The Department of Energy project, “Discovery of New NOx Reduction Catalysts for CIDI Engines Using Combinatorial Techniques (DE-FC26-02NT41218)”, was initiated on August 16th, 2002 and will be completed in 2007. The project is in collaboration with the catalyst group at BASF. Participation in this project includes a wide range of personel at BASF, Accelrys and GM who will be acknowledged in the poster. This project has discovered new, lean NOx reduction catalysts for automotive applications using high throughput techniques, reactor tests on scaled up on core monoliths and engine testing of full sized catalysts. Several compositions have been downselected for engine evaluation and early results from those measurements show high conversions on the HWFET, US06 and the FTP tests. Evaluations of the effects of poisoning, thermal aging and coking of the catalysts have been developed. Discovery work on diesel catalytic materials is complete and development work on these catalysts is in progress.
