Removal of thiophenic compounds from gasoline is a tough challenge specially in industrial scale. The structure these compounds make the removal process difficult. Dibenzothiphene as a kown representative of this family is in the center of attention in desulfurization processes. At this research study, the peel of peach as a novel biosorbent was used for adsorption desulfurization of dibenzothiophene from fuel oil. SEM was used for characterization of the biosorbent. The effect of important parameters including the amount of sorbent, time, and temperature were studied and the optimum conditions of 40 mg, 15 min, and 25 ºC were obtained respectively at which the sulfur removal (%) of 89.23 was attained. the sulfur removal (%) of 89.23 was attained.
