      Abstract: The intrinsic reaction kinetics of methanol synthesis, starting from carbon monoxide, carbon dioxide and hydrogen over a commercial C302 type copper based catalyst, was studied. To make the intrinsic kinetics be used for the three phase methanol synthesis process, the feed gases with higher contents of CO(8%~26%) have been used, but the temperature and pressure of reaction were still within the range of actual industrial process of gas phase methanol synthesis. The Langmuir Hinshelwood type dual rate equations have been selected to depict the intrinsic reaction rates. The calculated results of these kinetic models are in very good agreement with the experimental results. The intrinsic kinetic models were examined by the method of mathematics statistics and proved to be suitable. They can be used for process development and engineering design of methanol synthesis in three phase as well as in gas solid phase.
