[0035] The preparation method of the iron-titanium-based low-temperature denitration catalyst is to use the above solid solution as the matrix material, and at the same time add the matrix material, glass fiber, wood pulp, binder, silica, wollastonite, deionized water and ammonia water, etc. in sequence. The mass percentage is 50-65: 5-8: 1-5: 0.5-2: 3-5: 1-3: 20-30: 5-10, mixing, filtering, extruding, drying and roasting. The speed of mixing is 200-400r / min, the time is 4-6h, the pressure of filtration is 4-6MPa, the pressure of extrusion is 4-6MPa, the drying condition is 50-60℃, the drying time is 168-240h, and the calcination temperature is 450~550℃, the calcination time is 20~30h.
[0036] Since vanadium pentoxide, iron trioxide, copper oxide and titanium dioxide are combined in the form of ionic bonds, the solid solution prepared by this combination method is extremely stable, and the iron-titanium-based low-temperature denitrification catalyst used to prepare it can be ...
