Abstract

Söz konusu bulus sadece, yüksek reaksiyon kademesine ve yüksek bir sicaklik mukavemetine haiz olan, palladyum maddesi ihtiva eden tek katmanli ve üç yönlü katalitik konvertisörle ilgilidir. Katalizatör çok küçük parçalara ayrilmis ve stabilize edilmis alüminyum oksit maddesine ek olarak, asgari bir tane çok küçük parçalara ayrilmis seryum/ zirkonyumla karistirilmis oksit ve ihtiyari olarak da yine çok küçük parçalara ayrilmis nikel oksit ve yüksek oranlarda dagilmis seryum oksit, zirkonyum oksit ve baryum oksit ihtiva eder. Palladyum katalizatörün içini tamamen kaplayacak sekilde düzgün ve esit miktarlarda dagitilmistir.
