| Abstract:The chemical components of 10 kinds of reconstituted tobacco sheets （9 kinds of domestic tobacco sheets， one kind of abroad tobacco sheet） were analyzed and compared systematically for the first time in this study， and the results showed that the chemical components（hot water extract，total sugar， reducing sugar， total alkaloids， total nitrogen and ash） were different， which led to the differences of thermogravimetric characteristics and pyrolysis components. Then， the mass loss characteristics of the above reconstituted tobacco sheets in air atmosphere were analyzed and compared by thermogravimetry/differential scanning calorimetry. The results showed that the weight loss rates of different reconstituted tobacco sheets in different stages had little difference， but the temperature corresponding to the mass loss rate and maximum weight loss rate were different； in addition， the final biochar yield was significantly different （8.52%～18.09%）.Py-GC/MS was used to analyze the pyrolysis products of the reconstituted tobacco sheets and the key aroma components （3-methyl-12-cyclopentadiene， D-limonene， n-hexadecanoic acid， 2-methoxyphenol， glycerol， 2-methoxy-4-vinyl phenol and linoleic acid） and harmful components （acetone， p-cresol， acetic acid， toluene and phenol） were also analyzed and filtrated. |
