Process for the production of catalyzers and catalyzers for the removal of polluting components from the exhaust gases of internal combustion engines

A process for the production of a catalyzer for removal of polluting components from exhaust gases of internal combustion engines by using carrier materials provided with catalytically effective metallic compounds, said carrier materials comprising the compounds of:

• approx. 22-26% by weight cobalt oxide,
• approx. 8-15% by weight manganous oxide,
• approx. 4-6% by weight copper oxide,
• approx. 25-35% by weight clay,
• approx. 27-35% by weight talc, and wherein said catalyzer is prepared by the steps comprising:
• (a) drily premixing together all of said components in powder form;
• (b) homogenizing said powder mixture to achieve a desired final size;
• (c) agitating said homogenized powder in a mixer to achieve plastification;
• (d) extruding said agitated mixture;
• (e) conforming said extruded mixture to a mold of a desired shape;
• (f) drying said molds with extruded product at a temperature of about 50.degree. to 150.degree. C.;
• and
• (g) burning said dried extruded molds at a temperature of approximately 850.degree. to 900.degree. C.

A process for the production of a catalyzer for the removal of polluting components from nitrogen oxide exhaust gases of internal combustion engines, said catalyzer comprising the components of:

• approx. 34-37% by weight of copper oxide,
• approx. 25-35% by weight of clay,
• approx. 27-35% by weight of talc, and
• wherein said catalyzer is prepared by the steps comprising:
• (a) drily premixing together all of said components in powder form;
• (b) homogenizing said powder mixture to achieve a desired final size;
• (c) agitating said homogenized powder in a mixer to achieve plastification and thereafter passing the resultant particles through a sieve for granulation into granules;
• (d) pressing said granules into molds to achieve a desired shape;
• (e) drying said molds of pressed granules at a temperature of approximately 50.degree. to 150.degree. C.;
• and
• (f) burning said dried pressed molded granules at a temperature ranging from approximately 850.degree. to 900.degree. C.
