SILICA GEL
[EIRI/EDPR/6834] J.C.: 4208XL
INTRODUCTION
Silica Gel SiO2nH2O is an important regenerative adsorbent consisting of amorphous silica. Normally it contains about 6-8% when used as descant which can absorb water to the extent of 45%. Regular density silica gel is distinguished by its extremely fine pores and it has a surface area as high as 800M2/gms of sometimes even more. This five porous structure of the product accounts for its high capacity to absorb water and other polar molecules. Selective absorption uses of silica gels are quite numinous. One of the most important is the recovery of Liquid hydrocarbon during dehydration of natural gas.
Silica gels contain, three dimensional networks of aggregated silica particles of colloidal dimension. As formed the pores are filled with the medium which is usually water in which gel is prepared removal of the liquid results in shrinkage owing to surface tension forces. Silica gels dried this way are formed merogels. If the water in the process is replaced by alcohol and the gel is heated under pressure above the critical temperature of the liquid, resulting in the disappearance of liquid-vapor interface, surface tension effects are absent and a very voluminous (dry silica gel (aerogel) is obtained.
