The analysis of the potential to improve performance of a methanol synthesis reactor through forced periodical operations by Nonlinear Frequency Response method is presented. The methanol synthesis in an isothermal and isobaric lab-scale CSTR is considered. First, the analysis was performed for single input modulations (in Part I), which showed that significant improvements can’t be achieved. Here, the study is extended to analysis of simultaneous modulations of two inputs. All possible input combinations (6 cases) are analysed and the optimal forcing parameters, maximizing the time-average methanol production, were determined. For all combinations the improvement is possible, but for some cases it is not significant. The highest improvement is predicted for simultaneous modulation of the inlet partial pressure of CO and the inlet volumetric flow rate. This case, for which it is possible to achieve up to 33.51 % of methanol production, is analysed it detail and optimized using multi-objective optimization.

介绍了通过非线性频率响应方法通过强制周期性操作提高甲醇合成反应器性能的潜力分析。考虑了等温和等压实验室规模 CSTR 中的甲醇合成。首先，对单输入调制进行了分析（在第 I 部分），这表明无法实现显着的改进。在这里，研究扩展到分析两个输入的同时调制。分析了所有可能的输入组合（6 种情况），并确定了使时间平均甲醇产量最大化的最佳强迫参数。对于所有组合，改进都是可能的，但在某些情况下并不显着。预计同时调节 CO 入口分压和入口体积流量的改进最大。本案例可以实现高达 33.51% 的甲醇产量，我们对其进行了详细分析，并使用多目标优化进行了优化。
