Abstract
The present invention relates to a process for treating gases to reduce emissions of oxides of nitrogen. This process is of the type in which a catalytic composition is used which comprises a catalytic phase on a support and is characterized in that the support is based on silica and titanium oxide in an atomic proportion Ti/Ti+Si of between 0.1 and 15%. The process of the invention applies more particularly to the treatment of the exhaust gases from diesel engines or from lean burn engines.
