Silica Gel Reactivation
Information
Question | How can I reactivate or regenerate silica gel desiccant that has absorbed moisture? |
Answer |
One benefit of silica gel desiccants over zeolites is the ease of regeneration. Since silica gel will release absorbed moisture when heated to temperatures exceeding 212oF it can easily be regenerated in a common laboratory oven or furnace. To regenerate a silica gel, simply put the gel into a heat resistant container (e.g. glass or metal) and spread it out. Place the silica gel into a oven heated to between 275oF and 300oF. Leave the silica gel in the oven for at least 60 minutes per pound. It is better to heat it longer than to take it out too soon. Remove the silica gel from the oven and allow to cool in a sealed desiccator or glass jar. One or more of the following factors can affect effective silica gel reactivation:
