Abstract	ZnO and Cr$_{2}$O$_{3}$ promoted skeletal copper catalysts have been prepared by leaching CuAl$_{2}$ alloy particles in aqueous sodium hydroxide containing various concentrations of sodium zincate (Na$_{2}$Zn(OH)$_{4}$) (0–0.62 M), of sodium chromite (NaCrO$_{2}$) (0–0.1 M) or of a mixture of sodium zincate (0.005 M) and sodium chromite (0.02 M). Both sodium zincate and sodium chromite in the caustic solution were found to affect the leaching process. The presence of sodium zincate retarded the leaching rate and enhanced the specific surface area of the catalyst but did not protect copper rearrangement on extended leaching. On the other hand, sodium chromite in the leachant did not influence the leaching rate but the leached catalyst was more stable with the structure and surface area of the skeletal copper being maintained. The activities of ZnO and Cr$_{2}$O$_{3}$ promoted skeletal copper catalysts for the reactions of methanol synthesis, water gas shift and methanol steam reforming were determined separately. The results indicated that deposition of both ZnO and Cr$_{2}$O$_{3}$ on skeletal copper catalysts significantly improved the activities for these reactions. Chromia is found to act mainly as a structural promoter.
