Ester Hydrogenolysis over Cu/ZnO/Al2O3 catalysts : Effect of Cu/ZnO ratio |
| 초록 |
Hydrogenolysis of ester was studied over Cu/ZnO/Al2O3 catalysts. The kinetic data were measured by changing H2 partial pressure, ester partial pressure, and reaction temperature on the basis of the empirical power-law equation. Cu/ZnO/Al2O3 catalysts were prepared by a coprecipitation technique, where the Cu/Zn ratio and the support were changed. The catalysts were characterized using XRD, H2-TPD, O2-TPD, and N2O chemisorption. Among the supports tested in this study, Al2O3 exhibited the highest ester yield. Furthermore, it was found that the Cu/ZnO/Al2O3 catalyst with the Cu/Zn ratio of 5/1 showed the highest activity in ester hydrogenolysis due to the largest surface area of active Cu species (The authors would like to acknowlege funding from the SK Energy Corporation). |
