| Research Abstract |
Hydrogen production by steam reforming of dimethyl ether was investigated with Pd-based catalysts. PdZn alloy prepared by co-precipitation method mixed with Al_2O_3 exhibits high catalytic activity, selectivity and stability for the steam reforming reaction. Removal of carbon monoxide in the reformed gas by selective oxidation was also examined with PdZn alloy catalyst. The activity of the PdZn alloy catalyst can be significantly improved by the addition of alkali metal compounds, such as Cs and Rb. These additives were shown to enhance the CO oxidation but suppress the undesired H_2 oxidation.
