Embodiment 1
[0025] Weigh 2 tons of sodium carbonate and dissolve in water, add 7.9 tons of activated alumina carrier and 0.1 tons of titanium dioxide, and mix and stir thoroughly for 8-12 hours. Then put it at a temperature of 70-90°C for drying; finally, roast the dried absorbent at a temperature of 200-250°C for 2-3 hours at a constant temperature; and sieve the roasted samples according to engineering needs.
Embodiment 2
[0027] Weigh 4 tons of sodium carbonate to make a solution, put 5 tons of activated alumina carrier, fully mix and stir for 8-12 hours, and then put it at 70-90°C for drying; dry the absorbent at 200-250°C 2-3 hours at a constant temperature for roasting and molding; Weigh 1 ton of titanium dioxide and put it into water, stir it to make a solution, and spray it evenly on the formed absorbent, dry the absorbent prepared after spraying and press Engineering needs to be screened.
Embodiment 3
[0029]Weigh 0.5 tons of titanium dioxide into water, put 6.5 tons of activated alumina carrier, stir thoroughly for 8-12 hours, and then dry at 70-90°C; put the dried absorbent at 200-250°C , keep the temperature for 2-3 hours for roasting and molding; weigh 3 tons of sodium carbonate and put it into water, and stir it sufficiently to make a solution, then evenly spray it on the formed absorbent, dry the absorbent prepared after spraying and follow the project Screening is required.
