RECYCLE METHOD OF DIESEL OXIDATION CATALYST, WHICH CAN REDUCE MANUFACTURING COSTS BY USING OXIDATION CATALYST IN WHICH THE PLATINUM AND PALLADIUM ARE COATED IN CARRIER

摘要

PURPOSE: A recycle method of diesel oxidation catalyst is provided improve the purifying efficiency of the exhaust gas by removing sulfur poison.;CONSTITUTION: A recycle method of diesel oxidation catalyst comprises: a step of deciding whether an integrated distance from a fixed time is bigger than a fixed distance or not(S110); a step of increasing the temperature at the end of diesel oxidation catalyst over the fixed temperature(S130), if the integration distance from the fixed time is bigger than the fixed distance(S120); a step of deciding whether the efficiency of the diesel oxidation catalyst is smaller than the fixed efficiency or not(S170); and a step reproducing the diesel oxidation catalyst if the efficiency of the diesel oxidation catalyst is smaller than the fixed efficiency.;COPYRIGHT KIPO 2010
