摘要：
Caffeine was separated from supercritical carbon dioxide with a zeolite membrane that had been tested for pervaporation. The pore size of the NaY zeolite membrane,vas evaluated to be of subnanometer scale from the result of a Dubinin-Astakhov analysis. The rejection of caffeine was 0.98 by the zeolite membrane which would make it applicable for SCCO2 membrane separation.
