Title
(EN) POLLUTANT-REDUCING MINERAL POLYMERS
(FR) POLYMÈRES MINÉRAUX RÉDUISANT LES POLLUANTS
Abstract
(EN)
A mineral polymer for reducing pollutants, in particular for gas absorbing, absorbing pollutant volatile organic compounds such as volatile organic hydrocarbons and/or capturing particulate pollutants. The mineral polymer may be a metakaolin-based mineral polymer with a porous or non -porous structure. The use of the mineral polymer for reducing pollutants includes for absorbing one or more pollutant gases, such as NOx (such as NO2), SOx (such as SO2) and/or CO2, for absorbing pollutant volatile organic compounds such as volatile organic hydrocarbons and/or for capturing particulate pollutants, such as those produced by diesel engines. The pollutants are removed directly from the engine exhaust, from a ventilation system, or at the road side. A method for reducing pollutants comprises the steps: (i) providing the mineral polymer; (ii) exposing said mineral polymer to one or more pollutants; and optionally, (iii) regenerating the capability of the mineral polymer to reduce pollutants. Regeneration may be carried out by washing with a solvent, or heating. The solvent may be water or another suitable solvent.

L'invention concerne un polymère minéral pour réduire les polluants, en particulier pour l'absorption de gaz, absorber des composés organiques volatils polluants tels que des hydrocarbures organiques volatils et/ou capturer des polluants particulaires. Le polymère minéral peut être un polymère minéral à base de métakaolin avec une structure poreuse ou non poreuse. L'utilisation du polymère minéral pour réduire les polluants est prévue pour l'absorption d'un ou de plusieurs gaz polluants, tels que NOx (tel que NO2), SOx (tel que SO2) et/ou CO2, pour l'absorption de composés organiques volatils polluants tels que des hydrocarbures organiques volatils et/ou pour la capture de polluants particulaires, tels que ceux produits par les moteurs diesel. Les polluants sont éliminés directement de l'échappement du moteur, d'un système de ventilation, ou au niveau de la route. Un procédé de réduction des polluants comprend les étapes suivantes : (i) fourniture du polymère minéral ; (ii) exposition dudit polymère minéral à un ou plusieurs polluants ; et éventuellement, (iii) régénération de la capacité du polymère minéral à réduire les polluants. La régénération peut être effectuée par lavage avec un solvant, ou par chauffage. Le solvant peut être de l'eau ou un autre solvant approprié.
