Abstract
- This study aimed to optimize the production of bio-oil from Leucaena leucocephala wood using a fluidized bed reactor. Response surface methodology was used to optimize the fast pyrolysis through three operational parameters: pyrolysis temperature, nitrogen flow rate, and temperature of the first condensation stage. The optimum conditions obtained for bio-oil production were 500 °C, 26.4 L min<superscript>–1</superscript>, that is, about 3.3 times the minimum fluidization flow, and 80 °C, respectively. The bio-oil obtained under optimum conditions was of good quality and did not require further treatment. Physical properties of the bio-oil were analysed according to ASTM D7544-12. In addition, the chemical composition of the non-condensed gases and bio-oil were identified using GC–MS. The non-condensed gases were found to contain mainly ketones and lignin derivatives, while the bio-oil contained cyclic ketones, alcohol ethers, aromatic alcohols, and lignin derivatives. The study found that increasing the pyrolysis temperature did not significantly increase the yield of H<subscript>2</subscript> and CO for syngas production. Regarding the solid obtained, a large amount of unreacted material (66.7 wt.%) is generated at 400 °C, and as the temperature is increased, a high-quality biochar is obtained. [ABSTRACT FROM AUTHOR]
