PRODUCTION OF ACTIVATED CARBON FROM POLYACRYLONITRILE.

Abstract

The present investigation is concerned with developing a process to produce activated carbon from waste polyacrylonitrile. Polyacrylonitrile ws first heated in air at 270 degree C for 5 hr. Then the product was activated by steam in a batch fluidized bed at 800-900 degree C for 10-90 min. The yield of activated carbon was 20-27 wt%. Testing results show that the activated carbon obtained is useful for removal of mercaptan, one of air pollutants which can hardly be removed by other adsorbents.
