Experimental results are reported on the application of a new type of activated carbon having very high specific surface area, 3000 m(2)/g, formed in granular or supported on a honeycomb board, to the recovery of chlorinated hydrocarbon solvent vapors. The activated carbon showed an excellent adsorption capacity and the type of its adsorption was found to be volume-filling. Intraparticle diffusion was found to be the same as that for conventional activated carbons, i.e. the intraparticle diffusion proceeds mostly by surface migration.
