Description
Summary:When large volumes of gas have to be treated pressure drop limitations may arise from the use of conventional adsorption beds. For these applications conformation of the adsorption bed as honeycomb monoliths take advantage of the almost null pressure drop caused by these open channel structures. Commercially available microporous activated carbons, a mesoporous alumina and non-porous titania were conformed as honeycomb monoliths by addition of a silicate clay binder. The textural and mechanical properties of these monoliths were determined. The results were analysed together with the adsorption capacities towards chlorinated and non-chlorinated aromatic and aliphatic probe molecules and water vapour to establish the relationship between their textural properties and their adsorptive behaviours.
