Abstract

Air pollution is a global concern because it can contribute to serious health and environmental impacts. Various techniques have been used to mitigate air pollution. One of the popular techniques is adsorption. This research studied hexane vapor adsorption by adsorbents prepared from a mixture of kapok fiber and waste from rayon industry in fixed bed. The Effect of physical parameters, such as adsorbent types, gas flow rate and packing styles on adsorption efficiency was investigated and the results were compared to commercial adsorbents. Kapok fiber is a hollow fiber and has hydrophobic characteristics that are advantages for use as adsorbent because of the high surface area and the affinity for organic compounds. Rayon fiber is used to improve the strength of adsorbents. The adsorbent was prepared by various concentrations of phosphoric acid, 10, 30 and 50 percent. The adsorbents characteristics, including structure, chemical composition, surface area, humidity and density were determined by SEM, FT-IR, Surface analyzer and Hot air oven method. The hexane concentration was analyzed by Gas chromatography. The results show that the suitable flow rate for hexane adsorption is 2 L/hr. and hexane adsorption efficiencies of kapok, rayon, mixed and sandwich fibers are 80, 35, 15 and 40 percent, respectively.
