Does silica gel absorb or adsorb water?
Silica gel does it by adsorption, which means that the water molecules adhere to the surface of the silica gel. The silica gel is a very porous component with a high number of voids that may contain water when needed.
How much water adsorption capacity does silica have?
Silica gel has an amorphous micro-porous structure with a distribution of pore opening sizes of roughly 3-60 angstroms. These interconnected pores form a vast surface area that will attract and hold water by adsorption and capillary condensation, allowing silica gel to adsorb up to 40% of its weight in water.
What is the effect of regeneration conditions on the adsorption dehumidification process in packed silica gel beds?
The uptake was increased when the regeneration time and/or regeneration temperature of the silica gel was increased. However, no significant increase on uptakes was found after 2 h regeneration. The variation of uptakes for silica gels regenerated at 80 and 90 ¡ÆC for 2 h was negligible.
What happens to silica gel in water?
Once saturated with water, the gel may be regenerated by heating it to 120 ¡ÆC (248 ¡ÆF) for 1–2 hours. Some types of silica gel will "pop" when exposed to enough water. This is caused by breakage of the silica spheres when contacting the water.
