A CATALYST FOR TREATING EXHAUST GAS OF DIESEL LNG DUAL FUEL VEHICLES

摘要

An exhaust gas purifying catalyst for a vehicle using both diesel and LNG is provided to dip platinum as well as palladium for a catalyst and control weight ratio of the platinum and the palladium, thereby suppressing a poisoning phenomenon caused by sulfur. An exhaust gas purifying catalyst for a vehicle using both diesel and LNG comprises the following steps. A ceramic support is coated with alumina, dried and plasticized. The support coated with a carrier is manufactured and dipped in a catalyst solution containing platinum and palladium, dried and plasticized. The platinum is dipped to weight ratio of 0.1~0.5 on a basis of 1 of the palladium.
