Elucidating the Changes in Activated Carbon Pore Structure as a Result of -Butylbenzene Adsorption and its Desorption by Means of Supercritical Carbon Dioxide

Elucidating the Changes in Activated Carbon Pore Structure as a Result of -Butylbenzene Adsorption and its Desorption by Means of Supercritical Carbon Dioxide

Inverse gas chromatography was applied to characterize the changes in pore structure of activated carbon samples (commercial, de-ashed, and de-ashed and oxidized) before and after the adsorption of tert -butylbenzene, and after its desorption by means of supercritical carbon dioxide. The slit-like m...
