Abstract
The invention discloses a catalyst carrier prepared from titanium oxide serving as a raw material. The carrier contains vanadium-titanium oxide, the specific surface area of the carrier is 80-200 m<2> / g, the pore volume is 0.3-0.5 ml / g, wherein the specific surface area of the catalyst carrier is 60-100 m<2> / g, the vanadium-titanium oxide is V2O5 / SiO2-(MoO3)x-(WO3)1-x-TiO, the usage amount of thevanadium-titanium oxide is 50-100% of the total weight of the carrier calculated according to the vanadium-titanium oxide in a final carrier, the usage amount of aluminum oxide is 0-50% of the total weight of the carrier calculated according to the aluminum oxide in the final carrier, and the catalyst carrier can be used for solving the problem that in the prior art, the environment is severely polluted in the preparation process of the catalyst carrier.
Description
technical field [0001] The invention belongs to the technical field of catalyst carriers, and in particular relates to a catalyst carrier prepared by using titanium oxide as a raw material. Background technique [0002] Nitrogen oxides (NOx) are one of the main pollutants in the atmosphere today. Environmental problems such as photochemical smog, acid rain, greenhouse effect, and ozone layer destruction caused by it, as well as its biological respiratory toxicity, have caused great harm to the ecological environment and human health. Therefore, how to effectively remove NOx has become a key issue in environmental protection today. [0003] Under oxygen-rich conditions, NH3 is used as a reducing agent to selectively reduce NOx under the action of a catalyst to generate non-toxic and harmless N2 and H2O, that is, NH3 / Urea-SCR technology, which is the most effective technology for removing stationary source NOx and mobile source NOx one. The application of NH3-SCR technology ...
