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