要約: front page image
(EN)Disclosed is an absorption catalyst (3) comprising: a carrier base material (30) which comprises at least one member selected from Al2O3, CeO2, ZrO2, TiO2 and zeolite and has a specific surface area of 30 m2/g or more; and a coat layer (31) which comprises a carrier powder comprising at least one member selected from Al2O3, CeO2, ZrO2, TiO2 and zeolite and an absorbent material capable of absorbing NOx and SOx and a noble metal both carried on the carrier powder. Since the carrier base material (30) has a large specific surface area, the amount of an absorbent material capable of absorbing NOx and SOx which is carried on the carrier base material (30) is remarkably increased. As a consequence, the amount of SOx absorbed by the absorption catalyst placed upstream to an NOx-absorbing reduction catalyst is increased and the amount of NOx absorbed at a low temperature is also increased.
(FR)L'invention concerne un catalyseur d'absorption (3) comprenant : un matériau de support de base (30) qui comprend au moins un composé choisi parmi Al2O3, CeO2, ZrO2, TiO2 et la zéolite et qui possède une surface spécifique de 30 m2/g ou plus; et une couche de protection (31) qui comprend une poudre de support comprenant au moins un composé choisi parmi Al2O3, CeO2, ZrO2, TiO2 et la zéolite, ainsi qu'un matériau absorbant susceptible d'absorber NOx et SOx et un métal noble, tous deux soutenus par la poudre de support. Comme le matériau de support de base (30) possède une grande surface spécifique, la quantité de matériau absorbant susceptible d'absorber NOx et SOx qui est soutenue par le matériau de support de base (30) est remarquablement accrue. En conséquence, la quantité de SOx absorbée par le catalyseur d'absorption placé en amont d'un catalyseur de réduction absorbant NOx est accrue, de même que la quantité de NOx absorbée à basse température.
(JA)  AlO、CeO、ZrO、TiO及びゼオライトから選ばれる少なくとも一種から形成され比表面積が30m/g以上である担体基材30と、 AlO、CeO、ZrO、TiO及びゼオライトから選ばれる少なくとも一種からなる担体粉末に、NO 及びSO を吸蔵する吸蔵材と貴金属とを担持してなるコート層31と、から吸蔵触媒3を構成した。  担体基材30は比表面積が大きいため、NO 及びSO を吸蔵する吸蔵材の担持量が格段に増大する。したがってNO 吸蔵還元触媒の上流側に配置される吸蔵触媒のSO 吸蔵量が増大し、低温域におけるNO 吸蔵量が増大する。
