This review aims to present an analysis and discussion on the processing of lignocellulosic biomass in terms of biorefinery concept and circular bioeconomy operating at high solids lignocellulosic (above 15% [w/w]) at the pretreatment, enzymatic hydrolysis stage, and fermentation strategy for an integrated lignocellulosic bioprocessing. Studies suggest high solids concentration enzymatic hydrolysis for improved sugars yields and methods to overcome mass transport constraints. Rheological and computational fluid dynamics models of high solids operation through evaluation of mass and momentum transfer limitations are presented. Also, the review paper explores operational feeding strategies to obtain high ethanol concentration and conversion yield, from the hydrothermal pretreatment and investigates the impact of mass load over the operational techniques. Finally, this review contains a brief overview of some of the operations that have successfully scaled up and implemented high-solids enzymatic hydrolysis in terms of the biorefinery concept.
本综述旨在根据生物炼制概念和高固体（高于 15%[w/w]）的循环生物经济，对木质纤维素生物质的处理进行分析和讨论，该高固体适用于预处理、酶解阶段以及用于集成木质纤维素生物加工的发酵策略。研究表明，高固体浓度的酶解有利于提高糖产量，并提出了克服质量传递限制的方法。通过评估质量和动量传递限制，提出了高固体操作的流变学和计算流体动力学模型。此外，该综述论文还探讨了从水热预处理获得高乙醇浓度和转化率的操作进料策略，并研究了质量负荷对操作技术的影响。最后，本综述简要概述了一些根据生物炼制概念成功实现高固体酶解放大和实施的操作。
