摘要：结合单因素试验分析,以液比、温度、保温时间为自变量,根据Box-Benhnken实验设计原理,用DesignExpert软件进行响应面分析(RSA),得出桉木半纤维素自催化水解工艺优化条件:液比13.81,最高温度184.62℃,保温时间103.01 min,在此条件下的最高响应值为0.1331 g/g。为验证响应面分析法(RSA)的可靠性,采用液比14,最高温度185℃,保温时间100 min,实测优化条件下每克绝干原料还原糖提取量的平均值为0.1311 g/g,半纤维素还原糖提取率高达61.24%,且在误差允许的范围内,与理论预测值基本相符。
The integrated forest biorefinery based on forestry biomass can transform more wood components into chemical products and energy carriers to reach the more efficiently industrial use of biomass resources. And the clean and high efficient utilization of hemicelluloses has always been a key matter for researchers. Combining with single-factor tests, based on the Box-Benhnken experimental design principles, the RSA experiment was designed by the Design- Expert software under 3 independent variables, including liquid-solid ratio, the highest temperature and holding time. The optimal condition of auto-hydrolysis process of eucalyptus hemicellulose was got, the liquid-solid ratio of 13.81, the maximum temperature of 184.62 ℃, and the holding time of 103.01 min, with a maximum response value of 0.1331 g/g in this condition. In order to verify the reliability of the optimal condition, 4 parallel experiments under the actual conditions including liquid-solid ratio of 14, the highest temperature of 185 ℃ and holding time of 100 min were reached, and an average amount of 0.1311 gram extractive reducing sugar per gram oven dry raw materials and 61.24% hemicelluloses can be got with the form of reducing sugar. The optimal results are agreeable with theoretical predictions within the range of the allowable error.
