  • Publication number: 20220289928
    Abstract: A method can be used for manufacturing one or more bodies made of a porous material derived from precursors of the porous material in a sol-gel process. The method involves filling precursors of the porous material into a mold defining the shape of the body, where the precursors include at least two reactive components and a solvent, and forming a gel body. The step is then repeated so as to form several gel bodies. The gel bodies are then removed from the mold after a predetermined time in which the gel bodies are formed from the precursors of the porous material. The gel bodies are arranged adjacent to one another, a spacer is provided between two adjacent gel bodies so as to provide a clearance therebetween, and the solvent is then removed from the gel bodies.

  • Publication number: 20220041817
    Abstract: Processes for drying gel particles, in particular for producing aerogels, involve providing a suspension containing gel particles and a solvent, introducing the suspension into a column where carbon dioxide flows in countercurrent, and removing dried aerogel particles from the column. The suspension is introduced in the top region of the column and dried aerogel particles are removed in the lower region. Pressure and temperature in the column are set such that the mixture of carbon dioxide and solvent is virtually supercritical or is supercritical. The aerogel particles can be discharged via discharge vessels or continuous decompression. Aerogel particles can be obtained by such a process and the aerogel particles can be used for medical and pharmaceutical applications, as additive or carrier material for additives for foods, as catalyst support, for cosmetic, hygiene, washing and cleaning applications, for production of sensors, for thermal insulation, or as a core material for VIPs.
