Production of a Mesoporous Carbon Adsorbent from Carbon Black and Petroleum Pitch by High-Temperature Roasting and Steam Activation

摘要

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 m~2/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.
