| titleOfInvention | preparation method of vanadium-based oxide SCR catalyst and catalyst prepared by preparation method |
| abstract | The invention discloses a preparation method of a vanadium-based oxide SCR catalyst and the prepared catalyst. During the preparation process, a dispersing agent is added to react with a vanadium source and a tungsten source well to generate a more stable multidentate chelate structure, and the interaction and the coordination of the multidentate chelate structure reach an optimal state and are dispersed on the surface of a titanium dioxide carrier; the assistant increases the acidity of the surface of the catalyst, enhances the adsorption of ammonia molecules, is embedded between vanadium-tungsten ion groups to interact with the vanadium-tungsten ion groups, and inhibits the aggregation of vanadium-tungsten particles in the aging process; the additive pulls the spaces among various particles in the slurry apart, so that the mutual dispersibility and stability among the titanium dioxide particles, the active components, the auxiliary agents and the adhesives which are dissociated in the slurry are greatly improved, the coating of the slurry and the uniformity of the coating are facilitated, and the diffusion and the reaction of gas molecules are facilitated; the combined utilization, the simultaneous action and the mutual influence of the technologies improve the low-temperature activity of the catalyst and also obviously improve the hydrothermal stability. |
