By means of uniform and rotating regression design optimal steam explosion conditions for the ligno-cellulosic waste,namely the fibrous trash from material preperation of a paper mill ,and the effects of steam pressure,holding time and acid addition on hemicellulose recovery and enzymatic susceptibility of cellulosic residue were investigated. It was found that 1. 5-1. 6 MPa,17- 18 min and with no acid addition were proper conditions for both. The mechanism of steam explosion was preliminarily studied.

采用均匀设计和旋转回归设计序贯形式,对纤维性废物——造纸厂麦秸备料废渣的蒸汽爆碎预处理条件进行了优化。发现蒸汽爆碎条件对纤维废物的纤维素可酶解性和半纤维素抽提得糖率的影响明显不同。综合考虑两者,认为罐压为1.5~1.6MPa,维持17~18min后喷放为最佳条件。初步分析了汽爆预处理的机理。此外对影响汽爆材料中可溶性半纤维素水解物水抽提的因素进行了研究。发现在汽爆材料浓度为15%和热水抽提条件下,抽提3~4次可达到较理想的抽提效果。采用重复式或连续式抽提工艺,可获得糖浓度不同(16.0~47.7g/L)的水抽提液,其糖组成分析显示,木糖占总糖的85.9%,单糖与寡糖之比为1:9。

Bagasse and chopped poplar wood were used as substrates for studying the effects of pretreat-ments on enzymatic hydrolysis of cellulose. Pretreatments by acid ,alkali and steam-explosion and enzymatichydrolysis at 50℃ for 24 h were adopted in the experiments, Pretreated materials were analysed by de-terming total sugar,sugar fraction and lignin contents in the hydrolyzates. The crystallinity of bagasse andpoplar before and after pretreatments was estimated by X-ray diffraction。 Effects of different pretreatrnentson variations of composition and enzymatic hydrolysis of cellulosic materials were seen from the results andthe total utilization of biomass of these materials was tentatively discussed.
