| 摘要:本研究通过热重红外联用仪（TG-FTIR）、程序控温加热平台耦连热解产物捕集分析，以及原位傅里叶变换红外光谱仪（in situ FT-IR）结合二维相关红外光谱（2D-COS）分析等手段，探究了润滑油污染物对卷烟纸表面化学结构、热解过程、热解气固相产物特征及热解路径的影响。结果表明，润滑油污染物可浸染卷烟纸表面纤维，表面官能团呈现明显的长碳链烷烃类物质吸收峰，润滑油组分与卷烟纸填料间存在相互作用。油斑卷烟纸的纤维素分解阶段（热解阶段Ⅱ）最大质量损失速率降至12.12 %/min，热解阶段Ⅱ的最大质量损失速率温度、炭化成焦阶段（热解阶段Ⅲ）的质量损失率及终止热解温度均升高，且综合热解指数降至2.07×10-4 %/( min·℃²)，热解阶段Ⅲ的反应动力学机理改变且活化能降低。油斑卷烟纸热解产物的复杂度增加，高温热解条件下的烃类、酯类等热解产物相对含量升高，稠环芳烃类物质检出，2D-COS分析表明，表面润滑油污染改变了卷烟纸热解反应路径。 |
| Abstract:This study employed thermogravimetry-fourier transform infrared spectroscopy (TG-FTIR), a programmable heating platform coupled with a pyrolysis product collection system, and in situ fourier transform infrared spectroscopy (in situ FT-IR) combined with two-dimensional correlation spectroscopy (2D-COS), to investigate the effects of lubricating oil contaminants on the surface chemistry structure, pyrolysis process, gaseous and solid pyrolysis products, and pyrolysis pathways of cigarette paper. The results showed that lubricating oil contaminants infiltrated the fiber on the surface of cigarette paper, and the surface functional groups exhibited distinct long-chain alkane substances absorption peaks, indicating interactions between the lubricating oil components and the fillers in the cigarette paper. For oil-stained cigarette paper, the maximum mass loss rate during the cellulose decomposition stage (pyrolysis stage Ⅱ) decreased to 12.12 %/min; the peak temperature of pyrolysis stage Ⅱ， the mass loss percentage and the final pyrolysis temperature of charring stage (pyrolysis stage Ⅲ） all increased; the comprehensive pyrolysis index decreased to 2.07×10-4 %/(min·℃2), and the reaction kinetic mechanism of the pyrolysis stage Ⅲ changed, accompanied by a decrease in activation energy. There was increased complexity of pyrolysis products from oil-stained cigarette paper. Under high-temperature pyrolysis conditions, the relative contents of hydrocarbons, esters, and other species increased, and polycyclic aromatic hydrocarbons were detected. The 2D-COS analysis showed that lubricating oil contamination on the cigarette paper surface altered the pyrolysis reaction pathway. |
