| Abstract: | Objective] To study the combustion characteristics of tobacco,so as to provide scientific references for identifying the combustion performance of different types of tobacco.Method] The combustion characteristics of upper,middle and lower leaves were analyzed with Simultaneous Thermal Analysis(STA).Result] Under different gas atmosphere and temperature increase rate,the combustion index of tobacco showed as Sn(middle leaves) > Sn(lower leaves)>Sn(upper leaves),which meant that the combustion performance of middle tobacco leaves was the best.The activation energy was in the order of E(upper leaves) > E(lower leaves) > E(middle leaves) under both the nitrogen atmosphere and the mixed nitrogen-oxygen atmosphere,but the activation energy was higher in nitrogen atmosphere than in the mixed nitrogen-oxygen atmosphere.Conclusion] The established method for evaluating the combustion index and reaction kinetics can provide effective channels for identifying different types of tobacco leaves intuitively and simply. |
