| 摘 要： | 以微晶纤维素为研究对象，Lewis酸ZnCl2为催化剂，系统考察反应温度、反应时间、氢气压力、ZnCl2用量等对催化液化效果的影响。结果表明：随着反应温度的升高、反应时间的延长、氢气压力的升高、氯化锌用量的增加，纤维素的转化率均有提高；反应温度为320℃、反应时间30min、氢气压力2MPa，催化剂（氯化锌）10％时，纤维素催化液化效果最佳，其转化率可达92．0％。

| Abstract: | Taking micro-fiber as object, Lewis acid ZnCl2 as catalyst, the influences of reaction temperature, reaction time, hydrogen pressure and the ZnCl2 dosage on the cellulose liquefaction effect were studied. The results showed that the conversion rate of cellulose rose along with the increasing of reaction temperature, reaction duration time, hydrogen pressure and the amount of ZnCl2 catalyst. Under the conditions with reaction temperature at 320℃, reaction duration time for 30 min, hydrogen pressure of 2 MPa and the catalyst ZnCl2 dosage as 10 wt%, the liquefaction effect was the best, the conversion ratio could reach 92%. |
