Abstract

Background and Objectives: Benzene, toluene and Xylenes (BTX) are organic pollutants, which are mainly associated with oil and its derivatives. BTX is environmental contaminants and considered harmful to human health. Application of surface absorbents such as ZEOLITE is one of several methods for the removal of these compounds. In this study, BTX compounds’ removal efficiencies were investigated and compared by using CLINOPTILOLITE type ZEOLITE and ZEOLITE with copper oxide NANOPARTICLES.Materials and Methods: In this study, the modified ZEOLITE by hydrochloric acid in the grain size 1-2 mm and modified ZEOLITE with nano particle of copper oxide were used. Artificially-Contaminated Air flow was used continuously.To determine BTX concentrations, samplings were done by charcoal tube in current input and output. The concentrations of contaminants were determined by gas chromatography with FID detector.Results: Removal efficiency of benzene, toluene, p-xylene, m-xylene and o-xylene by CLINOPTILOLITE were 78.3%, 62.1%, 32.2% 32.15% and 18.8%, respectively. For the CLINOPTILOLITE containing cooper oxide nano particles efficiency were 25.42%, 35.65%, 36.33%, 33.24% and 29.39%, respectively.Average removal efficiency of BTX compounds observed when the ZEOLITE without NANOPARTICLES used (43.31%) was more than ZEOLITE with NANOPARTICLES (32%). The results showed that the concentration of CO2 in the outlet air of the ZEOLITE-containing nanoparticle (550 ppm) was more than the ZEOLITE without nanoparticle (525 ppm).Conclusion: Results showed that adding NANOPARTICLES to the ZEOLITE, although the removal efficiency of benzene and toluene can be reduced. The results showed that adding NANOPARTICLES to the ZEOLITE, although can be reduced removal efficiency of benzene and toluene, which may be due to occupying or blocking of the pollution absorption sites by the NANOPARTICLES on the ZEOLITE, but It cause promote more catalytic effect of ZEOLITE in the decomposition process of contaminants by breaking the molecules of pollutants and their further degradation progress is done for conversion to carbon dioxide.
