“…2. The weight loss below 140 • C was originated from the moisture retained in the reconstituted tobacco sheet, which resulted in about 4.5% weight loss [23]. The main thermal degradation took place between 140 and 530 • C. In this temperature range, there were two obvious decreases and an unobvious one in the TG curve, corresponding to the two strong peaks and a shoulder in the DTG curve, which is similar to W. Wang's research [24].…”

“…The typical DSC curve showed three main peaks during the thermal analysis of reconstituted tobacco. The fist endothermic peak between 40 and 214 • C with a maximum at approximately 107 • C is ascribed to water evaporation [23]. The exothermic degradation between 215 and 560 • C showed two exothermic peaks at about 322 and 507 • C, respectively, in the atmosphere of 10% O 2 in N 2 , which correspond to the thermal decomposition of cellulose and the combustion of the residual char, respectively [24].…”

“…Studies on the pyrolysis of tobacco have also demonstrated that the tobacco pyrolysis DTG curve can be divided into different Gaussian peaks representing the thermal decomposition of individual components [21,22]. For instance, the mass loss below 373K represents the evaporation of water [23]; The peaks between 373-473K corresponds to the thermal decomposition of sugars, nicotine, pectin and some other volatile species [24,25]; and in the temperature of 474-873K the mass loss would be attributed to the pyrolysis of hemicellulose, cellulose and lignin, respectively [26][27][28]. Moreover, Baker and Bishop have demonstrated that the thermogravimetric analysis spectra of tobacco pyrolysis is highly reproducible under well-de ned conditions [29].…”

Background: During the biomass-to-bio-oil conversion process, many researches focus on the study of the association between the biomass and the bio-products by using near infrared spectra (NIR) and chemical analysis method. However, the characterization of biomass pyrolysis behaviors by using thermogravimetric analysis (TGA) with support vector machine (SVM) algorithm has not been reported. In this study, tobacco was chosen as the object for biomass, because the cigarette smoke (including water, tar and gases) released by tobacco pyrolysis reactions decide the sensory quality, which is similar to the use of biomass as a renewable resource through the pyrolysis process. Results: Support vector machine (SVM) has been employed to automatically classify the planting area and growing position of tobacco leaves by using thermogravimetric analysis data as the information source for the first time. 88 single-grade tobacco samples belonging to 4 grades and 8 categories were split into the training, validation and blind testing set. Our model showed excellent performances in both the training and validation set as well as in the blind test, with accuracy over 91.67%. Throughout the whole dataset of 88 samples, our model not only provides precise results on the planting area of tobacco leave, but also accurately distinguishes the major grades among the upper, lower and middle positions. Error only occurs in the classification of subgrades of the middle position. Conclusions: Our results not only validated the feasibility of using thermogravimetric analysis with SVM algorithm as an objective and rapid method for automatic classification of tobacco planting area and growing position, but also showed this new analysis method would be a promising way to exploring bio-oil quality prior to biomass pyrolysis production.

“…The author concluded that the main gases and volatile products released during the combustion and pyrolysis are CO, CO 2 , NH 3 , HCN, NO, isoprene, formaldehyde, acetaldehyde, acrolein, etc. Sung and Seo (2009) studied the thermal behavior of tobacco stem on a thermogravimetric analyzer (TGA) both in air and in N 2 , and the authors reported that decomposition conditions and tobacco species had significant effect on the mass loss patterns. Li et al (2011) studied the co-combustion thermal behavior of high-ash anthracite coal, tobacco residue, and their blends on TGA under different temperatures.…”

Pyrolysis characteristics and mechanism of tobacco stem were studied by pyrolysis coupled with gas chromatography/mass spectrometry (Py-GC/MS), thermogravimetric analyzer coupled with Fourier transform infrared spectrometry, and mass spectrometry (TG-FTIR and TG-MS) techniques. The composition of evolved volatiles from fast pyrolysis of tobacco stem was determined by Py-GC/MS analysis, and the evolution patterns of the major products were investigated by TG-FTIR and TG-MS. Py-GC/MS data indicated that furfural and phenol were the major products in low temperature pyrolysis, and these were generated from depolymerization of cellulose. Indene and naphthalene were the major products in high temperature pyrolysis. TG-FTIR and TG-MS results showed that CO, CO 2 , phenols, aldehydes, and ketones were released between 167ºC and 500ºC; at temperatures >500ºC, CO and CO 2 were the main gaseous products.
