METHOD FOR PRODUCING SORBENT FROM BIOCHAR AND MYCORRHIZA FOR CLEANING SOIL FROM OIL POLLUTION Russian patent published in 2023 - IPC B01J20/20 B01J20/22 B01J20/30 B09C1/10 

FIELD: environmental protection.

SUBSTANCE: invention can be used to clean the soil from oil products. A method for obtaining a sorbent is presented, including the production of biochar from raw materials, its drying, thermal processing, oxidative pyrolysis of raw materials, characterized by the fact that forestry waste is used as a raw material for biochar: in the form of sawdust, wood shavings, chips, pyrolysis of the raw material is carried out at a temperature 750°C, the resulting biochar is crushed and passed through a sieve with a diameter of 3-5 mm, kept at room temperature 19-25°C for 24 hours, then mixed with crushed and dried arbsucular mycorrhiza 0.5 mm in size in a ratio of 1:1.
