摘要

Carrier material comprises a variety of plastic bodies in the form of curved plates and/or hyperbolic paraboloids with a porous surface, where the average pore diameter can be selectively adjusted by the manufacturing process at 10-500 mu m, and the density of the carrier element is adjusted corresponding to the application between 0.7-2.5 g/cm 3>, and the plates and/or paraboloids have a ratio between the surface and volume of 2000-100000 m 2>/m 3>.
