Title
(EN) PROCESS AND REACTOR FOR PLASMA ASSISTED GAS PROCESSING
(FR) REACTEUR DE TRAITEMENT DE GAZ PAR PLASMA
Abstract
(EN)
A process and apparatus for the treatment of internal combustion engine exhaust gases in which a non-thermal plasma is used to promote the removal of particulate carbonaceous emissions via the oxidation of NO to NO2 and its subsequent reaction with the particulates.
(FR)
L'invention concerne un procédé et un appareil de traitement des gaz d'échappement d'un moteur à combustion interne, dans lequel un plasma non thermique est utilisé pour éliminer des émissions de particules de carbone par oxydation de NO en NO2 et par réaction consécutive avec lesdites particules.
