“…The properties of nitrogen-containing compounds extracted from tobacco wastes could maintain stable in an oxygen-lean environment. Typically, tobacco waste was one kind of biomass mainly composed of cellulose, hemicellulose, and lignin [29][30][31][32]. For the cracking of hemicellulose, the mass-loss temperature range was 210-310 • C, which matched the first mass-loss peak of tobacco wastes.…”

Alkaloids, typical nitrogen compounds, were found to be abundant in tobacco waste. The recovery of alkaloids from tobacco waste for biological pesticides could reduce the use of traditional chemical pesticides and avoid the pollution of farmland by the leaching of alkaloids from tobacco waste. Considering the fact that alkaloids can easily volatilize, thermal treatment is expected to be a potential technology to achieve the release and recovery of alkaloids from tobacco waste. For better understanding of conversion behavior of nitrogen-containing compounds in tobacco waste during thermal treatment, purge/trap-GC/MS (gas chromatography mass spectrometry), PY-GC/MS (pyrolysis-gas chromatography mass spectrometry), and fixed-bed/ATD-GC/MS (auto-thermal desorption gas chromatography mass spectrometry) were adopted to detect the ingredients and concentration of nitrogen-containing compounds in tobacco waste and/or volatiles. The results of purge/trap-GC/MS showed that nitrogen-containing compounds in tobacco waste could be effectively evaporated at 180 °C in the forms of N-benzyl-N-ethyl-P-isopropyl benzamide, 2-Amino-4-methylphenol, or N-butyl-tert-butylamine. Specifically, N-benzyl-N-ethyl-P-isopropyl benzamide was the main nitrogenous compound in the volatiles of tobacco wastes accordingly. (S)-3-(1-Methyl-2-pyrrolidinyl) pyridine was dominant in N-compounds in pyrolysis condition according to the results of Py-GC/MS. In air atmosphere, with the heating temperature increasing, the concentration of main (S)-3-(1-Methyl-2-pyrrolidinyl) pyridine was firstly increased and then decreased. Besides, the interactions between the released volatiles could be accelerated at a high temperature. Accordingly, these findings suggested that pyrolysis under proper conditions could effectively promote the extraction of alkaloids from tobacco waste.

“…These must be routinely removed to limit long term reactor degradation, ultimately resulting in intensive labour costs and an inefficient process. Specific ash components have been found to have catalytic properties which can drive various beneficial thermochemical reactions and promote for example syngas production during gasification [17][18][19]. However, a major concern with ash components such as K, Na, Ca, Mg, Cl and S are their reactivity with reactor bed media, especially when using fluidised bed technologies [7,20].…”
