钼铁催化剂上甲缩醛空气氧化制浓甲醛的宏观动力学

STUDY ON MACROKINETICS OF OXIDATION OF METHYLAL TO FORMALDEHYDE OVER Mo Fe CATALYST

在５４３～６３１Ｋ温度范围内，使用磁驱动内循环无梯度反应器，研究了在工业粒度的钼铁催化剂上甲缩醛空气氧化制浓甲醛的宏观动力学。确立了甲缩醛催化氧化反应的简化网络，由实验数据回归得到了宏观动力学方程。用此方程，采用固定床拟均相模型进行模拟计算，所得结果与单管试验结果吻合较好。

Study on macrokinetics of oxidation of methylal to formaldehyde over a Mo Fe catalyst was performed in a magnetic driving, internal recycling gradientless reactor within 543￣631 K under normal pressure. The simplified reaction network was set. Based on the experimental data, the macrokinetics model was established. Combining the macrokinetics model with pseudo homogeneous packed reactor model, simulating calculation was made. The results agree well with the experimental results of the single tube reactor, and this means that the macrokinetics model is suitable for the reactor scale up.
