COMPLEX CATALYTIC SYSTEM HAVING SEMI PRE FILTER AND COMPOSITION FORELIMINATING VOLATILE ORGANIC COMPOUNDS

摘要

PURPOSE: A complex catalyst system for removing an organic compound, and a complex catalyst composition are provided to improve the efficiency of a complex catalyst filter by removing micro impurities, and to extend the usage lifetime. CONSTITUTION: A complex catalyst system for removing an organic compound comprises the following: a case(100); a prefilter removing dusts from inserted air; a semi prefilter(300) formed in a cylindrical structure to remove micro-dusts smaller than the dusts from the air inserted from the prefilter; and an oxidation-reduction complex catalyst filter(400) removing volatile organic compounds in the air by adsorping and decomposing.
