| titleOfInvention | Method for preparing magnetic biochar from kitchen waste |
| abstract | The invention discloses a method for preparing magnetic biochar by utilizing kitchen waste, which belongs to the technical field of biochar materials and comprises the following steps: collecting the kitchen waste, naturally drying until the water content is lower than 10%, then crushing and sieving to obtain crushed materials, putting the crushed materials into a porcelain ark, putting the porcelain ark into a tube furnace, introducing nitrogen to provide an anoxic condition, and keeping the temperature at 5-10 ℃ for min ‑1 Heating to 250-600 ℃, cracking for 2-4 hours to obtain the kitchen waste biochar, and taking the kitchen waste biochar with the concentration of 40gL ‑1 ～100gL ‑1 Kitchen waste biochar and concentration of 10mmol L ‑1 ～30mmolL ‑1 Fe (b) of 3+ Salt and Cu 2+ Mixing with salt, and continuously adding 50gL of salt under stirring ‑1 ～80gL ‑1 After the strong alkaline solution reacts for 6-48 hours at the temperature of 100-200 ℃, the product after hydrothermal treatment is subjected to vacuum filtration, cleaning and drying treatment to obtain the recyclable kitchen waste charcoal, so that the kitchen waste resource utilization is realized, the environmental hazard is reduced, and good social benefit and environmental benefit are achieved. |
