“…Therefore, the charcoal with the highest ignition index is easier to ignite (QIAN et al, 2012). Xiong et al (2014) also observed an increase in the ignition temperature and the burnout temperature and a decrease in the combustion characteristic rate with increasing fi nal temperature of carbonization for sawn bamboo, corroborating the fi ndings of this study.…”

“…The first peak can be attributed to the combustion of cellulose and hemicelluloses by means of the formation and emission of volatile (TSUJIYAMA; MIYAMORI, 2000). The transition from the combustion of the residual cellulose and lignin occurs, resulting in a The characteristic combustion index (S) refl ects the reactivity of the combustion of the charcoal throughout the oxidation reaction and the higher this ratio the better the performance of the fuel during of the combustion (QIAN et al, 2012;XIONG et al, 2014). Therefore, the charcoal with the highest ignition index is easier to ignite (QIAN et al, 2012).…”

ABSTRACT:In recent years, studies have examined the use of lignocellulosic wastes for energy generation. However, there is a lack of information on the combustibility of the residual biomass, especially the bark and charcoal of babassu nut. In this study, thermogravimetric analysis (TGA), differential thermal analysis (DTA) and differential scanning calorimetry (DSC) were used to achieve the following objectives: to evaluate the combustion of the residual biomass from the babassu nut; to evaluate the combustion of charcoal produced from this biomass, considering different final carbonization temperatures; and to determine the effect of the final carbonization temperature on the thermal stability of charcoal and on its performance in combustion. Thermal analyses were performed in synthetic air. In order to evaluate the characteristics of charcoal combustion and fresh biomass, the ignition temperature (T i ), the burnout temperature (T f ), characteristic combustion index (S), ignition index (D i ), time corresponding to the maximum combustion rate (t p ), and ignition time (t ig ) were considered. The combustion of the babassu nutshell occurred in three phases and it was observed that this lignocellulosic material is suitable for the direct generation of heat. The increase in the final carbonization temperature caused an increase in the ignition temperature, as well as in the burnout temperature, the ignition time and the time corresponding to the maximum combustion rate. The results indicate that the increase in the carbonization temperature causes a decrease in combustion reactivity and, consequently, the charcoals produced at lower temperatures are easier to ignite and exhibit better performance in ignition.COMBUSTÃO DA BIOMASSA E DO CARVÃO VEGETAL DA CASCA DO COCO BABAÇU RESUMO: Nos últimos anos, pesquisadores têm analisado o uso de resíduos lignocelulósicos para geração de energia. No entanto, há uma falta de informação sobre a combustibilidade da biomassa residual, especialmente a casca e o carvão vegetal do coco babaçu. Neste estudo foram utilizadas as análises termogravimétricas (TGA), térmica diferencial (DTA) e de calorimetria exploratória diferencial (DSC) para: avaliar a combustão da biomassa residual do coco babaçu; avaliar a combustão do carvão vegetal produzido a partir dessa biomassa, considerando diferentes temperaturas finais de carbonização; e verificar o efeito da temperatura final de carbonização na estabilidade térmica do carvão vegetal e no seu desempenho na combustão. As análises térmicas foram realizadas em atmosfera de ar sintético. Para avaliar as características da combustão do carvão vegetal e da biomassa in natura foi considerada a temperatura de ignição (Ti), a temperatura final da combustão (Tf), o índice característico da combustão (S), o índice de ignição (Di), o tempo correspondente à máxima taxa de combustão (tp) e o tempo de ignição (tig). A combustão da casca do coco babaçu ocorreu em três fases distintas e observou-se que esse material lignocelulósico apresenta aptidão para ...

“…Yields are known to vary due to the differences in the relative abundance of cellulose, hemicellulose and lignin within different biomass, which have different thermal degradation kinetics [13]. Xiong et al [27] also observed biochar yields decreased at higher carbonization temperatures. The differences between the resultant biochars were most likely attributable to the thermal resilience of lignin, as opposed to hemicellulose and cellulose that decompose at temperatures lower than 400 • C (220 to 315 • C and 315 to 400 • C, respectively).…”

Thermal Properties of Biochars Derived from Waste Biomass Generated by Agricultural and Forestry Sectors

Waste residues produced by agricultural and forestry industries can generate energy and are regarded as a promising source of sustainable fuels. Pyrolysis, where waste biomass is heated under low-oxygen conditions, has recently attracted attention as a means to add value to these residues. The material is carbonized and yields a solid product known as biochar. In this study, eight types of biomass were evaluated for their suitability as raw material to produce biochar. Material was pyrolyzed at either 350 • C or 500 • C and changes in ash content, volatile solids, fixed carbon, higher heating value (HHV) and yield were assessed. For pyrolysis at 350 • C, significant correlations (p < 0.01) between the biochars' ash and fixed carbon content and their HHVs were observed. Masson pine wood and Chinese fir wood biochars pyrolyzed at 350 • C and the bamboo sawdust biochar pyrolyzed at 500 • C were suitable for direct use in fuel applications, as reflected by their higher HHVs, higher energy density, greater fixed carbon and lower ash contents. Rice straw was a poor substrate as the resultant biochar contained less than 60% fixed carbon and a relatively low HHV. Of the suitable residues, carbonization via pyrolysis is a promising technology to add value to pecan shells and Miscanthus.

“…Most of the species richness is found in Pacific Asia and South America (Bystriakova et al 2003;Das et al 2008). Bamboos are used for a wide range of applications such as for umbrella handles, fishing rods, mud huts, mats, baskets (Bystriakova et al 2003), concrete reinforcement (Ghavami 2005), building material for supporting structures (Van der Lugt et al 2006), charcoal preparation (Xiong et al 2014;Xia et al 2016), cellulose extraction (Li et al 2015), hybrid microfibers fabrication (Yu et al 2014), and forages for maintaining environmental conditions (Panizzo et al 2016). Due to their fast growth rate (5-7 years to mature) and some potential fuel characteristics, e.g., low ash content, alkali index or heating value, they might also be a valuable resource for energy (Bystriakova et al 2003).…”
