HONEYCOMB AUTO EXHAUST CATALYSTS CONTAINING COPPER CHROMITE AND PALLADIUM

A copper chromite ZRO2 honeycomb catalyst has been evaluated in the laboratory and to a limited extent on vehicles. When 650-850 grams of this catalyst (1.4-1.9 lbs.) is dispersed on two honeycombs and used to catalytically treat the exhaust of a 4500 lb, 400 in 3 Torino, the percent oxidation of CO and hydrocarbons during the Federal Test Procedure are close to, but less than that produced by present noble metal production catalysts. Catalysts containing a low level of palladium appear to offer a competitive alternative to the use of a high catalyst loading base metal catalyst. /GMRL/
