Het adsorptlevermogen Is toch al kleiner dan dat van actieve kool en wordt nog kleiner door vergiftiging In de loop van de regeneratlecycl i en verstopping door teerachtige stoffen en vaste stoffen In suspensie. ###>Indeed their adsorption capacities, which are already lower than those of PAC, were further reduced by poisoning during the regeneration cycles and by the accretion of tarry matter and suspended solids.
