Abstract
- The adsorption isotherm data of light hydrocarbons (C5's–C7’s, pentane, hexane, and heptane), which are the main composition of gasoline vapor, onto hydrophobic hypercrosslinked polymeric adsorbent (HY-1) were measured at temperatures ranging from (293 to 323) K and pressures up to 60 kPa and compared with granular activated carbon (NucharWV-A 1100). The experimental data were fitted to the Langmuir, Freundlich, and Dubinin–Astakhov (DA) equations, respectively. The DA isotherms correlated with the experimental data within 1.85 % root-mean-square deviation (rmsd) and presented a better fitting than Langmuir and Freundlich equations. The experimental results indicated that HY-1 had good adsorption capacities for three hydrocarbon VOCs, which were about 85 % of those of NucharWV-A 1100. The average adsorption heats of three hydrocarbon VOCs onto HY-1 were smaller than those of NucharWV-A 1100, implying three hydrocarbon VOCs were adsorbed onto HY-1 more weakly and HY-1 could be regenerated more easily.
