METHOD OF PRODUCING HYDROPHOBIC ADSORBENT FOR CLEANING NATURAL WATERS AND SEWAGE FROM OIL PRODUCTS Russian patent published in 2013 - IPC B01J20/30 B01J20/02 B01J20/22

Abstract RU 2480277 C1

FIELD: process engineering.

SUBSTANCE: invention relates to method of fabricating pelletised adsorbents. Proposed method comprises pretreatment of clarifier slimes of thermal electric power stations (TEPS) at 180-220°C, making modifying emulsion by mixing to homogeneous consistence of polymethylhydridesiloxane and liquid heat-treated slime with modifying emulsion, forming the pellets to be heat-treated at 280-320°C.

EFFECT: high-oil-capacity sorbent from TEPS wastes.
