Abstract
The present invention discloses a selective hydrogenation catalyst and a preparation method and an application thereof, belonging to the technical field of catalysts. The selective hydrogenation catalyst comprises an active component and a carrier for supporting the active component, wherein the active component is a transition metal particle, the carrier is modified by a flexible chain ligand in advance, one end of the flexible chain ligand is uniformly distributed on the surface of the carrier, and the other end of the flexible chain ligand is coordinated on a transition metal. When the catalyst is used for catalytic hydrogenation reaction of dehydrolinalool or 2-methyl-3-butyn-2-ol, the stability is good, the catalyst still has high selectivity after being used for a long time, and the quality of a hydrogenation product can be guaranteed.
