Abstract

Periodic open cellular structures (POCS) represent a promising new class of structured internals as next-generation catalyst supports in reactors or structured packing elements in separation columns. POCS feature a well-defined morphology and can be fabricated with high reproducibility even for complex geometries by means of additive manufacturing. This results in a uniform and easily controllable flow field, which allows for adjusting the heat and mass transport processes to realize optimal process conditions. We review the fundamentals of POCS, including design and manufacturing as well as transport phenomena for single- and multiphase systems. Moreover, we review recent POCS applications in reaction and separation processes and consider promising future application fields. The exceptional transport characteristics of POCS facilitate the design of highly efficient, flexible, resilient, and safe processes, which is key for achieving process intensification toward a sustainable future.

化学工程中的周期性开放细胞结构：催化和分离过程中的应用

周期性开放式蜂窝结构（POCS）是一类前景广阔的新型结构内构件，可用作反应器中的下一代催化剂载体或分离柱中的结构填料元件。POCS 具有明确的形态特征，即使是复杂的几何形状，也能通过增材制造技术以较高的可重复性制造出来。这使得流场均匀且易于控制，从而可以调整热量和质量传输过程，实现最佳工艺条件。我们回顾了 POCS 的基本原理，包括设计、制造以及单相和多相系统的传输现象。此外，我们还回顾了 POCS 在反应和分离过程中的最新应用，并探讨了前景广阔的未来应用领域。POCS 的优异传输特性有助于设计出高效、灵活、弹性和安全的工艺，这是实现工艺集约化、迈向可持续未来的关键所在。
