Patent ID: 7712308

Claim:
An emissions system for selective catalytic reduction of nitrous oxides (NO x ) in lean-burn diesel engine exhaust, the system comprising: a catalytic converter having at least one inlet, at least one outlet, and an interior working environment adapted to receive and dispel an exhaust; a source of a reducing agent comprising H 2 and CO; a catalyst disposed in the interior working environment, the catalyst comprising a compound represented by the formula: X % Pd—Y % V 2 O 5 /Z, where X is a weight percent between about 0.1 to about 2.0, Y is a weight percent between about 0.1 to about 7.0, and Z is a high surface area oxide support material, and a mixing element having a first input coupled to the reducing agent source, a second input coupled for receipt of diesel engine exhaust, and an output for injecting the diesel engine exhaust mixed with the reducing agent into the interior working environment of the converter where the catalyst reduces nitrous oxides present in the exhaust.
