Bulk Density of Activated Carbon
Bulk density is defined as the mass of a unit volume of the activated carbon sample in air, including both the pore system and the voids among the particles. It is very useful for the estimation of the packing volume to determine the grade of carbon needed for an existing system. Powdered carbons used for decolorization usually have a bulk density in the range from 0.25 to 0.75 g/cm3 while granular grades used in gas adsorption have a bulk density of around 0.40-0.50 g/cm3.
