Copper-based catalysts in dimethyl adipate hydrogenolysis

Popis výsledku v původním jazyce

Copper- and zinc-based catalysts are commonly used in methanol synthesis, water-gas shift reaction or hydrogenation of various oxygenates to produce valuable products. Nonetheless, their importance could be even greater. Due to EU environmental directives, the copper- and chromium-based catalysts (so called Adkins catalysts) for ester hydrogenolysis are being eliminated, and thus CuZn-based catalysts could be a potential alternative. In these catalysts, copper possesses the catalytic activity for hydrogenation of C=O bond, while zinc promotes the stability. The question is if the copper particles stabilization only by zinc is sufficient. For this purpose, CuZn and CuZnAl catalysts were prepared by a conventional co-precipitation method as a common method of the catalyst synthesis to compare their stability and catalytic activity. As-prepared catalysts were calcined in air, in situ reduced at 220°C and tested in ester hydrogenolysis. Hydrogenolysis of dimethyl adipate to hexane-1,6-diol was chosen as a model reaction. All catalysts were characterized in each single step to determine their physico-chemical properties such as phase composition, specific surface area or reducibility. Namely, AAS, XRD, BET, TGA-MS, NH3-TPD and H2-TPR methods were used.
