Coarse-Pore Microspherical Silica Gel 20-40 Mesh for Artemisinin Separation and Purification AdsorbentCoarse-pore microspherical silica gel appears white, transparent, or semi-transparent, with a uniform microporous structure internally. It exhibits stable physicochemical properties, excellent thermal stability, and high mechanical strength. In industrial production, coarse-pore microspherical silica gel is used as a catalyst carrier and is widely employed in the refining and removal of aromatic hydrocarbons from petrochemical products. It is also utilized for the selective adsorption and separation of organic gases and liquids, as well as ion exchange to remove harmful multivalent elements from water.

It is used for moisture-proof packaging and the dehydration and purification of industrial gases. It removes organic acids and polymers from insulating oil. During industrial fermentation processes, it adsorbs high-molecular-weight proteins from fermentation products. It serves as a catalyst and catalyst carrier, among other applications.
