本文研究丙烯在Gd_2O_3·3MoO_3上的氧化反应动力学,提出了一种反应历程。即在较低温度下,反应控制步骤是吸附丙烯和吸附的分子氧之间的反应,但在较高温度下,反应遵从Rideal反应历程。这样的历程对于生成丙烯醛、二氧化碳、乙醛的不同动力学行为得到统一的解释。 In this paper, the oxidation kinetics of propylene on Gd_2O_3 · 3MoO_3 was studied, and a reaction process was proposed. That is, at lower temperatures, the reaction control step is the reaction between the adsorbed propylene and the adsorbed molecular oxygen, but at higher temperatures the reaction follows the Rideal reaction. Such a process for the generation of acrolein, carbon dioxide, acetaldehyde different kinetic behavior of a unified explanation.
