Abstract

Background and Objective: TOLUENE is one of the most important pollutants in various industries such as petrochemicals. Absorption of solvents on the substrate is an effective control method for volatile organic compounds. The purpose of this study was to determine the effect of SILVER NANOPARTICLES on the absorption capacity of (ultra-stable Y) USY ZEOLITE in the process of TOLUENE vapor absorption from the airflow.Materials and Methods: The Ag/USY catalyst composition was prepared using an impregnation method, and 1 g of each adsorbent was placed in a quartz glass cylinder with a length of 25 cm and an inner diameter of 10 mm. In order to maintain a dynamic flow of TOLUENE vapor in the reactor, the impregnation method was used. Input and output TOLUENE concentrations were measured using a direct reading instrument. Effectiveness of the absorbents was determined based on breaking point and adsorption capacity.Results: Dynamic TOLUENE vapor with a concentration of 40 ppm and airflow rate of 0.5 L/min was fully absorbed by 1 g of USY and Ag/USY containing SILVER NANOPARTICLES (3.9%) in 465 and 873 minutes. Afterwards, the breaking point occurred and absorption gradually decreased, such that the breaking point was saturated at 153 and 162 minutes, respectively, and the concentration of TOLUENE vapor in the reactor outlet was equal to the baseline value.Conclusion: Our results showed that Ag/USY adsorbent containing 3.9% of SILVER NANOPARTICLES only had a higher breaking time and absorption rate relative to zeolite.
