Verfahren und Vorrichtung zur Gewinnung eines wasserstoffreichen, kohlenmonoxidarmen Gases

摘要

Gas high in H2 and low in CO is obtained by subjecting the gas obtained by reforming methanol using a Cu/ZrO2 or Cu/ZnO/ZrO2 catalyst to selective methanisation using a catalyst/carrier containing TiO2, Al2O3, Ru and RuOx and/or selective oxidation using a catalyst material containing Pt and TiO2. The methanisation Ru/RuOx and a TiO2 composition of 75% rutile and 25% anatase. Also claimed is an apparatus for obtaining such a gas consisting of a methanol reforming reactor and a CO converter for carrying out the above process.
