| titleOfInvention | Precipitated alumina and method of preparation |
| abstract | The present invention relates to a process for making alumina having a seeding phase and a precipitation phase. During the seeding phase, a seed mixture is formed by adding an aluminum salt to an aqueous solution followed by addition of an alkali metal aluminate to the mixture while maintaining the seed mixture, usually at neutral pH. The precipitation timing forms precipitated alumina by simultaneously adding an aluminum salt and an alkali metal aluminate to the seed mixture while maintaining the pH between 6.9 and 7.8. The recovered precipitated alumina has at least one, preferably all of the following characteristics: i) a grain size of 33 to 42 angstroms in the (120) diagonal plane (using XRD); ii) a grain d-spacing of 6.30 to 6.59 angstroms (020); iii) high porosity with an average pore diameter of 115 to 166 angstroms; iv) a relatively low bulk density of 250 to 350 kg/m 3 ; v) a surface area of 60 to 80 m 2 /g after calcination at 1100° C. for 24 hours; and vi) a pore volume of 0.8 to 1.1 cm 3 /g after calcination at 1000° C. for 1 hour. |
