What are the uses of supercritical aerogels?

Nanostructured aerogels can also be used as a new type of gas filtration, which is different from other materials in that the material has uniform pore size distribution and high porosity. Due to the material is particularly large than the table and product. Aerogels also have broad application prospects as new catalysts or catalyst carriers.

How does the supercritical CO2 drying device work?

Since there is no surface tension in the supercritical fluid, there is no additional pressure in the gel capillary pores caused by surface tension at this time. Therefore, the use of the gel under supercritical fluid conditions is boring, the collapse of the gel structure caused by additional pressure does not occur, the shrinkage of the gel during drilling is avoided, and the gel mesh frame structure is adhered to the ultrafine aerogel with high specific surface area, uniform particle size distribution and large pore volume.

Supercritical CO2 Drying Technology

Supercritical drying technology is the first technology to realize the batch preparation of aerogel technology, which is relatively mature, and is also the technology adopted by aerogel enterprises at home and abroad. Supercritical drying aims to reach the critical point of the solvent during the drying process through pressure and temperature control, forming a supercritical fluid. Solvents in the supercritical state have no significant surface tension and are avoided during drying of the material. Shrinkage and fragmentation in the material, thereby maintaining the original structure and state of the material, preventing aggregation and coagulation of primary nanoparticles, and preparing high-surface materials, such as nanomaterials and aerogel materials.

Supercritical carbon dioxide drying problem

More recently, samples were dried with supercritical carbon dioxide, supercritical drying, and replacing the solvent in the sample with a gas. After drying, the sample was removed and the volume was reduced by 4/5. What is the reason?

Principle of carbon dioxide supercritical fluid extraction technology

The principle of supercritical CO2 fluid extraction (SFE) separation process is based on the relationship between the solubility of supercritical fluid and its density, that is, the effect of pressure and temperature on the solubility of supercritical fluid.

Application of Supercritical Carbon Dioxide Extraction Technology

Supercritical carbon dioxide extraction technology to extract natural drugs: the use of supercritical carbon dioxide, with a special alcohol material as an entrainer, extraction of ginkgo flavonoids and ginkgolides. The extraction rate of this method is 3.4, which is 2 times higher than 1% of the solvent method. The process is short, and the operation time of the extraction batch is 11 times shorter than that of the solvent method, thus improving the work efficiency. The quality of the effective components of Ginkgo biloba leaves (28% flavonoids and 7.2 ginkgolides) is higher than the current recognized quality standards, and there is no organic solvent residue and heavy metal residue.
