Abstract This study investigated the performance of microreactor system in conducting the oxidation of KA oil with nitric acid through mathematical models. Experiments were also carried out via a self-designed microreactor system. Two one-dimensional (1D) pseudohomogeneous models and a two-dimensional (2D) reactor model were developed according to the mass balance and power law kinetics. The calculated results based on different models were compared with experimental data to evaluate the model reliability. The results showed that 1D axial dispersion model and 2D reactor model exhibited comparable accuracy in predicting the conversion of the intermediates, while 2D reactor model was more accurate in predicting the yield of products. With the 2D reactor model, the sensitivity study showed that temperature was the most sensitive parameter. Further studies on the effect of different factors were carried out via the developed model to shed lights on the design and operation of industrial-scale microreactors.

KA油氧化合成己二酸微反应器的数值模拟

摘要 本研究通过数学模型研究了微反应器系统在硝酸氧化KA油中的性能。还通过自行设计的微反应器系统进行了实验。根据质量平衡和幂律动力学开发了两个一维 (1D) 拟均质模型和一个二维 (2D) 反应器模型。将基于不同模型的计算结果与实验数据进行比较，以评估模型的可靠性。结果表明，一维轴向分散模型和二维反应器模型在预测中间体转化率方面表现出相当的准确性，而二维反应器模型在预测产品产率方面更准确。对于二维反应器模型，敏感性研究表明温度是最敏感的参数。
