Through the characteristic experiment, the chromatographic experiments and the thermal analysis experiments, this paper obtains that below 70°C the difference between the curve of CO and CO2 concentration of the organic sample was not significant. The production of CO and CO2 increased rapidly when the temperature rise up to more than 120°C and the maximum production rate of CO and CO2 occurs when the mineral content of organic is 5%. The oxygen consumption of different mineral content in organic samples decreases first and then increases with the increase of temperature. Among them, the maximum oxygen consumption occurs when the mineral content of organic is 5% with the increase of temperature, and the exothermic ox.
