Stability tests of CuZnAl catalysts in dimethyl adipate hydrogenolysis under continuous-flow conditions
Original language description
Dimethyl adipate hydrogenolysis is one of the industrial processes restricted by environmental regulations because it uses a chromium-containing catalyst . However, chromium has an important function as a structural promoter and stabilizer for copper particles that are active sites for hydrogenolysis1. We suppose that less the harmful CuZnAl has a similar stability and could be used instead of CuCr2. For this purpose, we synthesized a CuZnAl catalyst with Cu/Zn ratio of 1.5 and Al/(Cu+Zn) ratio of 0.2 by a co-precipitation method and calcined it at 350 °C. Then, the catalyst was characterized by basic characterization methods, reduced in situ at 220 °C and tested in dimethyl adipate hydrogenolysis in a fixed-bed reactor under continuous-flow conditions. Several catalytic tests were carried out to investigate the activity, selectivity and stability of the catalyst. Besides the monitoring of structural changes with time-on-stream, the change in the conversion of dimethyl adipate with time was also evaluated.
