摘要

烟梗的热失重行为是研究烟梗化学特性的关键。本研究采用四种蒸汽爆炸压力梯度和三种加热速率研究了烟梗的热解特性。采用三种方法分析了热解反应动力学。结果表明,烟梗热解包括脱水、降解和碳化三个阶段。汽爆压力对烟草烟梗热稳定性的影响如下:0.5 MPa > 0.2 MPa > 0.8 MPa > 块样 > 1.1 MPa。烟梗热解遵循一阶反应动力学方程,热解实验结果与基辛格方程、唐方程、胡高张方程拟合良好。实验结果为烟草茎杆热解课题研究提供了参考。

Study on the Pyrolysis Characteristics of Tobacco Stems Under Different Steam Explosion Pressures
Thermal weight loss behavior of tobacco stems is the key to studying the chemical properties of tobacco stalks. In this research, four steam explosion pressure gradients with three heating rates were investigated for the pyrolysis characteristics of tobacco stems. Three methods were employed to analyze pyrolysis reaction kinetics. The results showed that pyrolysis of tobacco stems consists of three phases: dehydration, degradation, and carbonization. The influence of steam explosion pressure on the thermal stability of tobacco stems was as follows: 0.5 MPa > 0.2 MPa > 0.8 MPa > block sample > 1.1 MPa. The pyrolysis of tobacco stems followed the first-order reaction kinetics equation, and the pyrolysis experiments fit the Kissinger equation, Tang equation, and Hu-Gao-Zhang equation well. The experimental results provide a reference for research on the subject of pyrolysis of tobacco stems.
