| titleOfInvention | A kind of copper-based hydrogenation catalyst, its preparation method and application |
| abstract | The invention belongs to the technical field of catalysts, and in particular relates to a copper-based hydrogenation catalyst, a preparation method and application thereof. The preparation method of the copper-based hydrogenation catalyst includes the following steps: 1) dissolving soluble copper salt, soluble zinc salt and auxiliary salt compounds into deionized water in turn to form a mixed solution; Add the aqueous solution of silicon dioxide powder and precipitant to the mixed solution successively, stir evenly and precipitate; 3) filter and wash the precipitate described in step 2) to obtain a catalyst precursor; 4) mix the precipitation in step 3) The catalyst precursor is pretreated to obtain a copper-based hydrogenation catalyst. In addition, the present invention also provides a copper-based hydrogenation catalyst prepared by the above method and its application. The copper-based hydrogenation catalyst of the present invention is applied in the production of rubber antioxidants, which can obviously improve the conversion rate of raw materials and the yield of target products, and reduce the proportion of ash in the products. |
