Biomass pretreatment and conversion are crucial for sustainable development, but lack information on equipment that ensures effective mass transfer and easy biomass separation post-process. This work introduces a novel basket reactor with a stationary bed (StatBioChem) for biomass processing using deep eutectic solvents (DESs). We compared the delignification efficiencies of soft and hard biomass samples processed in the StatBioChem reactor, a stirred tank reactor (STR), and a commercial SpinChem® reactor. The StatBioChem design allowed DES to flow evenly through biomass in the basket, achieving the highest delignification degree, particularly for hard biomass. This effect was not observed in the SpinChem® basket reactor. High delignification led to increased glucose yields in subsequent enzymatic hydrolysis. The StatBioChem effectively combines the simplicity and efficiency of an STR with the ease of solvent recovery typical of basket reactors.

新型固定篮式反应器，用于使用深共熔溶剂进行有效的生物质脱木素


生物质预处理和转化对于可持续发展至关重要，但缺乏有关确保有效传质和易于生物质后处理的设备信息。这项工作介绍了一种带有固定床的新型篮式反应器 （StatBioChem），用于使用深共熔溶剂 （DES） 进行生物质加工。我们比较了在 StatBioChem 反应器、搅拌罐式反应器 （STR） 和商用 SpinChem® 反应器中处理的软质和硬质生物质样品的脱木素效率。StatBioChem 设计使 DES 能够均匀地流过篮子中的生物质，达到最高的木素化程度，特别是对于硬质生物质。在 SpinChem® 篮式反应器中没有观察到这种效果。高脱木素导致随后酶水解中的葡萄糖产量增加。StatBioChem 有效地结合了 STR 的简单性和效率，以及篮式反应器典型的溶剂回收简便性。
