Interaction effects on deactivated exhaust aftertreatment catalysts run on biofuels

Today, a Euro 6 exhaust aftertreatment system for heavy duty trucks typically consists of an oxidation catalyst, a particulate filter, a catalyst for NOx reduction and an ammonia slip catalyst. Several of these catalysts are new and there is limited knowledge about their deactivation patterns, particularly about the complete system of components. In a unique collaboration between Scania CV AB, AB Volvo, Haldor Topsøe A/S, KTH and Chalmers, we now initiate a comprehensive study on future exhaust aftertreatment. The purpose of the project is to map the interaction between the different components in a typical Eu 6 aftertreatment system when aged with exhaust from heavy duty trucks operated on biofuel. The project is planned to be carried out in 4 years, and is managed by Scania and representatives from Volvo, Haldor Topsøe, KTH and Chalmers. The project is divided in 5 work packages and is formed as PhD projects with one PhD student each at KTH and Chalmers.
