The modified removal of benzothiophene using Ni-NaY Zeolite Adsorbent System

The present work was designed to synthesize novel NiNaY zeolite systems for efficient adsorption of benzothiophene. The Ni-NaY was prepared by ion-exchange method. The characterization of Ni-NaY was done by EDX, FTIR, TGA, BET, SEM, and XRD. Characterization results revealed that Ni-NaY showed an increased surface area and pore volume compared to NaY. The adsorption experiments show that the desulfurization performance of NiNaY decreases up to ۹۹%. FT-IR spectra of benzothiophene adsorption indicate that benzothiophene is mainly adsorbed on NiNaY via π electron interaction. The gas chromatography analysis (GC) was used for the calculation of the organic matter concentrations. The effect of various parameters such as adsorbent dosage, temperature and pH on the adsorption was investigated.
