摘　　要：研究不同固体材料对烟丝热解所释放烟气的吸附性能,以及在低温加热条件下再释放烟气组分的性能,确定对烟丝热解烟气的最佳吸附方式及再释放条件,为加热不燃烧卷烟的开发提供研究基础。结果表明,Al2O3、ZSM-5和MCM-41分子筛这3种典型的固体材料对烟丝热解烟气的吸附性能与其比表面积和表面性质有关,其中Al2O3吸附烟丝热解烟气后,在加热过程中释放出的香味成分相对含量最高,而有害物质的相对含量最少,表现出最佳的性能。另外,烟丝热解气氛也影响固体材料的吸附和再释放烟气组分的性能。与含氧的热解气氛相比,N2为较佳的烟丝热解气氛,Al2O3上释放出的香味成分相对含量较高。在此基础上,通过固体材料分层吸附,可进一步显著提高加热过程中释放出的香味成分的相对含量,同时减少有害物质的相对含量。Different solid materials were applied to adsorb gas productions produced from tobacco pyrolysis at high temperature,and the gas species released from solid materials were detected when solid materials were heated at 150 ℃.As a result,the solid materials were provided for adsorption and release of pyrolyzed gas production from tobacco,to develop of smokeless tobacco products.The results show that the ability of Al2 O3,ZSM-5 and MCM-41 molecular sieve for adsorption of pyrolyzed gas productions of tobacco depends on their specific surface area and surface properties.The relative amount of aroma components released from Al2 O3 after the adsorption of pyrolyzed gas production of tobacco is higher than that released from ZSM-5 and MCM-41 molecular sieve.In contrast,the relative amount of harmful components released from Al2 O3 is lower,in contrast to molecular sieves of ZSM-5 and MCM-41.These results reveal that Al2 O3 possesses the best performance for adsorption and release of pyrolyzed gas productions from tobacco.In addition,the atmosphere during pyrolysis of tobacco influences the performance of solid material for adsorption and release of pyrolyzed gas production.Compared with the atmospheric air containing oxygen,the relative amount of aroma components released from Al2 O3 after the adsorption of gas production pyrolysized under N2 is higher.On this basis,the relative content of aroma components released from Al2 O3 during the heating process can be significantly improved by adsorbing pyrolysis gas products on layered solid materials,accompanying with the decrease in the relative amount of harmful components.
