    • 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 NO 2 ), SOx (such as SO 2 ) and/or CO 2 , 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.
    • 一种用于减少污染物的矿物聚合物,特别是用于吸收气体,吸收挥发性有机化合物如挥发性有机碳和/或捕获颗粒污染物的污染物。 矿物聚合物可以是具有多孔或无孔结构的偏高岭土矿物聚合物。 矿物聚合物用于减少污染物的用途包括吸收一种或多种污染气体,如NOx(如NO2),SOx(如SO2)和/或CO2,用于吸收挥发性有机化合物等挥发性有机化合物和 /或用于捕获颗粒污染物,例如柴油发动机生产的污染物。 污染物直接从发动机排气,通风系统或路边排出。 减少污染物的方法包括以下步骤:(i)提供矿物聚合物; (ii)将所述矿物聚合物暴露于一种或多种污染物; 和(iii)再生矿物聚合物降低污染物的能力。 可以通过用溶剂洗涤或加热进行再生。 溶剂可以是水或另一种合适的溶剂。
