METHOD OF REGENERATING SORBENT WORKED OUT IN PURIFICATION PROCESSES OF WATERS AND OIL HARD SURFACES Russian patent published in 2001 - IPC

FIELD: purification processes of waters and oil hard surfaces by pressing. SUBSTANCE: method involves regeneration of sorbent prepared by moisture removal of up to 20-48% from organomineral raw material with moisture content not higher 60% by mechanical dehydration with the following heat treatment without oxygen access in inert gas media for 20-90 min at temperature 15-30 C higher than that of separation of water-nonsoluble resins from raw material. Mixture of worked out sorbent and organomineral filler is subjected to pressing at their mass ratio provided equality of per cent content of hydrocarbons in regenerated sorbent and filler after mixture pressing with intensification up to 10 MPa. Used as a filler is material with sorption ability no less 0.5 g/g by liquid hydrocarbons, for example, hard ground fuel. Product prepared as a result of sorbent regeneration may be used as carbon-containing fuel, and may be realized in places of damage with low energy expenditures. EFFECT: higher efficiency. 4 cl
