Embodiment 1
[0035] (1) Preparation of alumina dry glue
[0036] Preparation of sodium metaaluminate solution concentration is 140gAl 2 o 3 / L, a total of 2.5L; the concentration of aluminum sulfate solution is 40gAl 2 o 3 / L, a total of 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, the total 1.0L.
[0037] Pre-add bottom water to the reaction tank, set the temperature of the reaction tank to 75°C, and start stirring. In the process of adding the prepared sodium metaaluminate solution and aluminum sulfate solution into the reaction tank in parallel at a certain flow rate, at the same time, add the mixed solution of sodium lauryl sulfate and hydroxypropyl methylcellulose (HPMC) in parallel to adjust The pH is 6.5. After the materials were added, an alkaline solution was added to the obtained product to adjust the pH value to 8.8, the reaction ...
Embodiment 2
[0042] Other conditions are the same as embodiment 1, just sodium lauryl sulfate is replaced by sodium octadecyl sulfate, the sodium octadecyl sulfate concentration of preparation is changed into 30g / L, HPMC is replaced by MC, and the MC concentration of preparation changes into 20g / L, A-2 carrier and catalyst AC-2 were prepared.
Embodiment 3
[0044] Other conditions are the same as in Example 1, except that the concentration of sodium lauryl sulfate is changed to 50g / L, and the concentration of HPMC is changed to 50g / L to prepare A-3 carrier and catalyst AC-3.
