<p>The present invention relates to a process for producing and shaping shaped bodies, in particular heterogeneous catalysts, by means of low-temperature cooling processes, characterized in that a settable and flowable composition, preferably inorganic in nature, for example a suspension of solids, is introduced as droplets of the desired shape and size into a low-temperature coolant and the frozen droplets are then converted by means of drying and/or calcination processes into the corresponding mechanically stable, solid shaped body. The present invention further relates to the shaped body itself which is obtainable by the process of the invention and the use of the process of the invention for producing and shaping shaped bodies.</p> |
