ZnO Nanowire-supported Ag Catalyst for Methanol Steam Reforming

Alternative energy sources, such as various fuel cell technologies, have attracted intense attention due to their high efficiency and low emissions of pollutants. Methanol, with its high hydrogen/carbon ratio, low sulfur content and the absence of carbon–carbon bonds, has been identified as a highly suitable source for onboard production of hydrogen [1]. Among several reactions for converting m...

Pd/Ga2O3 methanol steam reforming catalysts: Part II: Catalytic selectivity

Structure, morphology and composition of two Pd/Ga2O3 methanol steam reforming catalysts were correlated with the associated activity and selectivity changes in the methanol steam reforming reaction and linked to studies on pure Ga2O3 supports. For both systems, that are, a Pd/Ga2O3 thin film model catalyst and a powder-supported Pd catalyst, we identified a temperature range in which the reduc...

Progress in enzymatic membrane reactors – a review

The enzymatic membrane reactor (EMR) consists on a coupling of a membrane separation process with an enzymatic reaction. The selective membrane aims to separate the biocatalyst from the reaction products. The main objective of EMR is to ensure the complete rejection of the enzyme in order to maintain the full activity inside the reacting volume. Depending on the case, enzyme molecules may be fr...

Effects of Catalysts and Membranes on the Performance of Membrane Reactors in Steam Reforming of Ethanol at Moderate Temperature

Steam reforming of ethanol in the membrane reactor using the Pd77Ag23 membrane was evaluated in Ni/CeO2 and Co/CeO2 at atmospheric pressure. At 673 K, the H2 yield in the Pd77Ag23 membrane reactor over Co/CeO2 was found to be higher than that over Ni/CeO2, although the H2 yield over Ni/CeO2 exceeded that over Co/CeO2 at 773 K. This difference was owing to their reaction mechanism. At 773 K, the...
