“…Their yields decreased with increasing torrefaction temperature, implying that increasing torrefaction severity could abate the oxygen content and improve bio-oil quality (Wigley et al, 2016). The decrease in phenols under higher torrefaction temperatures was in line with the result of Gogoi et al (2017) where they pointed out that an increase in torrefaction temperature and time might decrease the yield of phenols, resulting from lignin decomposition and carbonization during the torrefaction process. As for the cellulose in the RWS, the influence of torrefaction at 250 °C upon cellulose was more than that at 200 °C.…”

The aim of this study was to investigate the effect of torrefaction on the pyrolysis of rubber wood sawdust (RWS) using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). Three typical torrefaction temperatures (200, 250, and 300 °C) and pyrolysis temperatures (450, 500, and 550 °C) were considered. The results suggested that only diethyl phthalate, belonging to esters, was detected at the torrefaction temperatures of 200 and 250 °C, revealing hemicellulose degradation. With the torrefaction temperature of 300 °C, esters, aldehydes, and phenols were detected, suggesting the predominant decomposition of hemicellulose and lignin. The double-shot pyrolysis indicated that the contents of oxy-compounds such as acids and aldehydes in pyrolysis bio-oil decreased with rising torrefaction temperature, implying that increasing torrefaction severity abated oxygen content in the bio-oil. With the torrefaction temperature of 300 °C, relatively more cellulose was retained in the biomass because the carbohydrate content in the pyrolysis bio-oil increased significantly.

Recently, incentives have been provided in many countries, including Canada and Denmark, to produce biochar for construction usage. This is done because biochar is carbon negative and can help achieve the emission reduction goal of 2030. This technical note aims to analyze the efficiency of biochar in soils with varying grain size distribution for enhancing water retention capacity (WRC). The combinations of biochar content and grain size distributions corresponding to the maximum and minimum efficiency were explored. Artificial Neural Network (ANN) based model for predicting Soil Water Characteristic Curve (SWCC) as a function of soil suction and grain size distribution was developed. A new factor (the ratio of fine (silt + clay) and coarse (sand) content) was proposed for the interpretation of the efficiency of biochar in soils. The newly developed model is able to predict SWCC reasonably well. Biochar amendment is found to influence both dry and wet sides of soils with a clay content lower than threshold content (6–8%). Beyond threshold content, the influence of biochar appears to reduce. However, in the case of high sand content soils (90%), the NWC value on the drier side is generally higher as compared to soils with lower sand content. Based on sensitivity analysis, it was found that the ratio of fine to sand content is the most influential, while biochar content is the least influential.

“…The pyrolysis of torrefied biomass produces less bio-oil and tar and more biochar when increasing torrefaction temperatures are used (Wannapeera et al, 2011;Ren et al, 2013;Ren et al, 2014;Doddapaneni et al, 2016). On the one hand, Gogoi et al (2017) revealed that biochar from torrefied biomass showed improved adsorption performance compared to that of non-torrefied biomass. On the other hand, Chen et al (2017) reported a decreased specific surface area.…”
