Hydrogenation Catalyst, and Preparation Method Therefor and Use Thereof

A method for preparing a hydrogenation catalyst, the hydrogenation catalyst comprising a carrier, an active component and an auxiliary agent;

• wherein the carrier has a directional honeycomb pore structure, an average pore size of the honeycomb pore is 5 to 20 μm, the active component and the auxiliary agent are loaded on an outer surface of the carrier and an inner wall of the honeycomb pore, and a catalytic layer is formed on the outer surface of the carrier and the inner wall of the honeycomb pore, and a thickness of the catalytic layer is 30 to 100 nm, the method comprising following steps:
• 1) mixing a carrier raw material with a solvent, followed by ultrasonication, then adding a binder, followed by ball milling to obtain a carrier slurry;
• 2) freezing and drying the carrier slurry to obtain a carrier blank;
• 3) calcining the carrier blank to obtain a catalyst carrier;
• 4) adding a precursor impregnation liquid of the active component and the auxiliary agent to a surface of the catalyst carrier, and then treating the catalyst carrier under a vacuum condition, followed by drying and roasting to obtain the hydrogenation catalyst.
