Autohydrolysis-based pretreatments enable extraction of hemicellulose from wood tissue prior to the paper pulp cooking processes enabling their further use as platform chemicals and in material applications. In this study, hot water extraction of birch meal was conducted in a small flow-through system. The combination of high surface area of the milled material with increased driving force induced by constant flow of freshwater, together with fast evacuation of extract, enabled a detailed study of the dissolution process. Based on the findings, deeper insight into acidification and autohydrolysis progress was obtained.

桦木热水提取过程中木材成分的溶解

基于自动水解的预处理能够在纸浆蒸煮过程之前从木材中提取半纤维素，从而使其进一步用作平台化学品和材料应用。在这项研究中，桦木粉的热水提取是在小型流通系统中进行的。研磨后的物料的高表面积与恒定的淡水流量引起的驱动力增加，以及提取液的快速排出相结合，可以对溶解过程进行详细的研究。基于这些发现，获得了对酸化和自动水解进展的更深入的了解。
