Low-temperature methanol steam reforming kinetics over a novel CuZrDyAl catalyst

Abstract

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 withthose of a conventional CuO/ZnO/Al2O3 (G66 MR, Sušd-Chemie) sample. The inhouse catalyst displays better performance than the reference G66 MR sample interms of methanol conversion and selectivity. The parameters of a simple powerlaw equation and two mechanistic kinetic models were determined minimizing theresidual sum of squares; the best fitting with the experimental data were obtainedwhen using Model 3, based on the reported work from Peppley et al. (Appl Catal A179:31-49, 1999) for the commercial CuO/ZnO/Al2O3. Noteworthy is the smallnumber of MSR kinetic studies at 170-200 C temperature range.
