Embodiment 1
[0030] The conductive flue gas denitrification catalyst of this embodiment is made of the following raw materials in percentage by weight: 62% of titanium dioxide, 9% of tungsten trioxide, 1% of vanadium pentoxide, 2% of silicon dioxide, 2% of cerium, 10% of C fiber, Lactic acid 6%, grade cellulose 4% and balance are polyethylene glycol.
[0031] The specific preparation method of the conductive flue gas denitrification catalyst is as follows:
[0032] (1) Mixing: Mix titanium dioxide, tungsten trioxide, vanadium pentoxide, silicon dioxide, and cerium evenly, then add C fiber, lactic acid, grade A cellulose and polyethylene glycol, and mix;
[0033] (2) Filtration pre-extrusion: After the material obtained in step (1) was stale for 12 hours, it was filtered, and the filtered material was cooled and directly pre-extruded;
[0034] (3) Extrusion: the pre-extruded product obtained in step (2) is extruded as a whole through a mould;
