Lignite Base Activated Carbon Overview

Lignite coal, “often referred to as brown coal, is a soft brown combustible sedimentary rock formed from naturally compressed peat.” (Wikipedia) It is used as a base product for the manufacture of granular activated carbon (GAC).  Compared to coal and coconut base carbons, it lighter in weight (lbs. per ft3), lower in iodine number and higher in molasses number.

Benefits & Advantages

Lignite base GAC pores are large making it useful for the reduction of similarly sized contaminants such as color pigments.  Activated carbon adsorbs contaminants (adsorbates).  The adsorbates stick to the pore; they are not absorbed into the carbon.
