Abstract
resumo patente de invenção: "método para revestir um filtro de particulados catalisado e um filtro de particulados". a presente invenção refere-se a um método para a preparação de um filtro de particulados de fluxo de parede catalisado em seu lado de entrada com um primeiro catalisador que tem atividade na remoção de hidrocarbonetos e monóxido de carbono residuais e que catalisa em condições de operação de motor de mistura rica, a reação de óxidos de nitrogênio com hidrogênio e/ou monóxido de carbono em amônia e catalisa em seu lado de saída com um segundo catalisador que tem atividade na redução seletiva de nox através da reação com amônia que é formada no lado de entrada. o método envolve o fornecimento de um primeiro catalisador que tem um tamanho de partícula menor que o tamanho de poro médio de parede de filtro, e um segundo catalisador que tem um tamanho de partícula maior que o tamanho de poro médio de parede de filtro, e que mistura o primeiro e o segundo catalisador em uma suspensão, que é usada para washcoating a partir da extremidade de saída. deste modo, o primeiro catalisador se difunde na parede divisória. 20186591v1patent summary: "method for coating a catalyzed particulate filter and a particulate filter". The present invention relates to a method for preparing a catalyzed wall flow particulate filter on its inlet side with a first catalyst which has activity in the removal of residual hydrocarbons and carbon monoxide and which catalyzes under operating conditions. In a rich mix engine, the reaction of nitrogen oxides with hydrogen and / or carbon monoxide in ammonia and catalyzes at its output side with a second catalyst that has activity in the selective reduction of nox through the reaction with ammonia that is formed in the input side. The method involves providing a first catalyst that has a particle size smaller than the average pore size of the filter wall, and a second catalyst that has a particle size larger than the average pore size of the filter wall, and which mixes the first and second catalysts into a suspension, which is used for washcoating from the outlet end. thus, the first catalyst diffuses into the partition wall. 20186591v1
