These catalysts, contained in so-called catalytic converters in the exhaust system of automobiles, promote the oxidation of CO and HC to CO. and H.O under net oxidizing conditions (.. A/F > 14.6). Until 1978, emission control requirements

Wirtschaftswissenschaft und Ethik,5]. Aging of catalysts by tests on a dynamometer allows catalyst durability to be measured under precisely controlled conditions and possibly completed in fewer days (by running 24 h days) than for vehicle aging. Dynamometer-controlled engine facilities are used for accelerated aging in which the ca

The reasons for choosing alumina supports for the noble metals include high surface area, attrition resistance, stable structure under typical exhaust conditions, favorable pore structure, and adequate supply . Both support types have perceived advantages and disad
