摘要
为降低卷烟烟气中有害成分低分子醛酮化合物的含量和研究介孔材料在烟气减害中的作用及其机制,将不同微结构特征的介孔氧化铝分别添加到卷烟嘴棒中,研究其对主流烟气中八种低分子醛酮化合物含量的影响。结果显示,介孔氧化铝对低分子醛酮有明显的吸附作用,而且脱除效果与介孔氧化铝的孔径密切相关,这与介孔氧化铝的纳米限域效应有关。通过进一步研究介孔氧化铝对烟气中苯酚和苯并(a)芘的吸附作用,揭示了介孔氧化铝对低分子醛酮的选择性吸附与其因表面静电引力优先吸附极性物质的特性以及低分子醛酮的低熔沸点密切相关。烟气三项指标分析表明,介孔氧化铝对烟气中的焦油和烟碱含量影响不大,这有利于保持卷烟的香气。
To eliminate the low-molecular aldehydes and ketones in mainstream cigarette smoke and study the effect of mesoporous alumina on the adsorption of harmful components from smoke, mesoporous alumina particles with different microstructure was separately introduced into filter tip and the corresponding influences on the content of the low-molecular aldehydes and ketones in mainstream cigarette smoke were studied. The results showed that mesoporous alumina could effectively eliminate the low-molecular aldehydes and ketones from the mainstream cigarette smoke and the elimination efficiency was closely associated with the pore size of mesoporous alumina. The further study on the adsorption of phenol and benzopyrene from cigarette smoke using mesoporous alumina revealed that the preferential adsorption of low-molecular aldehydes and ketones was associated with the selective adsorption of polar molecules on mesoporous alumina and the low melting and boiling points of these aldehydes and ketones. In summary, the commendable adsorption performance of mesoporous alumina should be related to its abundant mesoporous structure, the electrostatic attraction on the interface, nanometer pore space confinement and the low melting and boiling points of low-molecular aldehydes and ketones. The analysis result about the three indicators of mainstream cigarette smoke showed that mesoporous alumina had no obvious influence on the content of Tar and nicotine in smoke.
