摘要：
Agro-industrial residues, such as soybean husks, are low-cost and can be converted into products. Therefore, the objective of this work was to evaluate the influence of temperature (230, 260, 300, and 340 °C) and the solvent/feed ratio (40 and 80) in the subcritical water process in semi-continuous mode under soybean husks in fermentable sugar, platform chemicals, bio-oil and hydrochar yields. Contextually, fermentable sugar yield of 7.12 ± 0.43 g/ 100 g Soybean husk and bio-oil yield of 30.72 ± g/ 100 g soybean husk were obtained using the condition at 260 °C, solvent/feed ratio 80. Regarding Higher Heating Value, for bio-oil, the values varied between 22.76 ± 0.14 and 24.86 ± 0.09 MJ.kg−1, and for hydrochar samples it varied between 20.14 ± 0.14 and 30.14 ± 0.11 MJ.kg−1. © 2024 Elsevier B.V.
