| 摘 要： | 应用最小自由能原理,对有固态炭存在下的乙醇氧化重整制氢反应系统进行热力学分析,讨论了温度、压力、水醇比、氧醇比对该体系平衡组成的影响。计算结果表明,压力对产物组成影响不大。在确定最优操作条件时,采用平衡前后系统总焓变为零的方法,经计算当水醇比为6、氧醇比为0.9时,平衡温度为1008K,可以得到比较理想的平衡组成。

| Abstract: | The principle of free-energy minimization is used to analyze the thermodynamics of ethanol oxidation reforming for hydrogen production. The effects of reaction temperature, pressure, H2O/C2H5OH and O2/G2H5OH molar ratios of the feed are discussed, and the solid carbon is also considered. The results show that the effect of pressure is not significant. The optimum operation conditions can be obtained when the net enthalpy change from feed to product is zero. When the H2O/G2H5OH molar ratio is 6 and O2/C2H5OH molar ratio is 0.9 in the feed, the equilibrium temperature is 1008K, and a favorable equilibrium composition of products can be obtained. |
