“…High combustibility corresponds to high fire intensity [ 38 ]. In this study, the calorific value between 16.19–18.09 kJ∙g −1 , Similar to the research results of other scholars [ 35 , 39 , 40 ], and the calorific value for LG (16.19 kJ∙g −1 ) was significantly lower than those of the other groups. The ignition points of the dead surface combustibles from the different forest types were approximately 270.0°C–290.0°C.…”

In boreal regions, the frequency of forest fires is increasing. In this study, thermogravimetric analysis was used to analyze the pyrolysis kinetics of dead surface combustibles in different forest types within the Daxing’an Mountains, China. The results show that the combustible material load of forest types, the Larix forest (LG) is relatively high. Base on the E of kinetic parameters, the LG, and Quercus forest (QM) forest types had relatively high combustibility values and comprehensive combustibility values for 1-, 10-, and 100-h time lags. According to the obtained P values, the pyrolysis of dead surface fuels with 1-, 10-, and 100-h time lags is relatively difficult in the Larix / Betula mixed forest (L-B) and QM forest types. Therefore, mixed forests of the LG, L-B, and QM tree species can be established as fire-resistant forests to establish a fire barrier, reduce the combustibility of forest stands, and reduce the possibility of forest fires.

“…RWS had a lower bulk density than SS, RWS50:SS50, and RWS75:SS25, while SS had the highest bulk density of the four samples. RWS had a lower bulk density (277.62 kg/m 3 ) than pelletised samples (652 kg/m 3 ) and extruded samples (334 kg/m 3 ), while SS had a higher bulk density than both pelletised and extruded samples [35]. Bulk density is an important parameter and plays a vital role in the physical characterisation of biomass for logistics purposes, as it affects the cost of transportation and safe storage [36].…”

Physicochemical Characterisation and the Prospects of Biofuel Production from Rubberwood Sawdust and Sewage Sludge

et al. 2021

This study aims to evaluate the physicochemical properties of rubberwood sawdust (RWS) and sewage sludge (SS) for producing biofuel or liquid products via pyrolysis and co-pyrolysis. The chemical and thermal properties of both samples were observed to have superior bioenergy production capabilities. RWS and SS had significantly different physicochemical properties, such as particle-size distribution, bulk density, ultimate and proximate analysis, lignocellulose composition, thermal-degradation behaviour, and major and minor elements. The composition of extractives was found to only marginally affect the end product. Carbon and hydrogen content, the two main elements for biofuel enhancement, were found to correlate with the organic components of both RWS (48.49, 7.15 wt.%) and SS (32.29, 4.06 wt.%). SS had a higher elemental composition of iron, calcium, and potassium than RWS. Both samples had a higher heating value of 13.98 to 21.01 MJ/kg and a lower heating value of 11.65 to 17.66 MJ/kg, a lesser energy potential than that of fossil fuels. The findings from these blends are relatively moderate due to the related lignocellulosic potential composition. The novel contribution of this research was to optimize the use of local waste materials as a new raw material for biofuel production that could serve as a sustainable fuel source.

“…The weight percentages of these components were experimentally determined according to the Van Soest procedures [25]. Extractives' content was indirectly determined by subtracting the weight percentages of hemicellulose, cellulose, lignin, and ash, from 100 wt% [26]. The higher heating value (HHV) was determined experimentally through an adiabatic bomb calorimeter IKA C200 (IKA Calorimeters, Wilmington, USA) following the ASTM D5865 standard [27].…”

“…The higher heating value (HHV) was determined experimentally through an adiabatic bomb calorimeter IKA C200 (IKA Calorimeters, Wilmington, USA) following the ASTM D5865 standard [27]. The lower heating value (LHV) was calculated from the HHV by deducting the latent heat required to vaporize water (LHV(MJ kg −1 ) = HHV(MJ kg −1 )-0.2183H(wt%)) [26]. The bulk density was determined by a graduated cylinder using ASTM E873-82 [28].…”

This study presents the first attempt to focus on the cocoa shell pyrolysis in terms of kinetic triplet, thermodynamic parameters, and evolved volatile analysis using the TGA-FTIR technique. For reliable interpretation of the multistep pyrolysis of cocoa shell, the multiple kinetic triplets were adequately estimated by a combined kinetic procedure using five independent parallel reactions with the Vyazovkin isoconversional method, the compensation effect, and the master plot method. According to the results, the multiple kinetic triplets were able to describe the pyrolysis behavior of the cocoa shell with an accuracy of R 2 > 0.9446 and the pyrolysis mechanisms exhibited different reaction models (n-order and contracting cylinder). Evolved volatile analysis suggested the presence of high-energy compounds (aromatic) and useful chemicals (aldehyde, ketone, esters, ether, and alcohols). The pre-exponential factors for the five pseudo-components of cocoa shell pyrolysis ranged from 2.56 × 10 11 to 8.66 × 10 16 min −1 (derived from the compensation effect method), while the values of E a ranged from 99 to 271 kJ mol −1 . From a comparative analysis, it was found that the results from the compensation effect method ensured the overall kinetic expression to be consistent with the experimental cocoa shell pyrolysis behavior. In contrast, the overall kinetic expression using pre-exponential factors derived from Kissinger's method failed to match the experimental curves. The pyrolytic conversion of cocoa shell into bioenergy appeared as potentially viable (E a -ΔH ≤ 5.5 kJ mol −1 ). The promising findings on the cocoa shell pyrolysis can expand the use of this residue in bioenergy applications, consisting of a great attempt toward its valorization.
