Rotary cement kiln waste gas treatment catalyst and preparation method thereof

The invention discloses a rotary cement kiln waste gas treatment catalyst and a preparation method thereof. The preparation method sequentially comprises the following steps: S1, preparing a solid solution; and S2, preparing a denitration catalyst. The preparation method has the advantages that the mechanical property and the plasticity of the catalyst can be better improved; meanwhile, the plasticity of pug of the prepared product is improved, so that the appearance quality problems of collapse and the like of the product are avoided when the pore diameter of the product is changed, and the service life of the catalyst is prolonged. 本申请公开了一种水泥回转窑废气治理催化剂及其制备方法，制备方法，依次包括如下步骤：S1 固溶体的制备；S2 脱硝催化剂的制备。本发明的优点在于够较好的提高催化剂的机械性能和可塑性性能；同时，所制备产品泥料塑性的提高，使产品改变孔径时而不会使产品出现塌陷等外观质量问题，提高了催化剂的使用寿命。
