费托合成通常被认为是个动力学控制的反应过程，因此对其热力学平衡的研究很少报道。本文基于 Aspen Plus 软件建立了费托合成产物物性数据库和热力学平衡分析模型，对费托合成的全局和局部热力学平衡进行了详细研究。结果表明：热力学上乙烯较其它长链烯烃更难生成，是解释实验观察乙烯偏低的重要原因；热力学平衡预测的总产物分布及烯烃、烷烃、醇的各组分分布均符合 ASF 分布规律，与实验观察的产物分布非常相似；若假定反应处于局部热力学平衡，则预测的产物分布链增长因子和烯烷比很接近实验观察值；热力学预测的反应条件对产物分布的影响也与实验结果基本一致。由此可见，热力学平衡是影响费托合成产物分布的重要因素，对反应机理研究至关重要。

Fischer-Tropsch synthesis (FTS) has been generally considered as a kinetic-controlled reaction and thus its thermodynamic equilibrium investigations were seldom reported. Based on Aspen Plus software, a physical properties database and a thermodynamic equilibrium model for FTS were established in this study. The simulated results show that ethylene formation is not favored in thermodynamics compared to other long chainα-olefins, which may be a reason to explain the lower ethylene content in experimental product distribution. The estimated product distributions of total hydrocarbons, olefins, paraffins and alcohols are similar to experimental ones and essentially follow Anderson-Schulz-Flory distribution pattern. As a local thermodynamic equilibrium is assumed for the formation of hydrocarbon product, the chain growth parameter and olefin/paraffin ratio are very close to their experimental values under same reaction conditions. Accordingly, thermodynamic equilibrium is highly important

采用室温反相微乳液法制备了3种不同尺寸的花生状微/纳米CaMoO4.基于纳米CaMoO4与块体CaMoO4热力学性质的本质差异,结合化学热力学基本理论及热动力学原理,推导出纳米CaMoO4摩尔表面热力学函数的关系式.在此基础上,采用原位微量热技术获得了花生状微/纳米CaMoO4的摩尔表面热力学函数.结果表明,花生状微/纳米CaMoO4的表面热力学性质变化具有尺寸效应,即随着尺寸的减小,摩尔表面焓、摩尔表面Gibbs自由能、摩尔表面熵均增加.

Mirco/nano peanut-shaped CaMoO4 with three different sizes were prepared via reverse-microemul-sion method at room temperature. Based on the essential difference between thermodynamic properties of nano CaMoO4 and bulk CaMoO4 , the equations for acquiring molar surface thermodynamic functions of nano CaMoO4 were derived via combining the basic theory of chemical thermodynamics with thermokinetic principle. According to the derived equations, molar surface thermodynamic functions such as molar surface enthalpy, molar surface Gibbs free energy and molar surface entropy of the synthesized peanut-like mirco/nano CaMoO4 were successfully gained by in situ microcalorimetry. The results demonstrated that the size has significant in-fluence on surface thermodynamic properties. Along with the size reducing, the molar surface enthalpy, molar surface Gibbs free energy and molar surface entropy increased.
