Steam explosion (SE) pretreatment and sequentially subcritical water hydrolysis (SWH) was studied. Industrially, there is an advantage in using this process strategy, since it uses the same equipment and instrumentation, without the need to transport the raw material in separate stages. The influence of severity factors (SF) (2.75, 3.05, and 3.35) and solvent used (distilled water and 0.5 % w/w of H2SO4) were evaluated in the SE efficiency. SWH was perform in integrated processing using the best pre-treatment conditions. The influence of temperature (230 and 260 °C) and the solvent/feed ratio (40 and 80) were considered. The integrated system resulted in a FS yield of 19.19 ± 0.49 g/ 100 g SH, for a condition Integrated 230 °C, S/F-40, a FS yield 3.3 times greater than that obtained in the same condition with untreated soybean hulls, demonstrating the advantage of perform the process under this operating strategy (SE + SWH)

蒸汽爆炸预处理大豆壳的亚临界水解：高压集成工艺策略


研究了蒸汽爆炸 （SE） 预处理和顺序亚临界水解 （SWH）。在工业上，使用这种工艺策略有一个优势，因为它使用相同的设备和仪器，而无需在单独的阶段运输原材料。评估了严重程度因子 （SF） （2.75、3.05 和 3.35） 和所用溶剂 （蒸馏水和 0.5 % w/w 的 H 2 SO 4 ） 对 SE 效率的影响。SWH 使用最佳预处理条件进行综合加工。考虑了温度（230 °C 和 260 °C）和溶剂/进料比（40 °C 和 80）的影响。在积分 230 °C、S/F-40 的条件下，集成系统的 FS 产量为 19.19 ± 0.49 g/100 g SH，FS 产量是在相同条件下使用未经处理的大豆壳获得的产量的 3.3 倍，证明了在这种操作策略 （SE + SWH） 下执行工艺的优势
