The innovative catalytically active packing elements (see figure) can be produced by precipitation polymerization on a porous support, for example, Raschig rings made from macroporous glass. Compared to the conventional packing technology (i.e., Amberlyst 15 in fiberglass bags or wire mesh) for reactive distillation, these packing materials are significantly cheaper. The aim of the study was to elucidate the mass transport phenomena inside the catalysts.
