Study of Adsorption of CO2 and CH4 on Resorcinol–Formaldehyde Aerogels at High Pressures

In the present work, the synthesis of aerogels was carried out from a mixture of resorcinol–formaldehyde as the precursors. The synthesis conditions used were those adjusted to obtain micropore materials. These solids were obtained through two synthesis routes: acid and base catalysis. The obtained materials were activated with CO 2 and water vapor. It was determined that the carbonization of the aerogels obtained by the basic medium (ACB 1050) develops a greater percentage of microporosity, which decreases after the activation processes. The adsorption capacity of CO 2 and CH 4 at 50 bar on the surface of this material is 12.6 and 6.0 mmol g –1, respectively.
