摘要：计算了甲烷无氧芳构化中的各反应标准摩尔吉布斯自由能和标准平衡常数,计算结果表明,温度是影响反应热力学的重要因素,较高温度有利于甲烷的转化和芳烃的生成,但温度太高将有较多的积炭生成,要想得到较高的芳烃收率,需要一个合适的反应温度。
The standard molar Gibbs free energies and equilibrium constants of reactions concerned in methane aromatization under non-oxidative condition were calculation. The results showed that the temperature was the key factor which affects the reaction thermodynamics. The higher temperature was propitious to the conversion of methane and the production of aromatic hydrocarbon, however, the more carbon deposit was produced if the temperature was too high. A suitable reaction temperature was prerequisite for obtaining a higher yield of aromatic hydrocarbon.
