Abstract

The present invention relates to spherical beads comprising at least one metal and/or semimetal oxide, having a mean diameter in the range from 10 to 120 μm, a BET surface area in the range from 400 to 800 m/g and a pore volume in the range from 0.3 to 3.0 cm/g, wherein the diameter of a given bead at any one point of said bead deviates by less than 10% from the average diameter of said bead and the surface of said bead is substantially smooth, and also to a process for producing these spherical beads, to a particulate catalyst comprising the spherical beads and to the use of the spherical beads as catalysts or catalyst carriers.
