Abstract

Background and aims: ETHYLBENZENE (EB) is one of the most hazardous carcinogenic VOCs that is used or produced in various industries. Thus, it is important to reduce its use and control its emissions. The aim of this study was to determine the effectiveness of MnO2/Al2O3/Fe2O3 nanocomposite coated on HZSM-5 ZEOLITE for the removal of ETHYLBENZENE vapors.Methods: Nanocomposite coated on HZSM-5 ZEOLITE was synthesized by the sol-gel method, and its morphological characteristics were determined by XRD, FTIR, and SEM.We investigated the effects of the initial concentration of contaminant, relative humidity, and residence time on the performance of the nanocomposite for the control of ETHYLBENZENE. The Response Surface method was used to estimate the main effects and these variables and their interactions so that we could optimize the number of experiments. The experiments were designed using Design Expert software, version 9.Results: The result showed that sizes of the Nano composite particles were less than 80 nanometers. The optimum condition for the removal of EB was found to be in 50% relative humidity, 19 s residence time and an initial concentration of EB of 300ppm. For this condition the nanocomposite removed 98.95% of the EB vapors.Conclusion: The nanocomposite provided high efficiency removal of EB from the gas phase or the conditions at which the study was conducted. The advantages of using the nanocomposite for this purpose include the reaction at room temperature and the ability to remove high concentrations of contaminants. The results of this study showed coating nanocomposites on HZSM-5 ZEOLITE provide an effective adsorbent for the removal of EB from the gaseous phase.
