Fig. 5. a) TG and b) DTG curves for the dust samples When the temperature reached 350 °C, the mass loss of all dust samples was about 50%, and the maximum mass loss occurred at 360 °C. However, the dust samples from P. alba and C. camphora devolatilize more than that of P. massoniana dust, and in the carbonation stage, the P. massoniana dust decomposed more than P. alba and C. camphora dust, leading to a lower content of char residue at 750 °C (Table 5). These results can be attributed to the fact that the P. massoniana dust contains turpentine and rosin, which start to decompose and carbonate at 300 °C (Wang et al. 2005).
