Title (EN) COLD OXIDATION IN GASEOUS PHASE
(FR) OXYDATION A FROID EN PHASE GAZEUSE
Abstract:
(EN) A vapour and gaseous effluent purification process wherein the gaseous flow is made to proceed between metal plates (1) subjected to oscillating electrical high voltages and then over a porous siliceous mass (2) having adsorbed therein an oxidation catalyst active at room temperature.
(FR) Procédé d'épuration de l'effluent gazeux et de vapeur, dans lequel l'on fait couler le gaz entre des plaques métalliques (1) soumises à des tensions élevées oscillantes, puis on le fait passer sur une masse siliceuse poreuse (2) dans laquelle est absorbé un catalyseur d'oxydation qui est actif à la température ambiante.
