Study on the pyrolysis products in paper-making reconstituted tobacco substrate under different atmospheres and temperature ranges

  • Received Date: 2018-08-07
  • In order to study the effects of different atmospheres (nitrogen and air) and temperature ranges (300~500℃, 300~700℃ and 300~900℃) on the composition and amount of pyrolysis products in paper-making reconstituted tobacco substrates, solid phase microextraction, adsorption-desorption and gas chromatography-mass spectrometry methods were used for analysis. The results showed that under the nitrogen and air atmospheres, the pyrolysis products of substrates at the range of 300~700℃ and 300~900℃ obviously increased when compared with those at the range of 300~500℃. A large number of polycyclic aromatic hydrocarbons and olefins were produced in these two temperature ranges. Nicotine was only found in the pyrolysis products of substrates at the range of 300~500℃. The contents of furfural and phytadiene were higher at these three temperature ranges.In the same temperature range,under the air atmosphere,the release amount of important cleavage products such as crotonaldehyde,2-methyl-furan and furfural with relatively low molecular weight was higher than that under nitrogen atmosphere. The relative release of alcohols increased, and the presence of oxygen in air promoted the full combustion of substrates, thereby resulting in the reduction of total pyrolysis products.
