The thermal desorption of benzene has been measured using a thermal analyzer. Pore size distributions of active carbons and carbon blacks have been determined on the basis of thermogravimetric curves using the Kelvin equation. Calculated distributions and total pore volumes have been compared with those derived from adsorption/desorption isotherms of nitrogen and benzene vapour.
