喷射环流反应器显示出特定的特性，例如强烈的混合和有效的气体分散，这使它们成为均相多相催化中传统反应器概念的有趣替代方案。本文研究了多相催化中特定功率输入和常见添加剂对小型喷射环流反应器导流管和提升管段气泡尺寸分布的影响，并阐明了循环过程中的聚结。最后计算界面面积并与标准反应器进行比较。
Jetloop reactors show specific properties, such as intensive mixing and effective gas dispersion, which make them an interesting alternative for conventional reactor concepts in homogeneous multiphase catalysis. This contribution investigates the effect of specific power input and common additives in multiphase catalysis on bubble-size distributions in the draft tube and riser section of a miniplant-scale jetloop reactor and elucidates the coalescence during circulation. Finally interfacial areas are calculated and compared to standard reactors.
