Embodiment 1
[0031] A method for preparing a coated denitration catalyst with modified honeycomb activated carbon as a carrier, comprising the following steps:
[0032] (1) According to the mass ratio of 100:1:3:2:30, activated carbon powder (specific surface area is 800m 2 / g), barium fluoride, methyl cellulose, polyethylene oxide and deionized water are added to the mixer and mixed evenly to obtain plastic mud, which is added to the filter after aging overnight. The wet green body is obtained by extruding in the extruder of the mesh and honeycomb mold, the extrusion pressure is 3MPa, the number of mold holes is 50 mesh, the wet green body is dried at 80°C to constant weight, and calcined under the protection of inert gas. The calcination temperature is 600°C, and the calcination time is 5h to obtain a solid acid-modified honeycomb activated carbon carrier;
[0033] (2) According to the mass ratio of 89:5:6, titanium dioxide, vanadium pentoxide and molybdenum trioxide are mixed, and the ...

The wet green body is obtained by extruding in the extruder of the mesh and honeycomb mold, the extrusion pressure is 3MPa, the number of mold holes is 50 mesh, the wet green body is dried at 80°C to constant weight, and calcined under the protection of inert gas. The calcination temperature is 600°C, and the calcination time is 5h to obtain a solid acid-modified honeycomb activated carbon carrier;
[0038] (2) According to the mass ratio of 84:10:6, titanium dioxide, vanadium pentoxide and molybdenum trioxide are mixed, and the ...
Embodiment 3
[0041] A method for preparing a coated denitration catalyst with modified honeycomb activated carbon as a carrier, comprising the following steps:
[0042] (1) According to the mass ratio of 100:5:3:2:30, activated carbon powder (specific surface area is 800m 2 / g), barium fluoride, methyl cellulose, polyethylene oxide and deionized water are added to the mixer and mixed evenly to obtain plastic mud, which is added to the filter after aging overnight. The wet green body is obtained by extruding in the extruder of the mesh and honeycomb mold, the extrusion pressure is 3MPa, the number of mold holes is 50 mesh, the wet green body is dried at 80°C to constant weight, and calcined under the protection of inert gas. The calcination temperature is 600°C, and the calcination time is 5h to obtain a solid acid-modified honeycomb activated carbon carrier;
[0043] (2) According to the mass ratio of 79:15:6, titanium dioxide, vanadium pentoxide and molybdenum trioxide are mixed, and the...
