Regeneration Of Silica Gel

- Jan 15, 2019 -

When the silica gel is adsorbed by water vapor or other organic substances in the medium during use, the adsorption capacity is lowered and can be reused after regeneration.

For the regeneration after adsorption of water vapor, a heating method is generally employed: the moisture is removed by thermal desorption. There are various heating methods such as electric heating furnace, flue heat heating and hot air drying. The temperature at which the blue silica gel is desorbed is generally controlled within 120, and the temperature is gradually increased. After the regenerated silica gel, need to be cooled, it can be put back into use.

For the regeneration after adsorption of organic impurities, the calcination method is generally used: the blue silica gel is gradually heated in a baking furnace, but not more than 200, after 4-8 hours. During the regeneration process, it is necessary to pay attention to gradually increase the temperature to avoid bursting of the rubber particles due to severe drying and reduce the recovery rate. At the same time, the pore structure of the silica gel after regeneration will cause different degrees of change, thus reducing the adsorption performance of the silica gel, affecting the use value, and only strictly controlling the temperature to alleviate this situation.
