Abstract:
1. A catalyst, capable of being used as a catalyst in producing aromatic amines, having the following composition: wherein M is Ni and/or Co; X is at least one element selected from the group consisting of Li, Na, K, Rb, Cs, Be, Ca, Ba, Ti, Cu, Cr, Zn, Mn, Mg, Fe, Ga, Ge, Nb, Ru, Rh, Pd, Ir, Pt, Bi, Al, Si, In, Sr, Ce and Mo; and a, b, c and d respectively are atomic ratios wherein a is 0.03 to 1.0, b is 0 to 1.0, c is 0.05 to 0.6, and d is a number of oxygen atoms bonded to Zr and to X when X is an oxide, with zirconia being included as a carrier component, wherein the catalyst is prepared by drying, calcining and reducing a precipitate produced by adding an aqueous solution containing a soluble salt of the metal catalyst component and a soluble salt of the carrier component to an aqueous alkali solution, or a mixture of a precipitate produced by adding an aqueous solution containing a soluble salt of the metal catalyst component to an aqueous alkali solution, and a precipitate produced by adding a soluble salt of the carrier component to an aqueous alkali solution, and then forming the dried, calcined and reduced precipitate into the catalyst.
