| titleOfInvention | Skeletal cobalt catalyst and preparation method and application thereof |
| abstract | The invention belongs to the technical field of catalyst preparation, and particularly relates to a skeletal cobalt catalyst, and a preparation method and application thereof; the preparation method comprises the following steps: (1) mixing cobalt, aluminum and a metal auxiliary agent in an inert gas environment, and heating to melt the mixture to obtain an alloy liquid; (2) contacting the alloy liquid with the macroporous inert ceramic balls, and pressing the alloy liquid into the pore channels of the macroporous inert ceramic balls, wherein the macroporous inert ceramic balls comprise pore channels with the pore diameter of 300-1000 um; (3) cooling the inert ceramic balls pressed into the alloy liquid step by step to-10-5 ℃; shaping the cooled inert ceramic ball to prepare a catalyst precursor; (4) and carrying out in-situ activation on the obtained catalyst precursor to prepare the skeletal cobalt catalyst. The invention also relates to skeletal cobalt catalyst products and uses thereof. The preparation method of the catalyst can improve the utilization rate of the active metal Co and reduce the cost, and the obtained catalyst has stronger activity and better selectivity. |
