Process for the recovery of carbon dioxide used as solvent for caffeine |
摘要 |
In a decaffeination process by means of supercritical carbon dioxide, the caffeine-laden solvent CO2 is completely freed from caffeine by temperature reduction at constant pressure and can thus be fed back to the material (coffee or tea) to be decaffeinated.
