METHOD OF PREPARING WOOD ACTIVATED CARBON Russian patent published in 1998 - IPC

Abstract RU 2106301 C1

FIELD: sorbents. SUBSTANCE: invention concerns activated carbon for carbon filter materials of moderate-sorption type and consists in that, once wood pulp is dried, pyrolysis is carried out simultaneously with activation of wood pulp involving volatile pyrolysis products as activating agent and heat aging at pyrolysis and activation temperature. Combined pyrolysis, activation, heat aging, and cooling are performed as electron-active processes, that is, they are accompanied by ground connection at potential 0.1-50 V. EFFECT: simplified process. 2 dwg, 1 tbl
