Abstract Developing efficient catalytic packing for reactive distillation can push its application greatly forward. Structured Corrugation SiC Foam Packing is considered an attractive candidate with the rapid development of the coating method. However, liquid flow behavior on the packing and its radial and axial dispersion coefficients remain unclear. We studied herein liquid renewal on the structured corrugation SiC foam packing sheet by photography. The images revealed that the liquid could be constantly refreshed on most of the wetted area and the process can be categorized into two stages by the renewal rate. Effects of liquid flow rate, viscosity, and surface tension on the renewal process were investigated. The renewal results highlight the applicability of the foam packing at low liquid load. Furthermore, axial and radial dispersion coefficients of two foam packing sheets with different pore sizes were characterized, and comparisons with KATAPAK-S showed that the foam packing has better liquid dispersion ability.

结构化波纹碳化硅泡沫填料片材液体更新及其分散系数的实验研究

摘要 开发高效的反应精馏催化填料可以极大地推动其应用。随着涂层方法的快速发展，结构波纹碳化硅泡沫填料被认为是一种有吸引力的候选材料。然而，填料上的液体流动行为及其径向和轴向分散系数仍不清楚。我们通过摄影研究了结构化波纹 SiC 泡沫填料片上的液体更新。图像显示液体可以在大部分润湿区域不断更新，并且该过程可以根据更新率分为两个阶段。研究了液体流速、粘度和表面张力对更新过程的影响。更新结果突出了泡沫填料在低液体负载下的适用性。此外，
