Supported metal catalysts in the form of spherical particles are produced by adding a solution or suspension containing a polysaccharide and metal compound(s) of iron, cobalt, nickel, copper or zinc to a metal salt solution and then drying and reducing the separated product. A method for the production of formed spherical supported metal catalysts (I) with a metal content of 10-70 wt.% involves: (a) treating a solution of metal salt (II) with a solution or suspension containing a mixture of a polysaccharide and metal compound(s) (III) in a liquid medium; (b) separating the resulting spherical catalyst particles from the solution after 1-180 minutes; (c) drying at 80-150 degrees C; and (d) reducing at 150-600 degrees C. Compounds (III) comprise oxides, hydroxides, basic carbonates, hydrogen-carbonates, silicates, zirconates, aluminates, titanates, chromites and aluminosilicates of iron, cobalt, nickel, copper or zinc. (a) Independent claims are also included for (1) catalysts (I) as described above (2) a method for the hydrogenation of aromatic compounds in presence of (I). |
