Description

technical field

[0001] The invention relates to the technical field of catalyst preparation, in particular to the technical field of vinyl acetylene hydrogenation catalyst preparation. Specifically, the present invention relates to a vinyl acetylene hydrogenation catalyst and its preparation method and use. More specifically, the present invention provides a vinyl acetylene hydrogenation catalyst, a method for preparing a vinyl acetylene hydrogenation catalyst, a method for preparing butadiene, and a butadiene product. Background technique

[0002] Butadiene is an important petrochemical basic organic raw material and high polymer monomer. Its position in petrochemical olefin raw materials is second only to ethylene and propylene, and it has a wide range of uses. It can not only be used to produce synthetic butadiene rubber (BR), styrene-butadiene rubber (SBR), nitrile rubber, styrene-butadiene-styrene elastomer (SBS), acrylonitrile-butadiene-styrene ( ABS) resin and other...
