hydrogen can be produced for fuel cell applications by using methanol steam reforming reaction. in this article, a method was developed for regeneration of accelerated deactivated methanol-steam-reforming catalyst. successive deactivation–regeneration cycles were studied in a 250 hours test for the first time including 6 regeneration cycles. it is shown that regeneration of the catalyst in dilu...

The activation and catalytic performance of two representative Zr-containing intermetallic systems, namely Cu-Zr and Pd-Zr, have been comparatively studied operando using methanol steam reforming (MSR) as test reaction. Using an inverse surface science and bulk model catalyst approach, we monitored the transition of the initial metal/intermetallic compound structures into the eventual active an...

Abnormal growth of population and development enormously increases energy demand. In present scenario utilization of fossils fuels to meet this demand is not enough and also leads to pollution, global warming, climate change as well as natural disaster. Therefore, hydrogen as energy carrier is a major option on these prospects as it is non-polluting and renewable. The renewable hydrogen energy ...

Fuel cell powered electric cars using on-board methanol or hydrocarbon reforming to produce a hydrogenrich gas represent a low-emissions alternative to gasoline internal combustion engines (ICE) with well-towheel efficiencies of 17 %. For the overall methanol process, a simplified model of the reaction network consisting of the total oxidation of methanol, the reverse water-gas shift reaction, ...

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...

High-power-density alcohol fuel cells can relieve many of the daunting challenges facing a hydrogen energy economy. Here, such fuel cells are achieved using CsH2PO4 as the electrolyte and integrating into the anode chamber a Cu-ZnO/Al2O3 methanol steam-reforming catalyst. The temperature of operation, 250°C, is matched both to the optimal value for fuel cell power output and for reforming. Peak...

Dielectric Barrier Discharges (DBD) operated at atmospheric pressure and working at reduced temperatures (T < 115 degrees C) and a copper-manganese oxide catalyst are combined for the direct decomposition and the steam reforming of methanol (SRM) for hydrogen production and for the preferential oxidation of CO (CO-PROX).

A short time (3-10 min) of microwave irradiation on the CuO/ZnO/Al2O3 oxide precursor can result in a unique tailored microstructural modification on the catalyst, leading to a significantly enhanced performance for H2 production from steam reforming of methanol.
