SORBENT FOR CLEANING SOIL AND WATER BODIES POLLUTED WITH PETROLEUM PRODUCTS AND METHOD FOR PRODUCING SORBENT Russian patent published in 2023 - IPC B01J20/22 B01J20/32 C02F1/28 

FIELD: solid bulk sorbents.

SUBSTANCE: group of inventions is related to compositions of solid bulk sorbents intended for cleaning soils and water bodies contaminated with oil products, separating and removing such pollutants. The sorbent for removing oil products is sphagnum moss treated with a silicone aqueous emulsion of ethylhydridesiloxane. In the method of making the sorbent, sphagnum moss is placed in a container with an aqueous solution of an organosilicon emulsion of ethylhydridesiloxane. Then, after the excess emulsion drains, the hydrophobic element is heat-fixed on the moss in drying cabinets. After that, it is finally dried in an oven at a temperature lower than the heat setting temperature.

EFFECT: achievement of optimal characteristics of the absorbent qualities of the modified natural sorbent, at which the modifier is of low toxicity, moisture absorption is low, and absorption or sorption of oil products and their particles is high.
