IR Spectroscopy in Rank and Group Assignment of Coal

Resumo

The possibility of express determination of the characteristics V_IR^daf, R_{o, IR}, y_IR, ΣLC_IR, and A_IR^d used in the ranking of coal on the basis of IR spectroscopy is assessed for a specific example: Kuznetsk coals of different maceral composition and metamorphic development. The IR characteristics are compared with values obtained by standard methods (V^daf, R_{o, r, y}, ΣLC, and A^d).
