In this paper, the monophasic catalytic reaction in the microreactor is studied. Several factors that may affect the catalytic reaction are discussed, including the pressure drop, the size of catalyst particles, and the channel structure. Finally, some important conclusions can be reached. The change of pressure drop has an effect on the reaction. For example, the C3H6 conversion rate is 62.88% when the pressure drop is 8[Formula: see text]atm, and the C3H6 conversion rate is 61.78% when the pressure drop is 11[Formula: see text]atm. The effect of the change particle radius is not obvious on the reaction. Enhancing the mixing of substances before entering the reaction domain is helpful to the catalytic reaction. There are different substances concentration in catalyst particles at different positions in microreactors. But from the surface to the inside of catalyst particles, the substances concentration has a clear change rule.

填充床微反应器的单相反应：传质和反应的表征

本文研究了微反应器中的单相催化反应。讨论了可能影响催化反应的几个因素，包括压降、催化剂颗粒的大小和通道结构。最后，可以得出一些重要的结论。压降的变化对反应有影响。例如，C3H6压降为8[公式：见正文]atm时转化率为62.88%，C3H6压降为11[公式：见正文]atm时转化率为61.78%。改变粒子半径对反应的影响不明显。在进入反应域之前加强物质的混合有利于催化反应。在微反应器中不同位置的催化剂颗粒中存在不同的物质浓度。但从催化剂颗粒的表面到内部，物质浓度有明显的变化规律。
