摘要: The kinetics of the steam reforming methanol (SRM) was studied in a packed bed reactor over Mn-promoted Cu/Al2O3 catalyst at atmospheric pressure, temperature range 170 to 250 oC, and weight time (W/FA0) 0.38 2.40 g-cat.h.mol-1 CH3OH. A LHHW type mechanism that assumes dissociative adsorption on two distinct active sites as rate-controlling step found satisfactorily describe SRM reaction with activation energies 77.3 64.5 kJ mol-1 low high temperature, respectively. It also there were no mass or heat transfer limitations under experimental conditions used this study. model developed, validated, predict conversion, concentration profiles. axial dispersion had effect distribution but more pronounced conversion.
