Abstract

"COMPOSIçõES UTILIZáVEIS COMO CAPTADOR PARA NO~ x~ DE MANGANêS E DE UM ALCALINO-TERROSO E UTILIZAçãO NO TRATAMENTO DOS GASES DE ESCAPAMENTO". A invenção se refere a composições utilizáveis como captador para NO~ x~, à base de manganês e de um alcalino ou de um alcalino-terroso e sua utilização no tratamento dos gases de escapamento. Estas composições compreendem um suporte e uma fase ativa, e elas são caracterizadas pelo fato de que a fase ativa é à base de manganês e de pelo menos um outro elemento A escolhido dentre os alcalinos e os alcalino-terrosos, o manganês e o elemento A estando quimicamente ligados. Estas composições podem ser usadas em um processo de tratamento de gás tendo em vista a redução das emissões dos óxidos de nitrogênio, como captadores de NO~ x~, estes gases podendo provir de motor com combustão interna e notadamente de motor diesel ou motores que funcionam em mistura pobre."COMPOSITIONS USED AS A CAPTOR FOR THE NOX OF MANGANES AND AN ALKALINE EARTH AND USE IN THE TREATMENT OF EXHAUST GASES". The invention relates to compositions usable as a collector for NO ~ x ~, based on manganese and an alkali or an alkaline earth and its use in the treatment of exhaust gases. These compositions comprise a support and an active phase, and they are characterized by the fact that the active phase is based on manganese and at least one other element A chosen from alkali and alkaline earth, manganese and element A being chemically linked. These compositions can be used in a gas treatment process with a view to reducing emissions of nitrogen oxides, such as NO ~ x ~ scavengers, these gases may come from an internal combustion engine and notably from a diesel engine or engines that work in poor mix.
