摘要(Abstract)：

糠醛渣是玉米芯制糠醛剩下的废渣,量大且未得到有效利用。糠醛渣主要含有纤维素和木质素,是制备乙酰丙酸的理想原料。以高温液态水为反应介质,以稀硫酸为催化剂,考察了液固比、酸浓度、反应时间和反应温度对糠醛渣降解制备乙酰丙酸的收率的影响,得到了糠醛渣制备乙酰丙酸的适宜工艺条件:固液比1:10、酸浓度2%、温度180℃、反应时间2 h,此时乙酰丙酸的收率达到66.6%。另外,以一级连串反应动力学方程对实验数据进行拟合,得到纤维素水解的表观活化能为122.7 k J×mol~(-1),葡萄糖降解生成乙酰丙酸的表观活化能为107.6 k J×mol~(-1)。

关键词(KeyWords)： 糠醛渣;乙酰丙酸;高温液态水;稀硫酸
