摘要
以液体石蜡为液相介质 ,在富 CO合成气条件下研究了 C30 2铜基催化剂上 CO、CO2 加氢合成甲醇的宏观反应动力学 ,得到了相应的动力学模型 ,通过对模型进行比较 ,认为在 CO浓度较高的情况下 ,幂函数模型优于 Langmuir- Hinshelwood模型。实验结果表明 ,催化剂和液相介质在富 CO合成气条件下表现出良好的适应性。
The global reaction kinetics of three phase methanol synthesis, starting from carbon mon oxide, carbon dioxide and hydrogen over a commercial copper based C302 catalyst suspended in paraffin oil as the liquid medium, was studied at the pressure ranging from 2.0MPa to 5.0MPa, and the temperature ranging from 210°C to 225°C in a mechanically agitated slurry reactor. Two different kinetic models, a power law type and a L H type, were selected. The experimental results showed that the power law type model developed from the rate data for CO rich synthesis gas gives a better agreement with the experimental data than the L H model. Besides, it turns out that the catalyst and the liquid medium were fitted for methanol synthesis using CO rich synthesis gas. The experimental results provided the basis of analysis for further development of novel technology of three phase methanol synthesis.
