METHOD FOR OBTAINING SORBENT FROM PROTEIN MEAL OF GRAPE SEEDS Russian patent published in 2018 - IPC B01J20/32 B01J20/30 B01J20/24 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the production of sorbents for oil-products from waste energy of agroindustrial complex. Method for obtaining a sorbent from protein meal of grape seeds is proposed. Method comprises removing from raw material ballast substances by extraction. Extraction is carried out in two stages. At the first stage, liquid carbon dioxide at a ratio of material and solvent 1:1, at the second stage, the solvent halocarbon R-134A at a ratio of material and solvent 1:1.5 under pressure, followed by a sharp pressure drop to atmospheric. On the received carrier associate of microorganisms is immobilized by spraying an aqueous suspension of a microbiological specimen. Microzym (tm) "PetroTrit" is used as a microbiological specimen. After mixing the mixture, it is washed. Resulting sorbent is dried.

EFFECT: increase sorption and microbiological activity of the sorbent.
