Project Focus:
Characterize a HC-SCR Ag-Al2O3 catalyst with ethanol
as the reductant.
Characterize the HC-SCR catalyst with other potential
fuel-borne reductants including various alcohols and
other oxygenated compounds.
Show proof-of-concept that ethanol and other potential
fuel-borne reductants can be removed from a reductant/diesel
fuel blend using a mild-distillation method. The objective
is to show reductant removal and subsequent use on-board
a vehicle is feasible.
Better understand the chemical mechanisms that allow
good performance with the HC-SCR system.
Explore other types of HC-SCR catalyst-reductant
combinations with potential for utilizating fuel-borne
reductants.
