Activation process of spherical and fibrous carbon precursors for Gas phase adsorption of volatile organic compounds

Resumen

Activated carbons (ACs) are amongst the most promising materials in environmental applications. Hence, new applications are emerging constantly, which imply that the world consumption of these materials is steadily increasing. Among the different methods employed in the preparation of new carbon materials, the interest on the hydrothermal treatment for the preparation of spherical materials can be remarked due to the advantages that the spherical carbons have in comparison with granular activated carbons or powdered activated carbons. The lignocellulosic and carbohydrate materials are interesting precursors for the preparation of spherical carbons by hydrothermal treatment due to their low cost and for environmental concerns.
