A Review of the Automotive Three-Way Catalyst Ageing Technology abstract
Catalyst aging is the loss of catalytic activity over time that has crucial importance in emission of three-way catalyst. Catalyst deactivation is defined as a phenomenon in which the structure and state of the catalyst change, leading to the loss of active sites on the catalyst’s surface and thus causing a decrease in the catalyst’s performance. deactivation of a three-way catalyst is typically a very slow phenomenon, a reason why a large number of catalyst ageing cycles have been developed for the relative fast testing of catalyst thermal stability. A number of non-vehicle test methods have been developed to achieve the accelerated catalyst ageing. In this paper, mechanisms of thermal and chemicaldeactivation and ageing cycle are investigated and discussed.
