A process for preparing an aromatic amine by reacting a corresponding aromatic alcohol with an aminating agent selected from the group consisting of ammonia, primary amines and secondary amines, in the presence of hydrogen and a catalyst molding, at a temperature of from 60-300°. The catalyst molding comprises Zr, Pd and Pt and has an annular tablet form with an external diameter in the range from 2-6 mm, a height in the range from 1-4 mm and an internal diameter of from 1-5 mm or a topologically equivalent form with the same volume. Catalyst moldings comprising Zr, Pd and Pt are also provided. The catalyst molding has an annular tablet form with an external diameter in the range from 3-6 mm, a height in the range from 1-4 mm and an internal diameter of from 2-5 mm or a topologically equivalent form.
