Product: Silica Gel FNG
CAS NO: 112926-00-8
Molecular formula: SiO2
Properties:
White or light gray pellet. Processed and formed from powders. Besides the adsorption feature possessed by ordinary silica gel. FNG silica gel possessed good water-tolerant property, low break-down rate of reclamation and long service, etc.
Application:
Mainly used for drying in the air separating process, the adsorption of acetylene in preparation of liquidified air and liquidified oxygen. It is also used as drying compressed air and various industrial gases. In petrochemical industry, electric power industry, brewing industry and other industries, etc. It is used as liquid adsorbent and catalyst carrier. It may also be used as the buffer drier, silica sand etc. for ordinary silica protective bed.
