ABSTRACT

Electrical Swing Regenerable Filtration Using Carbon Fibre Composites and Carbon Monoliths   [open pdf - 416KB]

"The potential of both carbon-bonded carbon fibre composites and phenolic resin based carbon monoliths for regenerable filtration applications in Collective Protection (COLPRO) has been investigated. Both are highly microporous materials and therefore have excellent adsorption properties, in addition, both materials conduct electricity due to their continuous carbon skeletons and therefore can be heated by applying a potential difference across them. Research into identifying the optimum properties required for use of these materials as regenerable adsorbents has been carried out. The results show that for the composites, the adsorption properties are influenced by both the binder content and level of activation. The composite density determines the electrical resistance, and hence the efficiency with which they can be heated for regeneration. The effect of varying the current and time period used for regeneration suggests that a short pulse at higher current regenerates the composite more efficiently than a longer pulse at lower current. The carbon monoliths have excellent adsorption properties with a very low associated pressure drop. Initial studies suggest that they are highly conducting materials with excellent adsorption properties."
