  • Palladium-based supported hydrogenation catalyst, and preparation method and application thereof
    Patent number: 10800717
    Abstract: The present invention relates to a palladium-based supported hydrogenation catalyst and a preparation method and application thereof. The catalyst is prepared by the following method: impregnating an Al2O3-containing carrier with an organic solution containing a bipyridine derivative having hydroxy group, optionally drying followed by impregnating with a mixed solution containing the main active component palladium ions and the auxiliary active component Mn+ ions, where M is one selected from Ag, Au, Ni, Pb and Cu; and then optionally drying, and calcining to obtain the catalyst. The preparation method provided by the present invention allows Pd atoms and M atoms to be highly uniformly dispersed on the carrier, which overcomes the adverse impact of the surface tension of the impregnation solution and the solvation effect on the dispersibility of active components.
