ACTIVATED CARBONS MOLECULARLY ENGINEERED

摘要

A highly microporous adsorbent material is formed as a composite of a natural or synthetic clay or clay-like mineral matrix intercalated with an active carbon. The mineral is prepared and selected to have a selected interlayer spacing between microcrystalline sheets. An organic polymeric precursor is contacted therewith to fill the matrix interstices. Then the precursor is polymerized and carbonized to yield the adsorbent material in which the carbon is intercalated into the mineral matrix. The mineral can be naturally occurring smectite or synthetic hydrotalcite.
