CATALYST FOR REDUCING NITROGEN OXIDES

1. Catalyst material for the reduction of nitric oxides in exhaust gases in the presence of ammonia, characterised in that titanium oxide in calcined anatase modification is used as starting material and is milled together with vanadium oxide and one or several oxides of the elements tungsten, molyb...

Beschreibung
Zusammenfassung:	1. Catalyst material for the reduction of nitric oxides in exhaust gases in the presence of ammonia, characterised in that titanium oxide in calcined anatase modification is used as starting material and is milled together with vanadium oxide and one or several oxides of the elements tungsten, molybdenum, phosphorus, chromium, copper, iron and uranium and is then subjected to at least one thermal treatment.
