چکیده مقاله:
Increasing attention is being paid to the chemistry of diesel fuel processing. However, refineries are challenged by the harmful sulfur oxides releases into the air from the combustion of high sulfur content fossil fuels [1]. Oxidative desulfurization is an innovative technology that can be used to reduce the cost of producing ultra-low sulfur diesel (ULSD) [2]. Adsorptive desulfurization is based on the ability of a solid adsorbent to selectively adsorb organic sulfur compounds from liquid transportation fuels. Since these fuels consist of various thiophenic [3].In this work, firstly magnetic graphene oxide (MGO) was synthesized and then surface of the magnetic graphene oxide (MGO) modified by Zn. Varying concentration of Dibenzothiophene (DBT) solutions were tested with different amount of synthesized adsorbents. Concentration of each solution before and after filtration was determined by UV spectrometer. Purpose of magnetization was to ease separation of used adsorbents.
