Embodiment 1
[0117] (1) 262g of pseudo-boehmite was added into 1.42kg of deionized water for beating and dispersion, then 23.8mL of hydrochloric acid was added for acidification for 15min to obtain the bauxite colloid, and ferric nitrate (calculated as Fe) 2 o 3 Count) 6g, cobalt nitrate (as Co 2 o 3 Count) 6g, KMnO 4 (as MnO) 10g, RuCl with a mass content of 12.5g / L in terms of metal elements 3 Add 9.6mL of the solution into 350mL of water and stir until it is fully dissolved, add bauxite colloid to it, and stir for 15min to obtain the first solution; add 10g of MgO to 30g of water, stir for 10min, then add it to the first solution, and stir for 20min to obtain the active Component coating slurries;
[0118] (2) The active component coating slurry obtained in step (1) is used to coat the cordierite honeycomb carrier (the carrier pore density is 400 holes / square inch, the opening rate of the cross section is 70%, and the shape of the hole is a square), after Dry (100°C, 4h), then tran...
Embodiment 2
[0123] (1) 253g of pseudo-boehmite was added into 1.37kg of deionized water for beating and dispersion, then 22.9mL of hydrochloric acid was added for acidification for 15min to obtain the bauxite colloid, and ferric nitrate (calculated as Fe) 2 o 3 Count) 10g, cobalt nitrate (as Co 2 o 3 Count) 6g, KMnO 4 (as MnO) 6g, RuCl with a mass content of 12.5g / L in terms of metal elements 3 Add 8.8mL of the solution into 350mL of water and stir until it is fully dissolved, add bauxite colloid to it, and stir for 15min to obtain the first solution; add 16g of MgO to 48g of water, stir for 10min, then add it to the first solution, and stir for 20min to obtain the active Component coating slurries;
[0124] (2) The active component coating slurry obtained in step (1) is used to coat the cordierite honeycomb carrier (the carrier pore density is 400 holes / square inch, the opening rate of the cross section is 70%, and the shape of the hole is a square), after Dry (100°C, 4h), then tran...
Embodiment 3
[0128] (1) 209g of pseudo-boehmite is added to 1.13kg of deionized water for beating and dispersion, and then 19.0mL of hydrochloric acid is added for acidification for 15min to obtain the bauxite colloid. 2 o 3 Count) 20g, cobalt nitrate (as Co 2 o 3 Count) 12g, KMnO 4 (as MnO) 10g, RuCl with a mass content of 12.5g / L in terms of metal elements 3 Add 10.4mL of the solution into 350mL of water and stir until it is fully dissolved, add bauxite colloid to it, and stir for 15min to obtain the first solution; add 24g of MgO to 72g of water, stir for 10min, then add it to the first solution, and stir for 20min to obtain the active Component coating slurries;
[0129] (2) The active component coating slurry obtained in step (1) is used to coat the cordierite honeycomb carrier (the carrier pore density is 400 holes / square inch, the opening rate of the cross section is 70%, and the shape of the hole is a square), after Dry (100°C, 4h), then transfer to a tube furnace, and feed CO...
