摘要

本研究将常压等离子体作为一种新型的无催化剂预处理方法，用于未加工的小麦秸秆（RWS）生物质。该研究探讨了研磨粒度、RWS 含水量和等离子体世代等处理参数对预处理效率的影响。为了了解预处理效率提高背后的机理，研究人员使用了多种分析技术来分析预处理前后 RWS 的物理和化学特性。分析结果表明，等离子体预处理会极大地破坏 RWS 的表面光滑度，并增强木质纤维素结构的分解。这些影响主要归因于脉冲放电产生的活性物质，而不是等离子体预处理过程中伴随的紫外线辐射、酸化或加热作用。

Catalyst‐free pretreatment of raw wheat straw by atmospheric‐pressure pulsed air discharge for enhancement of sugar production

This study presents atmospheric‐pressure plasma as a novel catalyst‐free pretreatment method for raw wheat straw (RWS) biomass. The work explores the effects of processing parameters, such as milled particle size, moisture content of RWS, and plasma generations, on pretreatment efficiency. To understand the mechanisms behind the enhanced pretreatment efficiency, various analysis techniques were used to analyze the physical and chemical properties of RWS before and after pretreatment. The analysis reveals that plasma pretreatment significantly damages the surface smoothness of RWS and enhances the decomposition of lignocellulosic structures. These effects are primarily attributed to the reactive species generated by the pulsed discharge, rather than the accompanying UV radiation, acidification, or heating actions during plasma pretreatment.
