The adsorption behaviors of n-hexane vapor onto macroporous and hypercrosslinked polymeric resins were investigated. All adsorption isotherms were nonlinear and well fitted with Dubinin-Astakov equation. The equilibrium adsorption data showed that the adsorption capacities of hypercrosslinked polymeric resin (Hyper-resin) were superior to macroporous polymeric resin (Macro-resin) for lower concentration of n-hexane; however, Macro-resin had higher adsorption capacities than Hyper-resin for higher concentration of hexane. The isosteric enthalpies of adsorption for n-hexane were calculated. The Hyper-resin exhibited much higher values of Delta H-st for n-hexane than Macro-resin at the whole loading studied, indicating that the interaction force of n-hexane adsorption onto Hyper-resin was larger than Macro-resin. The consecutive column adsorption-desorption cycles were carried out to investigate the dynamic adsorption characteristics. The results revealed that the breakthrough adsorption capacities of n-hexane onto the virgin Hyper-resin were about 105% and 43% higher than those onto the virgin Macro-resin when the initial concentrations of n-hexane were 85 mg/g and 510 mg/g, respectively. Due to higher regeneration efficiency, however, the breakthrough capacities of the regenerated Macro-resin were higher than those of the regenerated Hyper-resin for the adsorption of higher concentration n-hexane.
