Examples
example 1
[0021] Add 80 grams of acetic acid solution with a concentration of 36 mass % into 100 grams of pseudo-boehmite powder (SB powder produced by Sasol Company, wherein the alumina content is 75 mass %, the same below) and mix, knead, and then extrude with an extruder Strip molding. The extruded strands were dried at 120°C for 12 hours, cut into 3-6 mm long particles, and calcined at 650°C for 4 hours to obtain γ-alumina a, whose physical and chemical properties are shown in Table 1.
example 2
[0023] γ-alumina was prepared according to the method of Example 1, except that 52 grams of acetic acid solution was added, and the pseudo-boehmite powder contained 4 grams of turmeric powder. The physical and chemical properties of the obtained γ-alumina b were shown in Table 1.
example 3
[0025] γ-alumina was prepared according to the method of Example 1, except that 60 grams of acetic acid solution was added. The physical and chemical properties of the obtained γ-alumina g are shown in Table 1.
