以松木木屑为原料,在自制的间歇式水解反应器中,考查稀硫酸催化纤维素水解的反应情况。通过分析酸浓度对纤维素水解的影响规律,以反应物纤维素作为定量标准,建立包含酸浓度影响的动力学方程;通过数值模拟,得到动力学方程中的参数以及酸催化纤维素水解的活化能,动力学方程表示为:-dC C dt=3.68×1010×[H+]1.6×exp-107.1×103()RT×C C(mol/L·s);通过实验检验和统计检验认为,该动力学方程是高度适定的,可准确描述木屑中纤维素的水解规律。 Pine wood sawdust as raw material, in a self-made batch hydrolysis reactor, to examine the reaction of dilute sulfuric acid catalyzed hydrolysis of cellulose. By analyzing the influence of acid concentration on the hydrolysis of cellulose, the kinetic equation including the effect of acid concentration was established by using the reactant cellulose as a quantitative standard. Through the numerical simulation, the parameters in kinetic equation and the activation of acid-catalyzed cellulose hydrolysis The kinetic equation can be expressed as: -dC C dt = 3.68 × 1010 × [H +] 1.6 × exp-107.1 × 103 () RT × CC (mol / L · s); through experimental and statistical tests, The equation of learning is highly appropriate and can accurately describe the hydrolysis of cellulose in wood chips.
