Abstract
Low temperature oxidation could change the structure and properties of bitumite. Experimental results showed that the calorific value of coal decreased and the structure changed after low-temperature oxidation. Vitrinite and inertinite have almost the same radical groups. Radical groups‘ content in vitrinite was significantly higher than that in inertinite. Hydrogen peroxide oxidation altered less the thermodynamic property of the bituminite. Thermogravimetric graph slightly moved to low temperature zone after hydrogen peroxide oxidation and thermal enthalpy decreased.
