AbstractIn the present study, a series of Ir-based catalysts, supported on Al2O3, ZrO2, CeO2, and CexZr1-xO2, are investigated for the production of hydrogen by the high temperature steam reforming of methanol (SRM). Results show that CeO2 and CexZr1-xO2 can promote the CO water gas shift (WGS) reaction, which is involved in the SRM network. Ir/CeO2 exhibits a better initial methanol conversion and its stability can be enhanced by the addition of ZrO2 to CeO2. The TPR and XRD characterization of the CeO2-ZrO2 mixed oxides shows that Ce0.5Zr0.5O2 is the optimum support in maintaining catalyst activity, as well as stability. The addition of the precious metal Pt to Ir/Ce0.5Zr0.5O2 demonstrates a synergistic effect and can obviously increase the selectivity of H-2. In the meantime, the CO content in the reformate products decreases from 9 mol-% to 6 mol-%. Under the conditions of H2O/ CH3OH=1.5 (molar ratio), LHSV=2.5 h(-1), and a reaction temperature of 400 degrees C, a 92% methanol conversion is obtained during a 200 hour test on a 0.3%Ir-0.3%Pt/Ce0.5Zr0.5O2 catalyst and the stability is better than that of a commercial copper-based catalyst.
