According to the different VOC Emission Standards,WEIFU uses ceramic metal honeycomb and metal net as carrier,a small quantity of precious metal and rare earth as the main catalyst activate components to effectively catalyze such industrial VOC pollutants as oxydone,aldehydes,olefins,organic halogenated aromatics,and macromolecule organics.With features of low maintenance cost,high space velocity,long lifetime and high conversion rate,this catalyst uses thermal energy generated by the combustion of exhaust gas in production to reduce manufacturing cost.
