Abstract (EN):
A kinetic study within the low-temperature methanol steam reforming
(MSR) reaction was performed over a novel CuZrDyAl catalyst. The physicochemical and catalytic properties of the CuZrDyAl catalyst were compared with
those of a conventional CuO/ZnO/Al2O3 (G66 MR, Su¨d-Chemie) sample. The inhouse catalyst displays better performance than the reference G66 MR sample in
terms of methanol conversion and selectivity. The parameters of a simple powerlaw equation and two mechanistic kinetic models were determined minimizing the
residual sum of squares; the best fitting with the experimental data were obtained
when using Model 3, based on the reported work from Peppley et al. (Appl Catal A
179:31–49, 1999) for the commercial CuO/ZnO/Al2O3. Noteworthy is the small
number of MSR kinetic studies at 170–200 C temperature range.
