METHOD OF PREPARING SORBENT FOR REMOVING OIL FROM SOLID AND WATER SURFACES Russian patent published in 1998 - IPC

Abstract RU 2116128 C1

FIELD: oil pollution removal. SUBSTANCE: high-moor peat at low degradation degree is used as carrier after preliminary drying from 60 to 23-25% moisture content and compaction under pressure 140-150 MPa into briquets becoming water-repellent upon heat treatment. In this case, water-repellent agents are water- insoluble carbon-containing substances releasing together with water from solid organic material of peat at 250-280 C under anaerobic conditions. EFFECT: reduced cost and environmental safety preserved. 1 tbl
