“…The pollutant emissions from tobacco burning were seriously harmful for human and public health . The previous works have shown that the pollutant emissions were affected by the pyrolysis or combustion conditions, such as temperature, oxygen concentration, heating rate, gas flow rate, and mineral matter; thus, it is important to study the process of tobacco burning. However, it is difficult to experimentally obtain the detailed information on the practical and dynamical burning processes of tobacco materials due to the complexity of unsteady cigarette burning process and the limitation of measurement methods .…”

In this work, the pyrolysis and combustion characteristics of TLs were tested by using a nonisothermal thermogravimetric analysis, and the distribute activation energy model was used to determine the kinetic parameters. Tobacco leaves from upper, middle, and lower parts of tobacco plants were compared, and the effects of oxygen concentration and heating rate were also investigated. Results show that the decomposition and burnout performances of middle TLs were the best. When oxygen concentration is in the range of 0 to 10%, the increase of oxygen concentration brought little effect on volatile release while remarkably improving residual char burning. The mass loss curves moved backward with the increase of heating rate due to the delay of heat transfer. In general, E first increased and then decreased as mass loss, and it was also affected by oxygen concentration. Energy value under the condition of 10% oxygen concentration is much higher than that under 0% and 5% oxygen conditions. A kinetic compensation effect between E and k was investigated for small molecule species release and char oxidation in TL combustion. The general compensation effects of small molecule species release and char oxidation could be expressed as ln(k) = 0.230E − 4.73 and ln(k) = 0.215E − 17.69, respectively.
