| titleOfInvention | A kind of non-toxic rare earth type denitrification catalyst and its preparation method and application |
| abstract | The invention relates to a non-toxic rare earth denitrification catalyst and its preparation method and application. The catalyst uses the rare earth type FCC waste agent and the hydrogenation waste agent containing tungsten and molybdenum in the oil refining catalyst, and after crushing and grinding, it is mixed with high aluminum Cement and starch are extruded and solidified into a honeycomb green body; nano anatase TiO2 is grown in situ by a hydrothermal method to form a composite oxide carrier with a shell-green body structure; impregnated with rare earth, zirconium, Manganese and other active components are activated after roasting. The catalyst has a hierarchical pore system with <2nm micropores, 2-5nm mesopores and >5nm macropore stacked pores, which is conducive to the diffusion of reactants and products in the process of flue gas denitrification, and has good performance in a wide temperature range. NOx conversion activity; poisonous V 2 O 5 is not used in the preparation, which avoids the harm to the environment and personnel in each link, and reduces the conversion rate of SO 2 /SO 3 ; reduces the amount of active components and high-temperature sintering steps, and makes oil refining The waste agent is utilized as a resource, which saves the manufacturing cost and is an environmentally friendly green preparation. |
