Title (EN) METHODS FOR REMOVING NOX FROM A GAS STREAM CONTAINING MORE THAN ONE GASEOUS COMPOUND
(FR) PROCÉDÉS D'ÉLIMINATION DE NOX D'UN FLUX DE GAZ CONTENANT PLUS D'UN COMPOSÉ GAZEUX
Abstract:
(EN) The invention relates to an efficient process for removing NOx, and specifically the most abundant NOx component NO, from flue gasses from e.g. large stationary sources. Said process comprises a method for converting nitric oxide (NO) from a gas stream, where the gas stream contains more than one gaseous compound. Said method comprises two steps, a) pre-mixing the gas stream with at least one low molecular mass alcohol, and b) oxidizing said NO to nitrogen dioxide (NO2) and other HxNyOz species in the presence of the low molecular mass alcohol present in the gas stream, by use of a supported ionic liquid phase catalyst at relatively low temperatures.
(FR) L'invention concerne un processus efficace pour l'élimination de NOx, et spécifiquement le composant NOx le plus abondant NO, à partir de gaz de combustion provenant, par exemple, de grandes sources stationnaires. Ledit processus comprend un procédé de conversion d'oxyde nitrique (NO) à partir d'un flux gazeux, le flux gazeux contenant plus d'un composé gazeux. Ledit procédé comprend deux étapes, a) pré-mélange du flux de gaz avec au moins un alcool de faible masse moléculaire, et b) oxydation dudit NO en dioxyde d'azote (NO2) et d'autres espèces HxNyOz en présence de l'alcool de faible masse moléculaire présent dans le flux de gaz, par l'utilisation d'un catalyseur à phase liquide ionique supporté à des températures relativement basses.
