| 摘 要： | 对异丁烷脱氢制异丁烯反应进行了较为详细的热力学分析，得到了不同反应温度下的标准摩尔焓变、标准摩尔吉布斯自由能变和标准平衡常数值，同时分析了温度、压力、氢/烃及惰性气/烃摩尔比对反应平衡的影响。结果表明，异丁烷脱氢属强吸热反应，进料的反应吸热量高达122 kJ/mol；反应温度和压力是影响异丁烷脱氢过程的2个主要因素，提高反应温度、降低反应压力均可显著提高异丁烷的平衡转化率；降低氢/烃摩尔比或提高惰性气/烃摩尔比也可以在一定程度上提高异丁烷的平衡转化率。

| Abstract: | Thermodynamic analysis on dehydrogenation of isobutane to isobutene was carried out in detail.Thermodynamic data,including standard molar enthalpy change,standard molar Gibbs free energy change and standard equilibrium constant at different temperatures were calculated.The effects of temperature,pressure,molar ratio of hydrogen to paraffin and inert gas to paraffin on the thermodynamic equilibrium of the reaction were discussed.The results showed that reaction temperature and pressure were the main factors ... |
