Abstract
An exhaust system comprising a heat-resistant HC adsorbent comprising an MFI metallo-silicate including at least one of gallium (Ga) and indium (In) as a skeleton forming element, and a metal component ME including at least one of an alkali metal and an alkali earth metal in a content of ME≦0.05% by weight. Such an HC adsorbent has an excellent heat resistance.
Claims8
An exhaust system comprising a heat-resistant HC adsorbent comprising an MFI metallo-silicate containing at least one of gallium (Ga) and indium (In) as a skeleton forming element, and having a metal component ME comprising at least one of an alkali metal and an alkaline earth metal in a content of ME≦0.05% by weight,
- wherein said heat-resistant HC adsorbent is heat resistant in a hydrothermal atmosphere and is heat resistant at a temperature of 1000° C.,
- and wherein the heat-resistant HC adsorbent is disposed in the exhaust system.
