3D-printed catalyst structures have the potential to broaden reactor operating windows. However, the hydrodynamic aspects associated with these novel catalyst structures have not yet been quantified in detail. This work applies a recently introduced noninvasive, instantaneous, whole-field concentration measurement technique based on infrared transmission to quantify the rate of transverse gas dispersion in 3D-printed logpile structures. Twenty-two structural variations have been investigated at various operating conditions, and the measured transverse gas dispersion has been correlated to the Péclet number and the structures’ porosity and feature size. It is shown that staggered configurations of these logpile structures offer significantly more tunability of the dispersion behavior compared to straight structures. The proposed correlations can be used to facilitate considerations of reactor design and operating windows.

使用无创红外传输技术对 3D 打印测井桩结构中的气体扩散进行实验量化

3D 打印的催化剂结构有可能拓宽反应器的操作窗口。然而，与这些新型催化剂结构相关的流体动力学方面尚未被详细量化。这项工作应用最近推出的基于红外传输的无创、瞬时、全场浓度测量技术来量化 3D 打印的测井桩结构中的横向气体扩散速率。已经在不同的操作条件下研究了 22 种结构变化，并且测量的横向气体扩散与 Péclet 数以及结构的孔隙率和特征尺寸相关。结果表明，与直线结构相比，这些测井桩结构的交错配置显着提高了色散行为的可调性。
