Low-temperature oxidation of a high volatile bituminous Turkish coal was studied using an isothermal flow reactor technique under different experimental conditions. Coal samples were ground and sieved to three different particle sizes namely -850 μm, -425 μm and -300 μm. The samples were oxidised at 40, 60 and 90°C with an oxygen flow rate of 45 mL/min. CO2 and CO emissions were analysed using an HP 5897 Series II type gas chromatograph. Temperature was found to have a definite effect; as the temperature increased rates of formation of CO2 and CO also increased significantly. Experimental results showed that the rates of formation of CO2 and CO are independent of the particle size of the samples.
