Abstract: A process for producing a shaped body comprising at least one porous oxidic material and at least one metal oxide comprises the following step (i): (i) mixing the porous oxidic material or materials with at least one metal oxide sol which has a low content of alkali metal and alkaline earth metal ions and/or at least one metal oxide which has a low content of alkali metal and alkaline earth metal ions.

Abstract: The invention relates to a process and an apparatus for preparing active ingredient dispersions, wherein an active ingredient is dissolved in a fluid gas, the fluid gas loaded with active ingredient is essentially completely dissolved in a liquid and is decompressed, and the gas is separated from the liquid loaded with active ingredient.

Abstract: The invention relates to a process and an apparatus for producing stably fine-particle powders. The invention starts from a process for producing stably fine-particle powders in which one or more substances A and one or more substances B are dissolved in supercritical fluids, and the solutions are decompressed along a holdup section. In the process, substances A and B are each dissolved in separate supercritical compressible fluids, and the holdup sections interpenetrate, with the solubility limit of A in the appropriate fluid being exceeded at an earlier time than is the solubility limit of B in the appropriate fluid.
