ABSTRACT:
A catalyst is disclosed for combustion of pollutants contained in the exhaust gases of internal combustion engines operated with alcohol. The catalyst consists of a metal carrier, a coating deposited on it made of a catalytically active aluminum oxide and an amount of palladium deposited on said coating. A production process for the catalyst is described which provides a final activation in oxidizing atmosphere or a formation in the stream of the exhaust gas that is to be purified at certain temperatures as well as the use of the catalyst for the simultaneous elimination of aldehydes, alcohols, carbon monoxide and hydrocarbons present in the exhaust gas.
