Abstract
The effective diffusivities of hydrocarbons (n-pentane, n-hexane, n-heptane, n-octane, 2,2-dimethylbutane, 2,3-dimethylbutane, cyclopentane, methylcyclopentane, cyclohexane, benzene, toluene and xylenes) in commercial platinum-alumina reforming catalyst were measured using the chromatographic pulse-broadening unsteady-state technique in the temperature range 185-380 °. The heats of adsorption of these hydrocarbons were estimated from the chromatographic data. The activation energy of pore diffusion and the heat of adsorption for the various hydrocarbons varied from 1.1 to 3.4 and from 5.2 to 18.5 kcal/mole, respectively.
