“…It was found that water content was between 7 and 10% in all five samples. Such water contents were observed in previous studies [25], when native and modified polysaccharides were analyzed. However, this loss of weight was greater for modified pectin samples than for native pectin.…”

“…3a and b respectively. Based on this analysis, it is possible to observe and compare the thermal behavior of the native SBP sample with the [23][24][25]. The first region (25-150 • C) is attributed to the water loss during the temperature rise.…”

“…This suggests that, as demethylation favors the unmasking of the carboxylic functions, a higher amount of hydroxyl groups may interact with the water molecules. The second region, between 150 and 350 • C corresponds to a rapid mass loss (43-47%) due to the polysaccharide decomposition, when the galacturonic acid chains start to undergo extensive thermal degradation, with the evolution of various gaseous products and the formation of solid char [24,25]. The third region (350-600 • C) shows the slow mass loss after volatilization of water and other compounds, i.e.…”

“…As shown in the results of pyrolysis at 400 o C, the yields of methanol (>14%) and acetic acid (>15%) were particularly high via the pyrolysis of mandarin peel. Compared to other biomass, mandarin peel has a considerably higher citrus pectin content, resulting in high selectivity to methanol and acetic acid [24].…”

“…It was recently reported that acetic acid was mainly formed from hemicellulose [25]; whereas, levoglucosan was from cellulose [26], phenols from lignin [27], and furfural and 1-hydroxy-propanone from holocellulose [28]. Zhou et al [24] studied the formation mechanism of the pyrolysis gases released during the pyrolysis of pectin under conditions that simulated a cigarette smoldering. They used thermogravimetric analysis, coupled to Fourier transform infrared spectrometer (TG-FTIR) and flash pyrolysis, with high performance liquid chromatography (FPy-HPLC).…”

The thermal property of the pyrolysis reaction of mandarin peel was studied using thermogravimetric analysis (TGA). Thermogravimetric analyses with temperature increases of 10, 20 and 40 o C/min showed large weight losses within the temperature range 150-590 o C. Differential thermogravimetric (DTG) analysis curves illustrated that the pyrolysis of mandarin peel was a multi-step process, consisting of water desorption, the decomposition of pectin, hemicellulose, cellulose and lignin, and devolatilization of the residual char. The apparent activation energies ranged between 119 and 406 kJ/mol, depending on the pyrolytic conversion. The pyrolysis products were analyzed, using pyrolyzergas chromatography/mass spectrometry (Py-GC/MS), to evaluate mandarin peel as a renewable source of valuable industrial chemicals. The pyrolysis products of mandarin peel contained high portions of methanol and acetic acid, as well as valuable compounds, such as limonene and vitamin E.

In this work, the pyrolysis and combustion characteristics of TLs were tested by using a nonisothermal thermogravimetric analysis, and the distribute activation energy model was used to determine the kinetic parameters. Tobacco leaves from upper, middle, and lower parts of tobacco plants were compared, and the effects of oxygen concentration and heating rate were also investigated. Results show that the decomposition and burnout performances of middle TLs were the best. When oxygen concentration is in the range of 0 to 10%, the increase of oxygen concentration brought little effect on volatile release while remarkably improving residual char burning. The mass loss curves moved backward with the increase of heating rate due to the delay of heat transfer. In general, E first increased and then decreased as mass loss, and it was also affected by oxygen concentration. Energy value under the condition of 10% oxygen concentration is much higher than that under 0% and 5% oxygen conditions. A kinetic compensation effect between E and k was investigated for small molecule species release and char oxidation in TL combustion. The general compensation effects of small molecule species release and char oxidation could be expressed as ln(k) = 0.230E − 4.73 and ln(k) = 0.215E − 17.69, respectively.
