Adsorption of n-hexane vapors onto non-functionalised hypercrosslinked polymers (HYPERSOL-MACRONETTM) andactivated carbon: Thermodynamic and kinetic studies
Environmental Engineering and Management Journal › Vol. 8 › Nr. 2 AbstractThe adsorption characteristics of n-hexane vapors from gaseous stream onto two types of hypercrosslinked polymeric resins (MN 202 and MN 250), and a bituminous granular activated carbon (AC 20) was investigated. The n-hexane influent concentration ranged from 2100 to 4500 ppm and the adsorption processes were performed at 30, 40 and 50 ?C. Thermodynamic potentials ?H, ?S, and ?G and isosteric heats of adsorption were calculated from experiment performed at different temperatures (30-50?C...

Comparative study of the adsorption-desorption cycles of hexane over hypercrosslinked polymeric adsorbents and activated carbon
Environmental Engineering and Management Journal › Vol. 9 › Nr. 1 Abstract
In this work, the behavior of n-hexane vapors in the adsorption-desorption cycles of non-functionalized polymeric adsorbents (MN 202 and MN 250) and granular activated carbon (AC 20) was studied. The adsorption experiments were performed in a fixed bed column, under dynamic conditions, at 30?C and atmospheric pressure. The inlet concentration of n-hexane in the air streams was 0.115 mg/cm3 (32500 ppm) and the space velocity was 2.75 s-1. Also, desorption experiments were performed in...
