Beschreibung
Zusammenfassung:	The invention relates to a dimethyl ether vapor reformed hydrogen catalyst and a method for preparing the same. The composition general formula of the catalyst is Cu/M/gamma-Al2O3, wherein M represents one or more of metals or metal oxides of nickel, manganese, lanthanum, zinc, zirconium and yttrium, and the mol ratios of the components of the catalyst are: 1 of Cu, 0.2 to 2 of M and 0.8 to 17 ofgamma-Al2O3. The catalyst is one-time prepared by a deposition-sedimentation method and has the advantages of simple preparation process, low cost, high catalytic activity, good stability, and the like.
