Pyrolysis of fast growing wood Macaranga gigantea: Product characterisation and kinetic study

Valorization of Wood Residues from Vegetation Suppression during Wind Energy Plant Implementation and Its Potential for Renewable Phenolic Compounds through Flash Pyrolysis: A Case Study in Northeast Brazil’s Semi-Arid Region

“…The hemicellulose mass content in CP wood residue aligns closely with the range observed in hardwood biomasses (16.8-18.7 wt.%) [37]. Typical volatile reaction products from the thermal decomposition of cellulose and hemicellulose include short-chain oxygenated compounds, acetic acid, furan derivatives, ketones, and a small content of hydrocarbons [38][39][40]. Lignin contents ranged from 19.1 to 30.6 wt.%, with the highest observed in CL wood residue.…”

“…The volatile reaction products, including short-chain oxygenated compounds (C 1 -C 4 ), acetic acid, furan derivatives, cyclic ketones, other oxygenated cyclic compounds, and alkanes, observed from the three wood residues during flash pyrolysis, can be attributed to the thermal decomposition of cellulose and hemicellulose. Literature investigations yielded evidence that supports this hypothesis [38][39][40]. As illustrated in Figure 2, the class of short-chain oxygenated compounds (C 1 -C 4 ) constituted the second-largest proportion of the volatile reaction products, exhibiting the following order: CP (20.98%) > CL (20.59%) > AP (18.19%).…”

“…A unique hydrocarbon, 2,7-dimethyl-octane, was identified in the volatile pyrolysis products of wood residues from all three suppressed species, with its highest relative concentration (3.0%) observed in the AP wood residue. The occurrence of 1,2,4-trimethoxybenzene, an oxygenated cyclic compound, in the volatile pyrolysis products derived from CP and CL wood residues, exhibits its maximum relative concentration (2.4%) in the CP wood residue and is commonly ascribed to the thermal decomposition of lignin [39].…”

“…In contrast, phenol and 4methylphenol emerged as the sole products among the H-type phenolic compounds, while 2,6-dimethoxyphenol stood out as the exclusive product among the S-type phenolic compounds. The formation of S-type phenolic compounds (containing two -OCH3) is attributed to the cleavage of syringyl groups within the lignin macromolecule [39]. The prevalence of G-type phenolic compounds (methoxy groups indicates) indicates the predominance of the guaiacyl unit in the alkali lignin.…”

The use of wood waste from construction and demolition to produce sustainable bioenergy—a bibliometric review of the literature

“…Among the most cited papers can be found papers addressing subjects like characteristics of hemicellulose, cellulose, and lignin pyrolysis, 30 fast pyrolysis of biomass, 31 combustion properties of biomass, 32 or biomass resource facilities, and biomass conversion processing for fuels and chemicals. 33 The latest published articles are dealing with issues related to the development of a framework for autonomously discovering biomass pyrolysis kinetic models from thermogravimetric analyzer experimental data, 34 the usability of waste tire pyrolysis oil along with diesel and biogas dual fuel, 35 carbon emissions, 14 the pyrolysis of some fast-growing tree species, 36 the fire propagation and heat transfer of biomass straw fuel 37 or non-catalytic and catalytic pyrolysis of cellulose. 38 The third main direction of research on the bioenergy topic is focusing on the impact study of the production of bioenergy on the land, on the soil or to develop dedicated energy crops to produce biomass.…”
