Abstract
Mesoporous carbon adsorbent may be produced from carbon black and petroleum pitch by high-temperature roasting (at 1100°C) and subsequent steam activation. The samples obtained are compared with samples roasted at 700°C, with losses of 5–70 wt %. It is found that raising the roasting temperature increases the mesopore surface by a factor of 1.5–2.5 (to 200–300 m2/g) and reduces the micropore volume by a factor of 1.5–3.0. The adsorbent obtained may be effectively used in extracting materials from solution.
