Instant catapult steam explosion (ICSE) offers enormous physical force on lignocellulosic biomass due to its extremely short depressure duration. In this article, the response surface methodology was applied to optimize the effect of working parameters including pressure, maintaining time and mass loading on the crystallinity index and glucose yield of the pretreated corn stover. It was found that the pressure was of essential importance, which determined the physical force that led to the morphological changes without significant chemical reactions, and on the other hand the maintaining time mainly contributed to the thermo-chemical reactions. Furthermore, the pretreated biomass was assessed by scanning electron microscope, X-ray diffraction and Fourier transform infrared spectra to understand mechanisms underlying the ICSE pretreatment.
瞬时弹射蒸汽爆炸（ICSE）由于其极短的减压持续时间，为木质纤维素生物质提供了巨大的物理力。在本文中，响应面法被应用于优化工作参数（包括压力、保持时间和质量负荷）对预处理玉米秸秆结晶度指数和葡萄糖产率的影响。结果表明，压力是至关重要的，它决定了导致形态变化而没有显著化学反应的物理力，另一方面，保持时间主要有助于热化学反应。此外，通过扫描电子显微镜、X 射线衍射和傅里叶变换红外光谱对预处理后的生物质进行了评估，以了解 ICSE 预处理的作用机制。
