    • PCT No. PCT/EP87/00115 Sec. 371 Date Oct. 15, 1987 Sec. 102(e) Date Oct. 15, 1987 PCT Filed Feb. 26, 1987 PCT Pub. No. WO87/05231 PCT Pub. Date Sep. 11, 1987.The invention relates to a process for the production of a catalyzer and a catalyzer for the removal of polluting components from exhaust gases of internal combustion engines, particularly Otto-engines, by using carrier materials provided with catalytically effective metallic compounds. The catalyzer is not only simple and cost-effective to produce but also is very efficient at removing polluting components from exhaust gases, can be operated with leaded gasoline and has a comparatively long life components of the catalyzer include approx. 22-26% by weight of cobalt oxide, approx. 8-15% by weight manganous oxide, approx. 4-6% by weight copper oxide, approx. 25-35% by weight clay, and approx. 27-35% by weight talc. All these components are first premixed together in a dry powder form, homogenized and brought to the desired final particle size. Subsequently the powder mixture to be plastified is agitaled in a mixer and granulated through a sieve resultant granulate is then pressed into molds to be dried at approx. 50-150 degrees C and then burned at a temperature of approx. 850-900 degrees C.
