Abstract

"COMPOSIçãO CATALISADORA CONTENDO COMPONENTES DE ARMAZENAMENTO DE OXIGêNIO". A presente invenção refere-se a um zircónio, composição que contém terra rara, que compreende componentes de zircónio, cério, neodímio e praseodímio e ao uso desta composição em uma composição catalisadora útil para o tratamento de gases para reduzir os contaminantes contidos ali e ao processo do método para fazer a composição catalisadora. O catalisador tem a capacidade de substancialmente simultaneamente catalisar a oxidação de hidrocarboneto e monóxido de carbono e a redução de óxidos de nitrogênio.
