摘要: A process for the preparation of copper-iron-aluminum hydrogenation catalysts comprises step of: dissolving a cupric salt, ferrous salt and an aluminum in water urea resulting aqueous solution such amount that mole number is at least 0.7 time as large sum equivalents metal ions, heating mixed solution, further continuing until pH liquid 4.6 to 7.5, adding alkali reaction elevate 9.5 11.5, conducting then separating, water-washing, drying calcining formed precipitate.
