SILICA GEL is a material with very stable chemical properties, which is composed of silicon dioxide and water molecules. Silica gel particles exhibit a unique microporous structure inside and possess high adsorption capacity. It has a specific surface area of about 300-500m2/g, mainly mesoporous, with pore sizes distributed between 2-50nm. The internal surface of their pores has abundant surface hydroxyl groups, mainly used for adsorption drying and pressure swing adsorption to produce CO2.
