As catalysts for producing aromatic amines by hydrogenating aromatic
nitrites, there are disclosed (1) the catalyst comprising a metal
catalyst component comprising Ni and/or Co and a specific amount of
zirconia as a carrier component, which is prepared by drying, calcining
and forming a precipitate produced by adding an aqueous solution
containing soluble salts of the metal catalyst component and the carrier
component to an aqueous alkali solution; and (2) the catalyst comprising
the metal catalyst component and the carrier component, which is prepared
by filtering a precipitate produced by adding an aqueous solution
containing soluble salts of the metal catalyst component and the carrier
component to an aqueous alkali solution; forming the precipitate without
drying to obtain a formed product; and subjecting the formed product to
drying and then calcining. These catalysts are free from breaking owing
to rapid generation of methane and evaporation of liquid ammonia by
hydrogenolysis of high boiling by-products of the hydrogenation when
reactivated after deactivation of the catalyst, which allows the
long-term use of the catalysts.
