本文以乙烯在银催化剂上的选择氧化反应作为模型反应,通过实验研究证明,在适宜的周期操作条件下,反应器的操作特性优于最佳稳态.在此基础上,从反应机理、动态响应和周期操作特性相互关系的角度,对这一重要体系作了进一步的研究,从而在理沦上对这一体系在周期操作下时均性能的改善作了解释. In this paper, the selective oxidation reaction of ethylene on silver catalyst is taken as a model reaction, and the experimental results show that the operating characteristics of the reactor are better than the optimum steady state under the suitable periodic operating conditions.On this basis, the reaction mechanism, Response and the periodic operating characteristics of the relationship between the perspective of this important system was further studied, so as to justify the system in the cyclical operation of the average performance under the time explained.
