| 摘 要： | 比较了近年来文献中甲醇合成反应平衡常数的各种计算方法，采用固定反应器在反应温度为230－270℃和反应压力为5－8MPa的条件下对甲醇合成反应热力进行了实验研究。结果表明，不同计算方法的预测结果存在较大的差异，而采用Reid的热容 数据及SRK方程得到的计算结果与实验结果吻合很好，具有良好的预测能力。

| Abstract: | In this paper, various methods in calculating equilibrium constant of methanol synthesis reaction were reviewed and compared. Experimental study on the thermodynamics of methanol synthesis was conducted in a fixed-bed reactor. The reactor was operated under a temperature range of 230～270℃ and a pressure range of 5～8MPa. The results showed that there is considerable difference among values of the equilibrium constants obtained from different calculation methods. The method employing Reid's thermodynamic data and Soave-Redlich-Kwong (SRK) equation (EOS) can yield result best agreeing with the experimental data. |
