Co-Li2O/Al2O3 catalyst was prepared by equal volume partial impregnation method. On the basis of single factor experiment, process conditions for water reforming of glycerol to hydrogen over Co-Li2O/Al2O3 catalyst were optimized with Box-Behnken mode of response surface method. A mathematical regression model of reaction was established, and the variance and reliability of the model were analyzed. The results show that the suitable conditions are temperature 641 ℃, water alcohol molar ratio23. 28, glycerol liquid space velocity 0. 17 h-1. Under these conditions, predicted hydrogen yield is5. 111 4 mol·mol-1, which is in consistent with actual hydrogen yield of 5. 125 2 mol·mol-1. Therefore, the model is valid and reliable.%采用等体积分步浸渍法制备Co-Li2O/Al2O3催化剂, 在单因素实验基础上, 利用响应面法中的Box-Behnken设计对Co-Li2O/Al2O3催化剂丙三醇水重整制氢条件进行优化, 建立氢产率的二次多项回归模型方程, 并对回归模型进行可信度及方程分析.实验结果表明, 当反应温度641℃, 水醇物质的量比23. 28, 丙三醇液空速0. 17 h-1时, 氢产率最高, 预测最大值5. 111 4 mol·mol-1, 与实测值5. 125 2 mol·mol-1基本相符, 建立模型有效可靠.
