Adsorption of Propene and Propane on Graphitized Carbon. II. Analysis of Single Gas and Mixed Gas Isotherms
Adsorption isotherms for propene and propane on Vulcan 3G were obtained at four temperatures between 273 and 313 K and pressures up to 1 bar, using a microbalance technique. The adsorption of the two gases, and of their binary mixtures (reported in Part 1 of this study), is analysed in terms of the...

| Summary: | Adsorption isotherms for propene and propane on Vulcan 3G were obtained at four temperatures between 273 and 313 K and pressures up to 1 bar, using a microbalance technique. The adsorption of the two gases, and of their binary mixtures (reported in Part 1 of this study), is analysed in terms of the two-dimensional Scaled Particle equation. Whereas Henry's Law constants and isosteric enthalpies of adsorption of the two gases are of nearly equal magnitude, the cross-sectional area β/L = πσ 2 /4 of propane is found to be about 10% larger, and the lateral interaction energy parameter ε more than 20% larger, than the corresponding parameters for propene. The binary adsorption system conforms to the Ideal Adsorbed Solution model by Myers & Prausnitz, and the interaction parameter α 12 for unlike molecules (α ∼ επσ 2 /4) derived from the mixture adsorption data conforms to Berthelot's mixing rule within experimental accuracy. |
