METHOD OF PREPARING CARBON ADSORBENT Russian patent published in 1997 - IPC

Abstract RU 2077381 C1

FIELD: adsorbents. SUBSTANCE: pigment carbon with covering power 1.0-1.5 g/sq. cm and oil capacity 0.1-0.3 cu.cm/g containing 53-90 wt % of particles with size ranged from 800 to 300 nm and whose greatest width of cross-section exceeds averaged diameter by no more than 7-15% is mixed with composition obtained by diluting bakelite resin with butyl alcohol or polyacryloamide diluted (by 3.2-10.0 times) with dilute aqueous ethanol. Mixing is carried out until plastic mix is obtained. Mix is then stabilized by contacting with vent agent, carbonized, entered into inert gas system, and cooled. EFFECT: improved procedure. 1 tbl
