Abstract

original image

Eine einfache thermische Behandlung erhöht die Aktivität und Haltbarkeit von CuFe2O4-Al2O3-Katalysatoren beim Reformieren von Dimethylether zur Wasserstofferzeugung merklich. Am wirkungsvollsten ist eine Behandlung zwischen 700 und 800 °C. Die aktive Phase CuFe1.5Al0.5O4, die in einer Festkörperreaktion zwischen CuFe2O4 und Al2O3 entsteht, und die Originalphase CuFe2O4 tragen synergistisch zur Verbesserung bei.
