Analysis on the Pyrolysis Characteristic and Products of Oil-spotted Cigarette Paper Using TG-FTIR and In Situ Infrared Spectroscopy
摘要
Abstract
This study employed thermogravimetry-fourier transform infrared spectroscopy(TG-FTIR),a programmable heating platform cou-pled with a pyrolysis product collection system,and in situ fourier transform infrared spectroscopy(in situ FT-IR)combined with two-dimen-sional correlation spectroscopy(2D-COS),to investigate the effects of lubricating oil contaminants on the surface chemistry structure,pyroly-sis process,gaseous and solid pyrolysis products,and pyrolysis pathways of cigarette paper.The results showed that lubricating oil contami-nants 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 ciga-rette 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 in-creased;the comprehensive pyrolysis index decreased to 2.07×10-4%/(min·℃2),and the reaction kinetic mechanism of the pyrolysis stageⅢ changed,accompanied by a decrease in activation energy.There was increased complexity of pyrolysis products from oil-stained ciga-rette 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 sur-face altered the pyrolysis reaction pathway.关键词
