【摘要】 因子实验研究结果表明,显著影响麦草酸催化乙醇法制浆的外界因子是乙醇体积分数、蒸煮温度、催化剂用量和保温时间。在此基础上,采用响应面建立了细浆得率的二次多项数学模型,分析了模型的有效性及各因子的交互作用和最佳水平范围;优化出细浆得率取得最大值的外界条件为:乙醇体积分数65%,蒸煮温度190℃,催化剂用量0．8%,保温时间52．5min。更多还原

【Abstract】 The results of factorial experiment showed that the significant external factors affecting acid-catalytic ethanol pulping of wheat straw were ethanol concentration,pulping temperature,acid dosage and temperature holding time.Based on the results,response surface methodology (RSM) was employed to establish a second order quadratic equation for pulp screened yield,The applicability of the model equation for predicting the optimum response values was verified effectively by the validation data.By analyzing the response surface plots and their corresponding contour plots as well as solving the quadratic equation,the optimum process parameters for pulping were obtained as:ethanol concentration 65%,pulping temperature 190℃,acid dosage 0.8% and temperature holding time 52.5min.更多还原
