| titleOfInvention | Preparation method for high-temperature flue gas denitrification catalyst and product of high-temperature flue gas denitrification catalyst |
| abstract | The invention relates to a preparation method for a high-temperature flue gas denitrification catalyst and belongs to the technical field of flue gas denitrification. The preparation method comprises the following two steps: preparing a precursor; and preparing a catalyst. According to the technical scheme, the preparation method comprises the steps: by taking V2O5 as a main active component and Nb2O5 and MoO3 as an auxiliary active component, preparing the precursor of V2O5, Nb2O5 and MoO3; and then mixing the precursor by titanium tungsten powder taking TiO2 and WO3 as main components through extrusion molding, drying and water removal and roasting processes to prepare the catalyst. The problem that the SCR denitration efficiency is relatively low when the flue gas temperature of a coal-fired power plant is 280-300 DEG C is solved. Moreover, in the catalyst preparation process, a microwave drying technology is adopted to overcome the defect of cracking and uneven size distribution caused by temperature gradient in a conventional drying technology, so that the drying time is shortened and the production efficiency is improved. The invention further relates to a denitrification catalyst prepared by the method, so that the low-temperature activity of the catalyst is improved and the active temperature window is expanded, and the preparation method has beneficial technical effects. |
