Abstract
| - Single-component adsorption equilibria of the n-alkane series C1− C7 on Westvaco BAX-1100activated carbon were measured over very broad ranges of temperature and pressure, spanning293−393 K and 0.06−4964 Torr, depending on the n-alkane. The 4278 data points were correlatedsuccessfully with potential theory and collapsed essentially into one characteristic curve. A usefulfunctional form of the characteristic curve was also obtained. A new potential theory approach,based on a multisegment Gaussian distribution, qualitatively predicted both the pore sizedistribution and the total pore volume of the BAX-1100 activated carbon from the adsorptionequilibria of the C3−C7n-alkanes, with errors in the total pore volume ranging between 1 and5%. This extensive data set should prove to be very useful for testing adsorbent characterizationschemes, evaluating adsorption isotherm models, estimating adsorption thermodynamic properties of these systems, and modeling adsorption processes concerning hydrocarbon separationsand purification, in general.
