| 摘 要： | [目的]优化玉米秸秆液化工艺。[方法]以液化率为指标，通过单因素试验筛选出适宜的液化剂和催化剂，并通过正交试验优化液化工艺。[结果]EC和EC＋EG的液化效果较好，液化60min时液化率就接近于踟％；EG的液化效果较差，液化100min时液化率才达到70％。以浓硫酸为催化剂，EC和EC＋EG为液化剂的玉米秸秆的液化率接近80％；以磷酸为催化剂二者的液化率接近50％；以浓盐酸为催化剂，EC为液化剂的玉米秸秆的液化率不到24％，EC＋EG为液化剂的玉米秸秆的液化率只有11％；以碳酸钠和氢氧化钠为催化剂的玉米秸秆的液化率不到5％。较优液化工艺为添加3％催化剂在160℃下液化1．0h，此条件下玉米秸秆的液化率为90．56％。[结论]液化温度是影响液化率的最主要因素，其次是催化剂用量，影响最小的是液化时间。

| Abstract: | [Objective] The study aimed to optimize the liquefaction technology of corn stalks.[Method] With liquefaction rate as index,the suitable liquefier and catalyst were screened out through single factor experiments and the liquefaction technology was optimized through orthogonal experiment.[Result] The liquefaction effects of EC and EC+EG were better and their liquefaction rates were close to 80% after liquefaction for 60 min.The liquefaction effect of EG was worse and its liquefaction rate did not reach 70% t... |
