Preparation of AgY zeolite and study on its adsorption equilibrium and kinetics

Preparation of AgY zeolite and study on its adsorption equilibrium and kinetics Adsorbents with Ag-doped AgY zeolite were prepared by introducing silver into the framework of NaY zeolite using a liquid-phase ion exchanged method. Adsorbents were characterized by X-ray diffraction, ICP elemental analysis, diffuse-reflectance UV/Vis spectra, scanning electron microscope, X-ray photoelectron spectroscopy, and N2-adsorption specific surface area measurements (Brunauer–Emmett–Teller). The effects of concentration of ion exchange solution and volume, ion exchanged time, and calcination temperature on AgY adsorbents activities were investigated. The adsorptive desulfurization activity of the AgY adsorbent exchanged with AgNO3 solution of 0.25 mol L−1 volume of 20 mL, ion exchanged time of 24 h, and calcined at 500 °C exhibited the best performance. Using 10 ml of model oil, 0.2 g of AgY adsorbent and an adsorption temperature of 40 °C for 30 min, the desulfurization rate reached 93.8 %. The Langmuir isotherm best represented the equilibrium adsorption data and kinetics of adsorptive desulfurization followed a pseudo-second-order model. The thiophene adsorption was found to be controlled by external mass transfer at earlier stages and by intra-particle diffusion at later stages. Research on Chemical Intermediates Springer Journals
