Abstract (en)
[origin: FR2765492A1] The invention concerns a method for treating gases to reduce nitrogen oxide emissions wherein a catalytic composition containing a catalytic phase on a support is used, characterised in that the support is based on silica and titanium oxide in an atomic proportion Ti/Ti+Si ranging between 0.1 and 15 %. The method is particularly useful for treating exhaust gases of diesel engines or of engines using a weak mixture.
