Abstract. The effect of oxygen mobility on the bio-ethanol steam reforming of ZrO2- and CeO2-supported cobalt catalysts was investigated. The supported catalysts were prepared by incipient wetness impregnation (IWI) and characterized through N2 physisorption, X-ray photoelectron spectroscopy, temperature programmed oxidation, laser Raman spectroscopy, diffuse reflectance infrared Fourier tr…
Abstract. Zr-containing CuO/ZnO catalysts are examined for their use in the reaction of methanol with water to produce hydrogen. Catalyst samples with varying compositions were prepared by means of a coprecipitation method, and the effect of different pretreatment conditions was examined. Activity testing shows that the catalysts do not require prereduction to obtain good activity for the stea…
Abstract. Propane steam reforming was studied over Ni–Al2O3 catalysts that were prepared by a conventional impregnation (IM) method and a one-step sol–gel (SG) technique. Both Ni–Al2O3 catalysts showed similar initial activity. However, IM-Ni–Al2O3 deactivated severely with time-on-stream of propane steam reforming. The catalyst prepared using a SG technique demonstrated stable cata…
