ABSTRACT:
This invention relates to a emission control device containing a catalytic material capable of reducing pollutants in the combustion gases generated from an internal combustion engine, as well as from other combusted solid and liquid fossil fuels such as coal, and is also useful for treating combustion gases generated from the incineration of landfill garbage and tire rubber, among others. The catalytic material of the present invention is highly resistant to deactivation or poisoning from contaminants in the combusted material such as leaded gasoline. The catalytic material predominantly comprises a plagioclase feldspar belonging mainly to the albite-anorthite series and contains small amounts of mica, kaolinite and serpentine, and optionally contains magnetite.
