SCREENING THE ADSORPTIVE EFFECT OF METAL OXIDES NANOPARTICLES LOADED ACTIVATED CARBONS FOR SULFUR COMPOUNDS

摘要

The removal of sulfur from fuels is an important aspect innreducing air pollution. Adsorptive desulfurization is one of thenpromising methods for desulfurization. The present study utilized endnof life tires (hard to dispose waste) for the synthesis of porousnactivated carbon. Then, it was loaded with metal oxides nanoparticlesn(AC/ZnO, AC/CeO2, AC/Ni, AC/CeO2/Ni, and AC/ZnO/Ni). Theynwere tested for adsorptive desulfurization of thiophene,nbenzothiophene (BT) and dibenzothiophene (DBT) from model fuels.nThe activated carbon was characterized before and after loading withnnanoparticles. SEM images of the activated carbon before and afternloading with nanoparticles showed it micropourous, mesoporousnstructure, enhanced pore sizes and adequate dispersion of thennanoparticles. EDX and FT-IR analysis confirmed the presence ofncarbon as the main element in the synthesized material. The order ofnthe adsorbent in terms of desulfurization performance was AC
