Abstract

"PROCESSO PARA PREPARAR UM CATALISADOR DE ZIRCÈNIA, CATALISADOR DE ZIRCÈNIA E USO DO CATALISADOR". A presente invenção refere-se a métodos de produção de catalisadores que compreendem zircónia e o seu uso na redução do óxido nitroso. O catalisador tem uma resistência relativamente elevada ao esmagamento e uma densidade relativamente baixa quando comparado com os catalisadores produzidos por métodos previamente conhecidos.
