Activated carbon - RCE

Granular activated carbon: Granular activated carbon has a relatively larger particle size compared to powdered activated carbon and therefore a smaller outer surface. An important advantage of powdered activated carbon is the high amount of active surface per unit volume, but due to the small particle size, it causes a high pressure drop. To make rod activated carbon, powdered activated ...
