摘要: Abstract Studies of promotional effects chromia on structure and properties skeletal copper catalysts for methanol synthesis have been carried out. Catalysts were prepared by selective dissolution aluminum from CuAl 2 alloy and, at the same time, precipitation surface residual using a caustic solution containing sodium chromate. Deposition was found to greatly influence pore specific area, resulting in relative decrease diameter remarkable enhancement while total volume maintained constant. Significant improvements activity selectivity achieved adding small amounts (about 3.5 wt.%) copper. However, higher loadings be unfavorable reactions. The results obtained this study suggest that acts as structural promoter provides high area synthesis. chromia-promoted produced method are likely applications organic hydrogenation reactions water gas shift reaction.
