The corrugated plate denitration catalyst uses glass fiber as the skeleton, and the active substance is coated on the glass fiber board by impregnation, so as to achieve the purpose of denitration。Due to its large specific surface area and light weight, it is widely used in some industries where the flue gas is relatively clean (low dust content), including the gas engine, fuel engine and petrochemical industry (such as PDH), compared with the traditional plate denitrification catalyst and honeycomb denitrification catalyst are more popular。
