Computation of effectiveness factor for methanol steam reforming over Cu/ZnO/Al2O3 catalyst pellet

ZnO Nanowire-supported Ag Catalyst for Methanol Steam Reforming

Alternative energy sources, such as various fuel cell technologies, have attracted intense attention due to their high efficiency and low emissions of pollutants. Methanol, with its high hydrogen/carbon ratio, low sulfur content and the absence of carbon–carbon bonds, has been identified as a highly suitable source for onboard production of hydrogen [1]. Among several reactions for converting m...

Methanol steam reforming; Effects of various metal oxides on the properties of a Cu-based catalyst

Ternary Cu/ZnO/metal oxide catalysts are prepared through the co-precipitation method under strict control of parameters like pH, calcination conditions, and precipitation temperature in a systematic manner. The metal oxides applied in this study consist of Al2O3, ZrO2, La2O3 and Ce2O3. The distinction of this work in comparison with similar research is a comprehensive investigatation of the ca...

Performance Evaluation of Cu-SiO2 Aerogel Catalyst in Methanol Steam Reforming

Methanol Steam Reforming Catalyzing over Cu/Zn/Fe Mixed Oxide Catalysts

Methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. To accomplish higher methanol conversion and lower CO production, the reaction was catalyzed by CuZnFe mixed oxides. Various ratios of Fe and Cu/Zn were coprecipitated in differential method to optimize the CuZnFe structure. The sample containing 45Cu50Zn5Fe (Wt. %) revealed its m...

In situ Studies of Alloy Formation on a Pd/Ga2O3 Methanol Steam Reforming Catalyst

Methanol steam reforming is a promising reaction in terms of hydrogen production for use in PEM fuel cells. Catalyst research has focused mainly on Cu/ZnO formulations, because of their superior selectivity to CO2 and H2. The common byproduct CO is problematic due to its poisoning effect on the anode of a downstream fuel cell. Some years ago it was shown that palladium supported on certain redu...
