摘要
在微型管式反应器中,采用高效的Pd/Al2O3催化剂,在388～418 K的温度范围,1∶1～3∶1的CO与MN比,50～150 mL/min的原料气流速条件下进行了CO与亚硝酸甲酯催化偶联合成草酸二甲酯的本征动力学实验;通过对反应机理的推导,动力学模型的筛选及优化,得出CO偶联合成草酸二甲酯的本征动力学模型。结果表明:CO与亚硝酸甲酯催化偶联合成草酸二甲酯是以表面羰化反应为控制步骤。
In this paper, the intrinsic kinetic experiment had been done in a mini tube reactor with high-effective Pd/Al2O3 catalyst. The experiment of intrinsic kinetic research on vapor-phase catalytic coupling of CO and methyl nitrite to DMO was under the follow conditions： temperature was 388-418 K, CO/MN ratio was 1 ： 1~3 ： 1 material, space velocity was 50-150 mL/min. Through derivation of the reaction mechanism, well selection and optimization of dynamics models, the intrinsic kinetic model of the vapor-phase coupling of CO and methyl nitrite was obtained, the results showed that the surface carbonyl reaction was the control step of the coupling synthesis of CO and methyl nitrite.
