Abstract
In this article we present the characterization of some carbon monoliths, which have an open and permeable structure. Due to electrical and thermal conductivity of the carbon fibers these composites could be electrically desorbed. The monoliths were prepared from milled carbon fibers and a phenolic resin. The obtained monolithic composites were carbonized up to 650°C and then the composites were steam activated at 800°C. By activation, the adsorption capacity of carbon dioxide was improved. The carbon fibers composites were characterized using scanning electron microscopy, atomic force microscopy, X-ray diffraction, BET surface area analysis and volumetric measurements of gas adsorption..
