Mikrostrukturen für die katalytische Wasserstofferzeugung aus Ethanol

Hydrogen for fuel cell applications has been generated by catalytic steam reforming of ethanol in microstructures. The influence of reaction temperature, contact time and molar ratio steam to carbon (S/C) on the reaction has been investigated. The Co/ZnO catalyst coated on the microstructure showed high activity and selectivity. The hydrogen yield obtained was up to 5.2 mol mol^–1 ethanol. Ethanol has been completely converted at short contact time (W/F 25 g min mol^–1) and 600 °C at S/C ratio between 4.9 and 6.5.
