| Abstract: | The study on regeneration of activated carbon saturated with benzene as a single adsorbate by supercritical CO 2 extraction was carried out.The influence of temperature,pressure,CO 2 flow rate,granularity of activated carbon and regeneration times on the regeneration efficiency and regeneration rate was investigated.The experiment results show that the activated carbon lauded with benzene can be well regenerated by supercritical CO 2 extraction. |
