Hydrothermally stable, low-temperature NO.sub.x reduction NH.sub.3-SCR catalyst
Patent
·
OSTI ID:1174198
A catalyst composition includes a heterobimetallic zeolite characterized by a chabazite structure loaded with copper ions and at least one trivalent metal ion other than Al.sup.3+. The catalyst composition decreases NO.sub.x emissions in diesel exhaust and is suitable for operation in a catalytic converter.
