The optimization of cellulose hydrolysis in a microwave reactor (MWR) in the presence of bamboo-derived sulfonated catalyst was studied through a response surface methodology (RSM). Three-factor and three-level Box-Behnken design was employed to study the effects of hydrolysis temperature, hydrolysis time, and catalyst to substrate ratio on total converted cellulose and glucose yield. Quadratic models were proposed for both responses. The respective analysis of variance (ANOVA) showed that the proposed quadratic models could be used to navigate the design space. The optimum hydrolysis conditions were found to be hydrolysis temperature of 175 °C, hydrolysis time of 74 min, and catalyst to substrate ratio of 1.25 g/g. Under these conditions, the total amount of converted cellulose and glucose yield was 79.4% and 61.1%, respectively. Validation of the models indicated that the predicted values were in a good agreement with the experimental results.

响应面法优化微波反应器中生物质衍生的磺化催化剂存在下纤维素的水解

通过响应面法(RSM)研究了存在竹衍生磺化催化剂的微波反应器(MWR)中纤维素水解的优化。采用三因素和三级Box-Behnken设计研究水解温度,水解时间和催化剂与底物比例对总转化纤维素和葡萄糖产率的影响。两种响应都提出了二次模型。各自的方差分析(ANOVA)表明,所提出的二次模型可用于导航设计空间。发现最佳的水解条件是水解温度为175℃,水解时间为74分钟,催化剂与底物的比例为1.25g / g。在这些条件下,转化纤维素的总量和葡萄糖产率分别为79.4%和61.1%。
