| titleOfInvention | Method for producing porous silica-alumina particles |
| abstract | A method for producing porous silica-alumina particles having a high specific surface area, a high pore volume, and enhanced particle strength is provided. A step of obtaining an aqueous solution containing pseudo-boehmite alumina hydrate, a step of obtaining an aqueous solution containing silica powder, and a slurry obtained by mixing the aqueous solution containing pseudo-boehmite alumina hydrate and the aqueous solution containing silica powder to pH 7.0. 0 to 9.0, a temperature of 40 to 95° C., and a temperature of 40 to 95° C. for 10 minutes to 10 hours to obtain an aqueous solution containing the silica-alumina mixture; drying the aqueous solution containing the silica-alumina mixture to obtain porous silica; obtaining alumina particles. However, the porous silica alumina particles have a specific surface area SA measured by the BET method: 400 to 600 m 2 /g, a pore volume PV measured by the BJH method: 1.0 to 2.0 mL / g, and a pore volume measured by the BJH method Average pore diameter PD: 6 to 30 nm, mass ratio of silica to alumina: 2/98 to 70/30.
