Abstract: | The CuMnOx catalysts were deep coated into polysulfonamide felts by vacuum suction to simultaneously remove the particulate and nitrogen oxides. This filter consists of a high temperature foam layer as a surface layer, a catalytic pleated felt as a medium layer and glassfiber fabric layer with high temperature phenol resin as a final layer. In this study, the effects of catalyst loading on the pleated felt, operating temperature on nitrogen oxides reduction with NH3 were mainly investigated. Tests were conducted at operating temperature range from 150 to 250 °C and at face velocity of 1 m/min. Within these ranges, NO removal efficiency was over 90% at the catalyst loading of 350 g/m2 and 200 °C. |
