coalification 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 content, and C/H ...
