Tailoring activated carbons for the development of specific adsorbents of gasoline vapors

- High performance adsorbents of gasoline vapors as have been developed.
- The influence of their surface chemistry and porosity was determined.
- Ethanol adsorption is favored by specific interactions with carboxylic groups.
- VOC' diffusion is favored by mesopores and the adsorption capacity by micropores.
- The VOC' adsorbed is totally recovered by thermal regeneration.
