| description | The invention relates to a preparation method of a modified silica gel carrier. The silica gel carrier adopts silicate and an inorganic acid as raw materials. A silicate solution is used as a base liquid, and an aqueous solution of the inorganic acid is adjusted to adjust the pH value of the solution; a slurry-shaped ethanol-water solution of hydrotalcite is added; a carbon dioxide gas is introduced, and an organic alcohol-water solution of the inorganic acid is added to adjust the pH value of the obtained solution; and the silica gel product is obtained after a hydrothermal reaction, acidification, washing, drying and activation. The method adopts hydrotalcite modification to prepare the silica gel carrier, and improves the pore volume and distribution of the silica gel.
本发明涉及一种改性硅胶载体的制备方法，所述载体硅胶是以硅酸盐、无机酸为原料，制备过程为：以硅酸盐溶液为底液，加入无机酸溶液，调整溶液pH值；加入浆液状水滑石的乙醇水溶液；通入二氧化碳气体，加入无机酸的有机醇水溶液，调整溶液pH值；经水热反应、酸化、洗涤、干燥、活化后得到硅胶产品。该工艺通过水滑石改性制备硅胶载体，改善了硅胶的孔容及分布。 |
