EFFECT OF IRON ON THE MICROPORE FORMATION OFPITCH-BASED SPHERICAL ACTIVATED CARBON

The microporous texture of pitch-based spherical activated carbon(PSAC)containing iron and without iron was studied in order to investigate the effect of iron on the formation of micropore.It was showed that iron had no obvious influence on the distribution of micropore,while it made the specific surface area and pore volume of micropore decrease slightly.
