Description
Technical Field
[0001] The present invention provides an efficient catalyst for 107 glue and its preparation method, belonging to the technical field of chemical catalysts. Background Art
[0002] 107 glue is widely used in many fields such as construction, coatings, adhesives, etc. Its synthesis process requires an efficient catalyst to reduce the reaction activation energy, improve the reaction rate and product quality.
[0003] Traditional catalysts have certain limitations in catalytic performance and are difficult to meet the growing industrial demands. For example, some catalysts have low activity, resulting in long reaction times and high energy consumption; or the selectivity of the catalyst is poor, producing more by-products and affecting the quality of 107 glue.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure, and an efficient catalyst for 107 glue and its preparation method are proposed to solve the above existing problems. Summary of the Invention
[0005] The purpose of the present invention is to provide an efficient catalyst for 107 glue and its preparation method to solve the problems of low activity and poor selectivity of existing catalysts, and to effectively reduce the activation energy of the 107 glue synthesis reaction, improve the reaction efficiency and product quality.
[0006] To solve the above problems, the technical solution proposed by the present invention is: an efficient catalyst for 107 glue and its preparation method. The catalyst comprises a metal active component, a carrier and an additive; the metal active component is at least one selected from copper, zinc, and nickel. Through its special electronic structure and chemical activity, the metal active component can effectively reduce the activation energy of the 107 glue synthesis reaction, promote the progress of the reaction, and there may be a synergistic effect between different metal active components, further improving the catalytic performance. The additive is a rare earth element compound.
[0007] Further, the mass proportion of the metal active component in the catalyst is 5%-20%, and the specific surface area of the carrier silica is 200-500m 2 / g
[0008] Further, the average particle size of the catalyst is 50-200 nanometers, the pore volume of the catalyst is 0.2-0.6cm 3 / g, the rare earth element compound additive is at least one of cerium oxide and lanthanum oxide, and the mass proportion of the rare earth element compound additive in the catalyst is 1%-5%.
[0009] Further, the rare earth element compound promoter is at least one of cerium oxide and lanthanum oxide. The rare earth element compound promoter can interact with the metal active component and the carrier to adjust the surface properties and electronic structure of the catalyst.
[0010] Further, it includes the following steps:
[0011] S1. Prepare the carrier suspension: Add the silica carrier to deionized water and stir to form a uniform suspension. When preparing the carrier suspension;
[0012] S2. Load the metal active component: Add the soluble salt solution of the metal active component to the suspension and stir well. In the step of loading the metal active component, the stirring time is 2 - 4 hours. Sufficient stirring time can ensure that the soluble salt solution of the metal active component fully contacts the carrier suspension, enabling the metal ions to be evenly adsorbed on the surface of the carrier;
[0013] S3. Add the promoter: Add the rare earth element compound promoter to the above - mentioned mixed solution and continue stirring. In the step of adding the promoter, the stirring time is 1 - 2 hours.
[0014] S4. Precipitation treatment: Add a precipitant to the mixed solution and adjust the pH value to 8 - 10 to form a precipitate. After adding the precipitant, the stirring time is 3 - 5 hours. Through long - time stirring, it promotes the full reaction of metal ions with the precipitant to form a uniform and stable precipitate.
[0015] S5. Wash and dry: Filter the precipitate, wash it with deionized water multiple times. The impurities on the surface of the precipitate can be removed by washing, and the drying process can remove moisture to preliminarily form the precipitate.
[0016] Further, in the step S1, the mass ratio of the silica carrier to deionized water is 1:5 - 1:10, ensuring that the carrier is fully dispersed in water to form a stable suspension system, which is beneficial to the subsequent loading of the metal active component.
[0017] Further, in the step S2, the soluble salt solution of the metal active component is at least one of copper nitrate solution, zinc nitrate solution, and nickel nitrate solution.
[0018] Further, in the step S3, the stirring time needs to ensure that the promoter is fully mixed with the metal active component and the carrier, enabling the promoter to effectively adjust the performance of the catalyst.
[0019] Further, in the step S4, the precipitant is at least one of sodium carbonate, sodium bicarbonate, and sodium hydroxide.
[0020] Further, in the step S5, it needs to be dried at 100 - 120 °C and the drying time is 10 - 15 hours.
[0021] Due to the adoption of the above technical solution, the beneficial effects of an efficient 107 glue catalyst and its preparation method of the present invention are as follows:
[0022] 1. Through the specific combination of metal active components and their synergistic effects with the promoter and carrier, the present invention effectively reduces the activation energy of the 107 glue synthesis reaction, significantly improves the reaction rate, shortens the reaction time, and reduces the energy consumption.
[0023] 2. The special structure and composition of the catalyst in the present invention make the reaction have high selectivity, reduce the generation of by-products, and improve the product quality of 107 glue.
[0024] 3. The selection of the carrier and promoter and the preparation process of the present invention ensure that the catalyst has good stability and can maintain high catalytic performance under multiple uses and different reaction conditions. Specific Embodiments
