Activated Carbon - High Density Skeleton

Substance description: A porous, amorphous, high surface area adsorbent material composed of largely elemental carbon, with a high skeletal density.

(Activated carbon with a high density skeleton is produced by charring and activation with steam or other gases, of various raw materials such as coconut shells, wood, peat, lignite, bituminous coal, synthetic sources and semi-anthracite.)
