The addition of static mixers within reactors leads to higher productivity of a process and an additional increase in mass and energy transfer. In this study, we developed millireactors with static mixers using stereolithography, an additive manufacturing technology. Computational fluid dynamics (CFD) simulations were conducted to study the flow, identify potential dead volumes, and optimize the design of the millireactors. We produced five millireactors with various static mixers and one tubular reactor without static mixers, which served as a reference. The Fenton reaction was performed as a model reaction to evaluate the performance of the millireactors. We observed that some of the reactors with static mixers had air plugs that created a significant dead volume but still exhibited higher conversions compared to the reference reactor. Our results demonstrate the potential of stereolithography for producing intricate millireactors with static mixers, which can enhance the productivity of chemical processes.
在反应器内添加静态混合器可提高工艺的生产率，并进一步增加质量和能量传递。在本研究中，我们使用增材制造技术——立体光刻法开发了带有静态混合器的微反应器。进行了计算流体动力学（CFD）模拟，以研究流动情况、识别潜在的死体积并优化微反应器的设计。我们制造了五个带有不同静态混合器的微反应器和一个不带静态混合器的管式反应器作为参考。以芬顿反应作为模型反应来评估微反应器的性能。我们观察到，一些带有静态混合器的反应器存在气栓，这造成了显著的死体积，但与参考反应器相比，其转化率仍然更高。我们的结果证明了立体光刻法在制造带有静态混合器的复杂微反应器方面的潜力，这种微反应器可以提高化学工艺的生产率。
