摘要: The kinetics of low-pressure methanol synthesis, starting from CO, CO2 and hydrogen over a commercial CuZnAl catalyst, were studied in spinning basket reactor at p = 15–50 bar T 210–245°C. results show that can be formed both CO CO2. Besides these two reactions the water-gas-shift reaction takes place. Based on three dual-site adsorption mechanism, 48 kinetic rate models are derived. Hydrogen is believed to adsorb dissociatively. experimental support this assumption. χ2-statistics consistency tests final model selected. This gives significantly better agreement with than taken recent literature.
