METHOD OF PREPARATION OF OIL AND OIL PRODUCT SORBENT Russian patent published in 2008 - IPC B01J20/26 B01J20/16 B01J20/30 

FIELD: chemistry.

SUBSTANCE: invention allows recycling the polymeric waste, wastes from oil manufacturing; it can be used in elimination of the oil and oil products outflow, and in sewage treatment. The method of preparation of fine-dispersed oil and oil products sorbent is proposed, which consists in dissolution of high-molecular foamed polystyrene wastes in the organic solvent under intensive stirring at concentration range 20-35% mass by polymer; solvent distillation by exposing the mixture under vacuum, the foamed polystyrene wastes are dissolved in acetone at room temperature within 2-3 minutes; the Circulite or filtration perlite are added to this solution and stirred, the received mixture is heated till 80-100°C and the received homogenous mass is cooled, divided into small fractions and grinded.

EFFECT: method simplifies technique for sorbent preparation and reduces price.
