A simple, economical process is disclosed for regenerating granular activated carbon, using a combination of alcohol, alkali, and oxidant, preferably ethanol, sodium hydroxide, and hydrogen peroxide. The regeneration process employs inexpensive compounds, is wellsuited to be implemented onsite, and does not require spent carbon to be transported to a specialized facility for regeneration.

Activated carbon exhibits rapid adsorption velocity, but it has a far lower gasadsorption quantity than MOFs; thus, activated carbon separates CO 2 /CH 4 inefficiently compared with the MOFs. Finally, elution time is an important index for evaluating a material's gasseparation performance.
