Optimisation and characterisation of bio-oil produced by Acacia mangium Willd wood pyrolysis

Optimization and Characterization of Wood Vinegar Produced by <i>Shorea laevis</i> Ridl Wood Pyrolysis

“…The higher wood vinegar yield at a higher temperature (Table 2) might have been due to the complete pyrolysis at these temperatures. Similar results were reported by Islam et al [8] and Crespo et al [6].…”

“…The calculated maximum wood vinegar yield was 30.31%. Factors contributing to maximize wood vinegar yield were pyrolysis temperature and particle size [6]. The effect of pyrolysis time on wood vinegar yield was negligible in this study.…”

“…Crespo et al [6] observed that wood vinegar yield from Acacia mangium ranged from 24.88-32.94% and that a high wood vinegar yield was obtained at higher temperatures of nearly 500 °C. In the present experiments, at the lower pyrolysis temperature of 350 °C, the sawdust could not be completely decomposed, so that lower wood vinegar yields were obtained.…”

“…had insecticidal activity against Rhopalosiphum padi. Various studies have been reported about the effects of different types of wood, wood particle size (particle size), pyrolysis temperature and time on the yield of wood vinegar [4][5][6][7].…”

“…RSM has been successfully used to maximize wood vinegar yield from Euphorbia rigida [13] and palm kernel [14] by fast pyrolysis. Optimization of operating parameters and process of wood vinegar from Acacia mangium was studied by Crespo et al [6], who found that optimum pyrolysis conditions were obtained at a temperature, heating rate, and particle size of 499.57 °C, 12 °C min -1 and 0.46 mm, respectively, for a yield of 33.13%. Ngo et al [14] used the RSM to study the effect of feedstock feed rate, the particle size of biomass, the temperature of pyrolysis, and residence time on the fast pyrolysis of palm kernel; the optimal wood vinegar yield was 49.50%.…”
