METHOD FOR PREVENTING THE CONTAMINATION BY PLATINUM OF AN SCR CATALYST

摘要

Preventing the contamination of the selective catalytic reduction (SCR) catalyst with platinum in an exhaust-gas treatment system comprising an oxidation catalyst containing platinum on the inflow side of the SCR catalyst, comprises removing traces of platinum contained in the exhaust-gas stream with a material zone. The material zone is present at the outflow side of the oxidation catalyst.
