Carrier material for three-way catalysts containing Platinum Group metal with reduced tendency to the emission of H2S

摘要

The present Invention refers to a Carrier material for three-way catalysts containing Platinum Group Metal For the purification of Exhaust gases of combustion engines.In the given case is equipped with one or more non noble Metal Oxides for the purification of Exhaust gases of motor vehicles,With less tendency to the emission of H2S consisting of Activated aluminum oxide and at least 10 percent by weight of Cerium oxide,Referred to the sum of all the components of the carrier.
