“…The drying step was important to get rid of water and moisture at 120 °C. Before the impregnation of Fe 2 O 3 and Pd on activated carbon, charcoal was mixed with nitric acid HNO 3 at room temperature for 24 h to increase reactivity and porosity of carbon. After 24 h the resultant active carbon filtered, washed many times with distilled water to remove the residual of acid in its pores and then dried at 120 °C for 2 hours.…”

This paper describe preparation of catalysts Fe 2 O 3 / Ac and Pd/ Ac by precipitation method according to the ratio cat : Ac (20:80) and evaluates their catalytic activity to remove sulfur compounds from hydrotreated gas oil. The chemical structure of the prepared catalysts were examined by X-ray diffraction (XRD) analysis, atomic absorption spectroscopy (AAS), surface area and pore volume, and thermal gravimetric analysis (TGA). X-ray fluorescence spectrometer used to determine the content of sulfur in gas oil before and after the treatment. The catalysts in this study showed an efficient removal of sulfur compounds from light gas oil reaches to more than 60% Keywords: Oxidative desulfurization, Hydrotreated gas oil, Ferric oxide over active carbon catalyst, Palladium over active carbon catalyst.

“…In addition, HDS is usually carried out under harsh conditions such as high temperature, high pressure, and high operating cost. Under such circumstances, several non-HDS methods have been explored, e.g., extraction [6,7], adsorption [8,9], oxidation [10][11][12][13][14][15][16], biodesulfurization [17], and electrochemical technology [18]. Among them, oxidative desulfurization (ODS) is considered to be one of the promising techniques for deep desulfurization of fuel, which generally takes place under mild conditions.…”

Enhanced Oxidative Desulfurization of Dibenzothiophene by Functional Mo‐Containing Mesoporous Silica

et al. 2014

Functional mesoporous Mo-SiO 2 materials were synthesized by a one-pot and facile room-temperature procedure, and characterized by X-ray diffraction, TEM, Raman spectroscopy, FT-IR, diffuse reflectance spectra, and BET analysis. The experimental results demonstrated that the mesoporous materials presented a high dispersion of molybdenum species and excellent catalytic activity for the removal of dibenzothiophene (DBT) without organic solvents as extractants. The catalytic performance on different sulfur-containing compounds was also investigated in detail. After recycling for eight times, the removal of the oxidation desulfurization system could still reach high values. GC-MS analysis detected the oxidation product of DBT. A mechanism was proposed for the absorptive oxidation process of sulfur compounds.

There is an overwhelming desire to develop new sulfide oxidation electrocatalysts that perform at low potentials and exhibit high current density for the removal and efficient sensing of sulfide. This article describes a comparative electrochemical analysis of various commercially available carbon materials and polymer/surfactant composite electrocatalysts for direct electrooxidation of sulfide in an aqueous solution. The composites were prepared from five different carbon materials multiwalled carbon nanotubes, fullerene‐C60, graphene, glassy carbon, and carbon nanofibers (CNF) and four different polymers: chitosan, polyvinylidene fluoride, Nafion, and indigenously synthesized poly[2‐(methacryloyloxy)ethyl] trimethylammonium chloride (PMTC). The carbon@polymer composites were prepared by a simple ultrasonication technique, and the electrodes were prepared by drop‐drying the prepared composite on indium tin oxide (ITO) substrates. The CNF@PMTC showed the highest positive zeta potential that allowed an accumulation of many negatively charged sulfide ions at the CNF@PMTC surface. Cyclic voltammetry was used for the electrooxidation of sulfide in an aqueous solution of tris buffer (0.05 M; pH 8.0) and KNO3 (0.1 M). The lowest sulfide oxidation peak potential (i. e., −51 mV vs. standard hydrogen electrode) with a high catalytic current response (730 μA/cm2) of the CNF@PMTC‐modified ITO electrode among the tested and previously reported carbon‐based electrode materials make it ideal for direct sulfide electrooxidation. Taking this and its simple preparation method into account, CNF@PMTC can be considered a benchmark carbon‐based electrocatalyst for sulfide oxidation.
