Hydrogenation of Dimethyl Succinate and Ethyl Lactate over Copper-Silica Nanocomposite Catalysts |
| 초록 |
Copper-silica nanocomposite catalysts have been designed to investigate vapor-phase hydrogenation of bio-based dimethyl succinate and ethyl lactate at elevated pressures. These catalysts have been prepared by precipitation–deposition. The conversion of ethyl lactate over the catalyst by precipitation–deposition method was about two times higher than that by sol–gel and wet impregnation methods. Copper loading could be increased up to 80 wt% on silica while maintaining a Cu particle size smaller than 15 nm by the precipitation–deposition method, where the highest specific Cu surface area was obtained. In the hydrogenation of dimethyl succinate, the smaller Cu particles size was more advantageous to higher conversion and higher tetrahydrofuran (THF) selectivity, while the larger Cu particle size was more advantageous to higher GBL selectivity. |
