| titleOfInvention | A kind of bimetallic component isophthalonitrile hydrogenation catalyst and its preparation and application |
| abstract | The invention discloses a preparation method and application of a bimetallic component isophthalonitrile hydrogenation catalyst. The preparation method includes preparing the silica gel carrier precursor by co-precipitation method, adding active metal solution, auxiliary agent solution and alkaline precipitating agent. The target catalyst is obtained through washing, drying, granulation, roasting and reduction. Compared with the catalyst prepared in the prior art, the catalyst prepared by the method of the invention has more stable activity and yield of m-xylylenediamine in the reaction of preparing m-xylylenediamine through continuous hydrogenation of a fixed bed. The invention solves the problems of easy catalyst deactivation and low product selectivity in the prior art, and has good industrial application prospect. |
