ADSORPTION METHOD AND SEPARATION MEDIUM

摘要

A population of beads having a density > 1 g/cm<-3> and comprising a polymer base matrix in which a particulate filler is incorporated. The beads are characterized in that the filler particles have a density >/= 3 g/cm<-3> and in that the density and/or size of the beads are distributed within predetermined density and size ranges. Particularly important filler particles are those which have rounded shapes, for instance spheres, ellipsoids or aggregates/agglomerates thereof. The bead population is particularly usable in adsorption processes in fluidized beds, with preference to stable expanded beds.
