Abstract

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.

亚临界水半连续液化大豆壳的研究

农业工业残留物，如大豆外壳，成本低，可以转化为产品。因此，这项工作的目的是评估温度（230、260、300和340℃）和溶剂/料比（40和80）在半连续模式下在大豆壳下的亚临界水过程中对可发酵糖、平台化学品、生物油和碳氢化合物产量的影响。在260℃、料液比为80的条件下，可发酵糖得率为7.12±0.43 g/ 100 g，生物油得率为30.72±g/ 100 g。对于较高的热值，生物油的热值在22.76±0.14 ~ 24.86±0.09 MJ之间。对于碳氢化合物样品，其变化范围在20.14±0.14和30.14±0.11 MJ.kg−1之间。

期刊介绍： The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics. Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
