Examples
Embodiment 1
[0022] Wash the peanut shells, dry them naturally, put them into a crucible with a cover, and send them to a muffle furnace for slow pyrolysis after sealing. The final temperature of pyrolysis is 300°C, and the pyrolysis time is 1h. The pyrolyzed solid product was soaked in 0.1mol / L HCl solution for 12 hours, then rinsed repeatedly with distilled water for 3 times, and dried in an oven at 105°C for 12 hours. After being taken out, it is crushed into particles with a size of 0.5-1.5 cm, and then the biological carbonaceous filler 1 is made.
Embodiment 2
[0024] Wash the peanut shells, dry them naturally, put them into a crucible with a cover, and send them to a muffle furnace for slow pyrolysis after sealing. The final temperature of pyrolysis is 500°C, and the pyrolysis time is 1h. The pyrolyzed solid product was soaked in 0.1mol / L HCl solution for 12 hours, then rinsed repeatedly with distilled water for 3 times, and dried in an oven at 105°C for 12 hours. After being taken out, it is crushed into particles with a size of 0.5-1.5 cm, and then the biological carbonaceous filler 2 is made.
Embodiment 3
[0026] Wash the peanut shells, air dry them naturally, put them into a crucible with a cover, and send them to a muffle furnace for slow pyrolysis after sealing. The pyrolyzed solid product was soaked in 0.1mol / L HCl solution for 12 hours, then rinsed repeatedly with distilled water for 3 times, and dried in an oven at 105°C for 12 hours. After being taken out, it is crushed into particles with a size of 0.5-1.5 cm, and then the biological carbonaceous filler 3 is made.
