| 摘 要： | 研究了玉米秸秆在多羟基醇中的液化反应,结果表明液化剂用量、反应温度、反应时间以及催化剂用量等条件对玉米秸秆液化反应有较大的影响。以聚乙二醇和甘油的混合物为液化剂,在温度为160℃、时间为30 min、液化剂用量为玉米秸秆质量的4.5倍、浓硫酸用量为液化剂用量的3.25%时,液化率可达到90%,所得到的玉米秸秆液化产物羟值为380 mg/g,黏度为353 mPa·s。同时通过红外光谱分析了玉米秸秆液化的有关机理。

| Abstract: | The liquefaction of corn stalk in polyhydric alcohol was studied. The results showed that dosage of liquefaction solvent, reaction temperature, reaction time, and catalyst all have significant effect on liquefaction. In the condition of temperature 160 ℃, reaction time 30 min, ratio of solvent to corn stalk 4.5, and ratio of catalyst to liquefaction solvent 3.5%, liquefaction rate would reach 90%, hydroxyl number of liquefied product was 380 mg/g and the viscosity of liquefied product was 353 mPa·s. Finally the relative mechanism of corn stalk liquefaction was investigated by FTIR spectroscopy. |
