Hydrocarbon SCR

Emissions and Aftertreatment Technology

Hydrocarbon Selective Catalytic Reduction (SCR)

Hydrocarbon-SCR (lean NOx reduction) systems use hydrocarbons as the reductant. The hydrocarbon may be that occurring in the exhaust gas (“native`) or it may be added to the exhaust gas. This has the advantage that no additional reductant source needs to be onboard.

Expertise and experience:

Principle investigator on Department of Energy contract (~$12,000,000) for new catalytic materials development. DOE project had BASF and Accelrys as partners
High throughput reactor data mining
Reactor studies of the program catalysts
Evaluation of dynomameter evaluations of the program catalyst
