Activated carbon shape
There are hundreds of active carbon types and grades. They differ by shape, pore structure, internal surface structure, purity, and others.
Different shapes for different processes:
Powdered activated carbons
The most common size,200 mesh ,325 emsh.
Granular (crushed and screened)
The most common size are 8x30,12x40 and so on.
These carbons are usually used for fluid purification.
Pellet (extruded) activated carbons
extruded activated carbon mostly consists of 1.5 mm to 4- or 5-millimeter
sized pellets
Extruded and cylindrical-shaped particles are mainly used in gas phase applications
as they have low pressure drops, high mechanical strengths.
Different pore structures for different adsorptive properties:
Types with different micro-, meso-, and macro-porosities
Effective for different sizes of impurities, and also influencing adsorption kinetics
Different internal carbon surface structures, often leading to different:
Chemical effects (electrostatic, chemisorption, and/or catalytic)
Physical effects (hydrophilicity, adsorbate shape selectivity)
Different purities, with most common differences in:
Overall ash content, and more importantly:
Contents of traces of metal salts that might be released during the application, or influence adsorbed molecules that are to be recovered
