ZEOLITE CATALYST FOR PURIFYING THE EXHAUST GASES FROM DIESELENGINES

摘要

The invention relates to a catalyst for purifying the exhaust gases from diesel engines. The catalyst contains a zeolite mixture of several zeolites with different moduli and platinum group metals as well as further metal oxides from the group comprising aluminium silicate, aluminium oxide and titanium oxide, wherein the aluminium silicate has a ratio by weight of silicon dioxide to aluminium oxide of 0.005 to 1 and the platinum group metals are deposited on only the further metal oxides.
