Abstract In the present study, simultaneous removal of the dibenzothiophene (an aromatic refractory sulfur compound) and quinoline (an aromatic refractory nitrogenous compound) from model fuel was performed using the zinc impregnated granular activated carbon (Zn-GAC). Textual properties of the adsorbent were determined by liquid nitrogen adsorption technique. Binary isotherm study revealed that the quinoline adsorption onto Zn-GAC was more favored in comparison to dibenzothiophene. Various multi-component isotherm models were used for representing the isotherm data from binary solution. Modified Redlich-Peterson model best represented the isotherm data.
