| titleOfInvention | Copper-based catalyst for dimethyl oxalate hydrogenation and preparation method and application thereof |
| abstract | The invention discloses a copper-based catalyst for dimethyl oxalate hydrogenation and a preparation method and application thereof, wherein a deposition-precipitation method is used for loading soluble copper salt on mesoporous silica nanospheres with central radial pore canals; the copper content in the prepared catalyst is 10-45% of the total weight of the catalyst, and the monovalent copper content is 10-60 mol% of the total active copper mol number; specific surface area of catalyst>500m 2 G, pore volume>1.0ml/g, and the average mesoporous size is 2.8-10 nm. The catalyst preparation method can regulate and control the size and the dispersity of copper species in the final catalyst, improve the synergistic effect of monovalent copper and zero-valent copper and obtain the high-dispersity supported nano copper metal catalyst; the catalyst is used for the reaction of synthesizing the glycol by hydrogenating the dimethyl oxalate, wherein the conversion rate of the dimethyl oxalate>99% ethylene glycol selectivity>96 percent, the catalyst has simple preparation process and low cost, and is beneficial to realizing industrial application. |
