Abstract
Porous spherical shaped small bodies of activated carbon having a diameter of from 0.1-1 mm and an inner surface of from 600-2000 mg.sup.2 /m made from milled and already activated carbon particles of a size below 60 .mu.m linked together by bridges from 10-100%, of their weight of water insoluble synthetic resins added as aqueous dispersions, and, as a result of the irregular, often splinterlike shape of the carbon particles, having gaps between these particles spread throughout the whole mass of the porous body, the size of the gaps being of the same order of magnitude as the particles themselves.
