Abstract: The invention relates to a method for drying microporous particles containing fluid in which the heat required for increasing the temperature is supplied by means of convection by reducing the interfacial tension of the fluid, preferably to 0 to 1/10, especially to 0 to 1/20, pertaining to the interfacial tension of the fluid at room temperature, by correspondingly increasing the temperature when the pressure of the fluid is at a near-critical to supercritical level. The invention also relates to a method for producing microporous, spatially cross-linked particles in which said drying method is applied. In addition, the invention relates to a device for carrying out the drying method. The device comprises a pressure vessel having an inner vessel and a pressure-carrying outer vessel. Said device also comprises suited measuring and regulating devices as well as pumping and heat exchange devices, whereby the inner vessel is provided for accommodating the particles which are to be dried. A gap is provided between the inner and outer vessels.

Furthermore, microporous, three-dimensionally networked particles are prepared by a process in which the drying process is used. In addition, an apparatus is used for carrying out the drying process, the apparatus comprising a pressure container having an inner container and pressure-withstanding outer container and suitable measuring and control apparatuses and pump apparatuses and heat exchangers, the inner container being provided for holding the particles to be dried and a gap being provided between the inner container and the outer container.

Abstract: In a process for drying microporous, fluid-containing particles, the fluid-containing particles to be dried are fed as a moving bed countercurrently to a drying fluid, the interfacial tension of the fluid being reduced in comparison with the interfacial tension of the fluid at room temperature, at near-critical to supercritical pressure of the fluid, preferably to a value in the range from 0 to 1/10, in particular from 0 to 1/20, of the interfacial tension at room temperature. Furthermore, microporous, three-dimensionally networked particles are prepared by a process comprising preparation of microporous particles containing pore liquid, exchange of the pore liquid in the particles for a fluid and drying of the fluid-containing particles, the exchange and drying being carried out in the moving bed by the countercurrent method.

Process for drying microporous particles containing fluid comprises reducing the boundary voltage of the fluid preferably to 0-1/10, especially 0-1/20 of the surface voltage of the fluid at room temperature until the temperature is raised corresponding to the sub-critical or close to critical pressure of the fluid. The heat necessary for raising the temperature is added convectively. Independent claims are also included for: (A) a process for producing microporous crosslinked particles comprising: (a) forming particles containing microporous pore fluid; (b) optionally washing and/or desalting the particles using solvent and/or water; (c) optionally partially or completely exchanging the pore fluid, solvent or water in the particles forming particles containing microporous fluid; (d) drying the particles and (e) optionally removing sorbed gases and/or materials of the dried particles; (B) an apparatus for carrying out the drying process comprising a pressure vessel with an inner vessel (1) and an outer vessel (2) as well as measuring and regulating devices and pumps and heat exchangers.
