Nickel-silver series hydrogenation catalysts and preparation method thereof

The invention relates to a nickel-silver series catalysts and a preparation method thereof, in particular related to a preparation method of nickel-silver series hydrogenation catalysts using nickel-containing alumina as a carrier. The nickel-silver hydrogenation catalyst contains active components of nickel and copper, the nickel-containing alumina is used as the carrier, a precursor of the nickel-containing alumina carrier is nickel-containing pseudo-boehmite, and the preparation process of the nickel-containing pseudo-boehmite includes acid-base neutralization and gelling processes; a specific carrier is used in the catalysts provided by the invention, and the specific carrier has the advantages that nickel and the pseudo-boehmite can be organically combined, so that the active component nickel is effectively dispersed in the pspseudo-boehmite, and the nickel-containing alumina carrier swith a specific crystal form is formed; the method has a good regulation effect on a pore structure and acidity of the ca
