ABSTRACT
Changing the surface characteristics of raw materials has created new prospects for catalysts and adsorption technology. Natural and modified zeolite with trimethylchlorosilane [TMSCI] has been used to adsorb styrene. Dynamic adsorption tests were performed with a number of standard characterization techniques and zeolite particles were examined in three sizes less than 1 mm, 1-2 mm, and 2-4 mm. The gas concentration was 20 ppm, 40 ppm, and 60 ppm. Three flow rates were tested in this study 0.5 l/min, 0.75 l/min, and 1 l/min. The sorption of Styrene depended on the particle diameter size, gas flow rate, and inlet gas concentration. The optimum size for adsorption was less than 1 mm, the optimum flow rate was 0.5 l/min, and the optimum gas concentration was 20 ppm. The adsorption capacity decreased with increasing size, flow rate, and concentration of the pollutant. The adsorption by the surface-modified zeolite increased by as much as 100% compared with natural zeolite. Therefore, the surface-modified natural zeolite may be utilized for many adsorption applications. This study shows the importance of chemical surface modification and confirms similar findings of other studies
