Abstract
A process for simultaneously reducing the amounts of hydrocarbons, carbon monoxide and nitrogen oxides contained in the exhaust gas from an internal combustion engine in the exhaust gas from gasoline or diesel engines with high amounts of oxygen in the exhaust gas is disclosed. A high reductive effect towards nitrogen oxides is enabled by using a homogeneous aluminum silicate as a high surface area support material for the catalytically active components.
