At present, the increase of air pollutant gases in the atmosphere and climate changes is one of the most serious and main problems which endanger human life and the environment. Hence, in recent decades, reducing of the sulfur compounds in fossil fuels has been noticeably more considered. The physical and chemical properties of the samples were characterized by sulfur analysis, XRD, SEM, BET, FT-IR and SEM techniques. This research concentrated on an economic, green and practical process to eliminate sulfured compounds from liquid fuels such as gas oil, by using a novel porous nano silica adsorbent. By applying chemical methods and performing modification on the surface of a kind of nano silica adsorbent including deposition of iron, significant adsorption of thiophene and its derivatives were observed. The presence of the iron on the silica absorbent bed cause creating bonding between the sites and the iron atoms and makes considerably removing unsatisfied sulfur molecules. In comparison with other typical desulfurization processes like HDS, this method works on an ambient condition and on the other hand some hard processing conditions and also expensive catalysts are not essential to accomplish a satisfied and effective desulfurization.
