Low temperature oxidation of coals: Effects of pore structure and coal composition

Abstract The low-temperature oxidation of five coals, ranging in rank from subbituminous to anthracite, was studied in the temperature range 30–250 °C, and the reaction kinetics were elucidated. The reaction rates were independent of particle diameter 100 A, and the oxygen-containing groups which decompose to CO2 and/or CO, were playing important roles in low-temperature oxidation of coals.
