an event of fast mass loss occurring in the range of 230–360 °C ( Fig. 4A ), as well as further slow mass loss in the range of 360–600 °C, which is usually attributed to the elimination of carbonaceous material. In general, the degradation of casein

) suggesting that the carbonaceous material is oxidised in air, but is stable in this temperature range in an argon atmosphere. This observation is consistent with a charcoal rather than organic matter such as oils or polymer resin materials. Step II shows a

used thermal analysis techniques to study the thermal chemical behavior of carbonaceous materials. There are two modes of TG for estimating the reactivity of coal: isothermal [ 10 – 15 ] and non-isothermal [ 16 – 21 ]. In this work, the Hailar lignite
