摘要

选择FeCl3和Fe(NO3)3两种无机盐作为催化剂，考察了它们对玉米秸秆水解的影响，结果表明Fe(NO3)3是水解半纤维素最有效的催化剂之一。研究了不同温度下Fe(NO3)3催化玉米秸秆水解反应的动力学。结果表明，两馏分模型很好地拟合了Fe(NO3)3催化半纤维素水解反应，并采用牛顿法进行非线性回归，得到了该模型的动力学参数。用经典Arrhenius方程计算得到玉米秸秆中半纤维素的水解活化能为91.79 kJ/mol。最佳预处理条件为0.05 mol/L Fe(NO3)3，预处理时间为16.5 min，预处理温度为150℃，木糖收率为初始木聚糖的91.3%。

Characterization of the hydrolysis of corn stover catalyzed by inorganic Fe salt for biogas production

Two inorganic salts, FeCl₃ and Fe(NO₃)₃, were chosen as catalysts to determine their effects on the hydrolysis of corn stover, and the results indicated that Fe(NO₃)₃ was one of the most efficient catalyst for the hydrolysis of hemicelluloses. The kinetics of the hydrolysis reaction of corn stover catalyzed by Fe(NO₃)₃ were investigated at different temperatures. The results showed that two-fraction model fitted very well the hydrolysis reaction of hemicelluloses catalyzed by Fe(NO₃)₃, and the kinetic parameters for this model were obtained by nonlinear regression using the Newton's method. The activation energies for the hydrolysis of hemicelluloses in corn stover was 91.79 kJ/mol calculated by the classic Arrhenius equation. Optimum pretreatment conditions were 0.05 mol/L Fe(NO₃)₃ at 150 °C for 16.5 min, which obtained the maximum xylose yields 91.3% of initial xylan.
