摘要: The present disclosure provides a hydrogenation catalyst, the preparation process thereof and the application thereof in the production of 1,4-butanediol by hydrogenating dialkyl maleate and/or dialkyl succinate. The catalyst comprises Cu—Al-A-B—O, wherein A comprises at least one of Zn, Mo and W, B comprises at least one of Ba, Mn, Mg, Ti, Ce and Zr. In the process for preparing said hydrogenation catalyst, a part of Cu and A are precipitated first and the rest of Cu, Al and B are precipitated successively.
