Hydrogen from steam reforming of ethanol. characterization and performance of copper-nickel supported catalysts

The effect of the copper loading and calcination temperature on the structure and performance of Cu/Ni|K|γ-Al2O3 catalysts is examined. TPR, XRD and N2O chemisorption techniques are employed. Activity and selectivity measurements are carried out considering steam reforming of ethanol as the test rea...
