Catalyst carrier material, catalyst carrier and preparation method thereof

[0049] Example 1

[0050] The solid aluminum chloride was added to distilled water while heating and stirring until dissolved, resulting in solution (a). The concentrated ammonia water is added with an appropriate amount of distilled water to be diluted to about 10wt% dilute ammonia water (b). The powdered coconut shell charcoal is added to the glucose aqueous solution and mixed evenly, the liquid-solid volume ratio is 3:1, and then water is added to make a slurry to obtain a slurry (c). After adding (a) to the gel-forming tank and stirring and heating to 60°C, open the valve of the container containing (b), and drop the system in the tank to pH=4.0 within 10 minutes. (c), continue to dropwise (b), and control the dropwise addition of the system in the tank to pH=8.0 within 30 minutes. Keep the temperature at 60°C, pH=8.0, age for 1 hour, filter the material in the tank, wash to no chloride ions, filter, and dry the filter cake at 110°C for 10 hours to obtain carrier material A-1, and then in nitrogen It was calcined at 550°C for 5 hours under the protection, crushed and sieved to obtain a powder carrier J-1. The amounts of reagents used for gel formation are listed in Table 1.

[0051] Take 100 grams of powdered carrier J-1, contact it with a colloidal solution containing nitric acid to form a paste, extrude it into strips, then dry it at 110 °C for 10 hours, and bake it at 550 °C for 5 hours under nitrogen protection to obtain the catalyst. Shaped carrier Z-1, whose properties are shown in Table 2.

[0052] Example 2

[0053] The solid aluminum sulfate was added to distilled water while heating and stirring until dissolved, resulting in solution (a). The concentrated ammonia water is added with an appropriate amount of distilled water to be diluted to about 10wt% dilute ammonia water (b). The powdered coconut shell charcoal is added to the glucose aqueous solution and mixed evenly, the liquid-solid volume ratio is 5:1, and then water is added to make a slurry to obtain the activated carbon slurry (c). Take a glue tank, add (a) to the tank and heat it to 60°C with stirring, open the valve of the container containing (b), and drop the system in the tank to pH=4.0 within 10 minutes, open (c) ) the valve of the container, continue to drip (b), control the system in the tank to drop to pH=8.0 within 30 minutes, and control the valve of the container of (c) to ensure that the dripping is completed at this time. Keep the temperature at 60°C, pH=8.0, age for 1 hour, filter the material in the tank, wash until there is no sulfate ion, filter, and dry the filter cake at 110°C for 10 hours to obtain carrier material A-2. Then calcined at 550° C. for 5 hours under nitrogen protection, crushed and sieved to obtain powder carrier J-2. The amounts of reagents used for gel formation are listed in Table 1.

[0054] Take 100 grams of carrier material A-2, contact it with a colloidal solution containing nitric acid to form a paste, extrude it into strips, and then dry it at 110 °C for 10 hours, and bake it at 550 °C for 5 hours under nitrogen protection to obtain catalyst molding. Carrier Z-2, whose properties are shown in Table 2. Then it was impregnated with an impregnation solution containing Ce-Cu, then dried at 110 °C for 10 hours, and calcined at 550 °C for 5 hours under nitrogen protection to obtain catalyst B, whose composition is shown in Table 3.

[0055] Example 3

[0056] The solid aluminum sulfate was added to distilled water while heating and stirring until dissolved, resulting in solution (a). The solid sodium metaaluminate is formulated into a concentration of 250g Al 2 O 3 /L sodium aluminate solution (b). The powdered coconut shell charcoal is added to the sucrose aqueous solution and mixed evenly, the liquid-solid volume ratio is 3:1, and then water is added to make a slurry to obtain a slurry (c). Take a glue tank, put it in 2L deionized water, stir and heat it to 60℃, then add the slurry (c), open the valve of the container with (a) and (b) at the same time, and control the pH of the system to be 8.0 for 45 minutes. After dripping (a), close the valve. Keep the temperature at 60°C, pH=8.0, age for 1 hour, filter the material in the tank, wash until there is no sulfate ion, filter, and dry the filter cake at 110°C for 10 hours to obtain carrier material A-3. Then calcined at 550° C. for 5 hours under nitrogen protection, crushed and sieved to obtain powder carrier J-3. The amounts of reagents used for gel formation are listed in Table 1.

[0057]Take 100 grams of carrier material A-3, contact it with a colloidal solution containing nitric acid to form a paste, extrude it into strips, and then dry it at 110 °C for 10 hours, and bake it at 550 °C for 5 hours under nitrogen protection to obtain catalyst molding. Carrier Z-3, whose properties are shown in Table 2.
