Example Embodiment
[0034] Example 1
[0035] (1) Preparation of alumina dry glue
[0036] The concentration of sodium metaaluminate solution is 140gAl 2 O 3 / L, total 2.5L; the concentration of aluminum sulfate solution is 40gAl 2 O 3 / L total 5.0L; in the mixed solution of sodium lauryl sulfate and hydroxypropyl methylcellulose (HPMC), the concentration of sodium lauryl sulfate is 1.0g / L and the concentration of HPMC is 1.0g / L, total 1.0L.
[0037] Pre-add bottom water to the reaction tank, set the temperature of the reaction tank to 75°C, and turn on the stirring. In the process of adding the prepared sodium metaaluminate solution and aluminum sulfate solution co-currently into the reaction tank at a certain flow rate, while co-currently adding the mixed solution of sodium lauryl sulfate and hydroxypropyl methylcellulose (HPMC), adjust The pH is 6.5. When the addition of materials is completed, an alkaline solution is added to the obtained product, the pH is adjusted to 8.8, the reaction temperatu...
Example Embodiment
[0041] Example 2
[0042] Other conditions are the same as in Example 1, except that sodium lauryl sulfate is replaced with sodium octadecyl sulfate, the prepared sodium octadecyl sulfate concentration is changed to 30g / L, HPMC is replaced with MC, and the prepared MC concentration is changed to 20g / L, prepared A-2 carrier and catalyst AC-2.
Example Embodiment
[0043] Example 3
[0044] Other conditions were the same as in Example 1, except that the concentration of sodium lauryl sulfate was changed to 50 g / L, and the concentration of HPMC was changed to 50 g / L to prepare A-3 support and catalyst AC-3.
