Development of a durable low-temperature Urea-SCR catalyst for CIDI engines.

Conference ·
OSTI ID:972434

The summary of this report is: (1) Optimizing synthesis parameters leads to enhanced catalyst surface areas - Nonlinear relationship between activity and surface area; (2) Catalyst development performed under a staged protocol; (3) Catalytic materials with desired properties have been identified - Meet stage requirements, Performance can be tuned by altering component concentrations, Optimization still necessary at low temperatures; (4) Better activity and tolerance to SO2 - V2O5-based materials ruled out because of durability issues; and (5) Future work will focus on improving overall low temperature activity.
