| Abstract: | The methanol steam reforming was performed using a micro fixed-bed reactor at atmospheric pressure, with CuZnZrAlO as the catalyst, and the effects of pseudo residence time W/FA0 on the conversions of methanol to outlet CO and CO2 were investigated at 503 - 543 K. By carrying out the direct methanol reforming and the methanol decomposition in parallel, a kinetic model suitable for the parallel reaction route was then established on the condition that the effects of internal and external diffusing were eliminated, with the outlet CO and CO2 as the two key indexes. Moreover, the corresponding model parameters were determined by means of the least square method. The F-test demonstrates that the proposed kinetic model is suitable for the simulation and design of the reactor for methanol steam reforming. |
