Biomass hydrolysate from autohydrolysis pretreatment was used for furfural production considering it is in rich of xylose, xylo-oligomers, and other decomposition products from hemicellulose structure. By using the vapor-releasing reactor system, furfural was protected from degradation by separating it from the reaction media. The maximum furfural yield of 73% was achieved at 200 °C for biomass hydrolysate without the use of the catalyst. This is because the presence of organic acids such as acetic acid in hydrolysate functioned as a catalyst. According to the results in this study, biomass hydrolysate with a vapor-releasing system proves to be efficient for furfural production. The biorefinery process which allows the separation of xylose-rich autohydrolysate from other parts from biomass feedstock also improves the overall application of the biomass.
考虑到自水解预处理的生物质水解产物富含木糖、木寡糖和其他来自半纤维素结构的分解产物，因此将其用于生产糠醛。通过使用蒸汽释放反应器系统，将糠醛与反应介质分离，从而防止其降解。在不使用催化剂的情况下，生物质水解产物在 200°C 时获得了 73%的最大糠醛产率。这是因为水解产物中存在乙酸等有机酸，它们起到了催化剂的作用。根据本研究的结果，使用蒸汽释放系统的生物质水解产物可有效地用于生产糠醛。生物炼制工艺允许将富含木糖的自水解产物与生物质原料的其他部分分离，这也提高了生物质的整体应用。
