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.

以Pd基催化剂为催化剂，考察了二甲醚水蒸气重整制氢反应。掺入Al_2O_3的共沉淀法制备的PdZn合金对水蒸气重整反应具有较高的催化活性、选择性和稳定性。还考察了PdZn合金催化剂选择性氧化脱除重整气中一氧化碳的效果。添加Cs、Rb等碱金属化合物可显著提高PdZn合金催化剂的活性。结果表明，这些添加剂对CO氧化有促进作用，但对有害的H2氧化有抑制作用。
