摘要: 采用微波预处理技术,探讨在H2SO4、HCl、H2O、NaOH、NH3·H2O 5种吸波介质中纤维素化学成分、结构的不同变化,及对后续厌氧发酵产氢的影响。结果表明:经微波处理后的废纸,其纤维水解率、产氢量均高于未处理底物;利用微波-H2O处理产氢率最高,达44.6mL氢气(以挥发性固体含量计算),而未处理对照组每克纤维只产13.7mL氢气。纤维原料经微波处理后,纤维结晶程度降低,增加了底物的可及性,但并未发生化学结构的变化。

Abstract: Pretreatment has a significant influence on hydrogen production from cellulosic materials by anaerobic fermentation. Microwave heating can change the crystal line structure of the fiber material to increase the hydrolysis degree of fiber. In this study, microwave pretreatments with H2SO4, HCl, H2O, NaOH and NH3·H2O respectively were studied. The results showed that through microwave treatment of waste paper, the fiber hydrolysis rates during hydrogen production were higher than those of the untreated. Among them, it produced the highest hydrogen production rate of 44.6mL hydrogen from 1g fiber(calculates by volatile solid,SV) after the treatment of microwave-NH3·H2O, while the untreated group produced only 13.7mL hydrogen/g fiber. Through microwave treatment of fiber material, fiber crystallinity was decreased, the accessibility of substrate was increased, but no change of chemical structure was found.
