The relationships between free radical concentration (N g ) and vitrinite reflectance (%R o ) of coal were tested through 36 laboratory anhydrous pyrolysis experiments. The experiments were carried out at isothermal reactor with pyrolysis temperatures ranging from 300 to 550 ยฐC over 30-480 min. The

Two bituminous coals, a high volatile Eastern Canadian and a medium volatile Western Canadian, were used to investigate the effect of oxidation on yieldsand chemical composition of gases, liquids and chars produced during coal pyrolysis. Pyrolysis experiments were performed at 500ยฐC using the Fische
