“…A study by Harkönen et al (1994) showed that for engine and on-road ageing, the highest deactivation occurred at the front zone of a catalyst. Engine ageing followed by laboratory analysis has also been conducted by Usmen et al (1992), Zhang et al (1997), Hughes (2005), Kallinen et al (2005), He et al (2003) and Hietikko et al (2004).…”

This study identifies, and analyses, the correlation that exists in the CO light-off performance of full size canned catalytic converters and cored samples taken from the front and rear sections of the same catalyst brick. Testing was conducted under laboratory conditions, with full size samples tested using the Catagen Labcat, and testing of cored samples conducted using the Horiba SIGU 2000. From experimental tests alone, there was no clear correlation between the CO light-off activities of full size and cored catalyst samples. However, by performing simulations using the QUB global catalyst model, which accounts for the variation of precious metal dispersion and differences in the heat transfer characteristics of the test rigs, correlation was shown to be good. . During this work, he investigated the change in catalyst activity due to static and dynamic ageing, and used mathematical catalyst modelling to identify correlation between full size bricks and cored catalyst samples. His other research areas of interest include waste heat recovery.

Accumulation of phosphorus in an automotive catalyst is detrimental to catalyst performance, leading to partial or total deactivation. The deactivation model described in this paper utilises CFD to derive a one-dimensional mathematical solution to obtain phosphorus accumulation profiles down the length of a catalyst. The early work of Oh and Cavendish [1] is the basis for this study. A model output, θ, represents the fraction of
