摘要

本研究探讨了预处理和酶解侧流的使用以及木质纤维素纳米纤维的转化。以蒸汽爆破部分酶解的硬木纸浆和有机溶剂预处理的软木纸浆为原料，通过微流化法制备了木质纤维素纳米纤维。估计用于纤颤的能量，以检查LCNF生产的能量消耗水平。在干料基础上，硬木LCNF生产和软木LCNF生产的纤颤过程能耗分别约为7040-14080 kWh/t和4640 kWh/t。研究了阔叶木和软木制备的LCNFs的形态、尺寸及其悬浮液的稳定性和流变性能。

From biorefineries to bioproducts: conversion of pretreated pulp from biorefining streams to lignocellulose nanofibers

This study investigates the use of pretreatment and enzymatic hydrolysis side streams and conversion to lignocellulose nanofibers. We used a steam-exploded and partial enzymatic hydrolyzed hardwood pulp and an organosolv pretreated softwood pulp to prepare lignocellulose nanofibers (LCNF) via microfluidization. The energies applied on fibrillation were estimated to examine the energy consumption levels of LCNF production. The energy consumptions of the fibrillation processes of the hardwood LCNF production and the softwood LCNF production were about 7040-14080 kWh/ton and 4640 kWh/ton on a dry material basis, respectively. The morphology and dimension of developed hardwood and softwood LCNFs and the stability and rheological behavior of their suspensions were investigated and are discussed.
