| titleOfInvention | Vanadia-based SCR catalysts |
| abstract | The invention discloses a kind of vanadia-based SCR catalysts, to obtain Porous mixed oxide after baking mixed, then obtaining in its area load barium oxide and tungsten oxide by adding sulfur-containing oxide into Detitanium-ore-type Porous titanium dioxide.Wherein, Detitanium-ore-type Porous titanium dioxide is 65~80%, and barium oxide and tungsten oxide are 17~30%, and sulfur-containing compound is 2.0~5.0%.Vanadia-based SCR catalysts of the invention, oxysulfide inhibit the reduction of specific surface area of catalyst at high temperature, can possess hydrothermal durability.Vanadia-based SCR catalysts of the invention keep activity in a low temperature of exhaust temperature is 250 DEG C, and can ensure that high temperature durability at 700 DEG C；It is within 10% in the volume ratio of vapor, for temperature under the conditions of 700 DEG C below, after 1~12 hour of exposure, its BET specific surface is maintained at 80% or more of original specific surface area. |
