The adsorption behavior of VOC for resulting adsorbents was tested with toluene as an adsorbate. With adequate steam activation duration, activated carbons with a surface area of 360-950 sq m/g were developed. Further increases in the activation time destroyed the pore structure of activated carbons, which resulted in a decrease in the surface area and pore volume. Pistachio shell was a suitable precursor to produce activated carbons with large micropore area. On the other hand, mesoporous activated carbons ere easily produced from grass husk precursors as increasing activation time. The adsorption capacities increased as the inlet toluene concentration increased, and decreased with increasing adsorption temperature. This is an abstract of a paper presented at the 98th AWMA Annual Conference and Exhibition (Minneapolis, MN 6/21-24/2005). |
