Abstract
Subject headings
Close
- FAME biodiesel contains some trace amounts of Na, K, P, Ca and Mg. A diesel oxidation catalyst that had been used for an entire regulatory lifetime in a heavy-duty truck was studied, to investigate whether the presence of such trace elements poisons the catalyst. The vehicle-aged catalyst contained high loadings of S, P and Na, as well as a visible layer of soot. Activity in the NO oxidation reaction was severely decreased compared to a fresh catalyst of the same type, while the CO and C3H6 oxidation reactions were less affected. Activity testing after subsequent selective trace element removal procedures was used to decouple the effect of different poisons. Sintering was observed to be the main cause of catalyst deactivation. Of the trace elements present on the catalyst, P had the largest effect on catalyst activity, while the other trace elements had little effect.
