Embodiment 1
[0033] This example illustrates a retort clay containing a phosphorus component and a method for its preparation.
[0034] Mix 651.0 grams of decationized water and 883.7 grams of aluminum sol, stir, add 922.7 grams of retort earth, stir for 15 minutes, then add 42.6 grams (NH 4 ) 2 HPO 4 , stirred to obtain a slurry with a solid content of 40% by weight, and then adjust the pH of the slurry to 4.0 with ammonia water, and then aged at 25° C. for 6 hours. The slurry obtained above was spray-dried and molded, and calcined at 600° C. for 1 hour to obtain retort clay C1 containing additive components. Composition of C1, distance between bottom and surface d 001 The values and specific surface areas are listed in Table 1.
Embodiment 2
[0036] This example illustrates a magnesium-promoted retort clay and a method for its preparation.
[0037] Mix 930.2 grams of aluminum sol, 1541.7 grams of acidified pseudo-boehmite, and 692.0 grams of retort earth, make a slurry, and add 125.5 grams of MgCl 2 ·6H 2 O, stir evenly to obtain a slurry with a solid content of 30.4% by weight. The pH of the slurry was adjusted to 5.0 with ammonia water, and then aged at 25° C. for 12 hours. The above slurry was spray-dried and molded, and calcined at 450° C. for 3 hours to obtain retort clay C2 containing additive components. Composition of C2, distance between bottom and surface d 001 The values and specific surface areas are listed in Table 1.
