Abstract
Official abstract text for this publication.
An object of the present invention is to provide a catalyst for treating exhaust gas adapted not only to remove CO and VOCs based on unsaturated hydrocarbons such as C 2 H 4 but also to accelerate a decomposition reaction of saturated hydrocarbons such as propane and to provide a method for producing such a catalyst for treating exhaust gas. The present invention provides a catalyst for treating an exhaust gas containing carbon monoxide and volatile organic compounds, the catalyst comprising a substrate containing a NOx removal catalyst component and a porous inorganic compound layer containing a noble metal, the layer being applied to the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a catalyst for treating an exhaust gas containing carbon monoxide and volatile organic compounds, wherein the catalyst comprises a substrate containing a NOx removal catalyst component and a porous inorganic compound layer containing a noble metal and a NOx removal catalyst, the layer being applied to the substrate; the method comprising the steps of: reducing an aqueous metal salt solution in which one or more metal salts are dissolved to prepare a metal colloidal solution; loading the metal colloidal solution on an active porous inorganic compound to form a first slurry; mixing the first slurry with a second slurry containing a NOx removal catalyst; and applying the mixture to a substrate containing a fresh NOx removal catalyst which has not been used for the removal of NOx from exhaust gas.
