DIESEL PARTICULATE FILTER COATED DIESEL OXYDATION CATALYST AND DE-NITROGEN OXIDE CATALYST

摘要

PURPOSE: A method for manufacturing a diesel particle filter on which a diesel oxidation catalyst and a denitrification oxide catalyst are coated is provided to remove soluble organic gas and a nitrogen oxide among particle materials contained in diesel exhaust gas at the same time and to produce the small effective diesel particle filter at low costs. CONSTITUTION: A method for manufacturing a diesel particle filter on which a diesel oxidation catalyst and a denitrification oxide catalyst are coated includes the following steps of: impregnating a diesel particle filter into a diesel oxidation catalyst mixture in order to coat the diesel oxidation catalyst mixture on an exhaust gas outflow line of the diesel particle filter (S101); impregnating the diesel particle filter into a denitrification oxide catalyst mixture in order to coat a denitrification oxide catalyst mixture on an exhaust gas inflow line of the diesel particle filter (S102); drying a gel particle filter (S105); and plasticizing the diesel particle filter (S107).
