Desulfurization of gas-oil onto Iraqi Using laboratory-improved clays

Desulfurization of gas-oil was investigated. The adsorption desulfurization process was carried out on a highly efficient agent using various Clay Mineral (CM) (Attapulgite and Bentonite), which were brought from the western Iraqi desert. Desulfurization processes were investigated using applying three temperatures ( 400, 500 and 550 0C) and three kinds of catalysts: firstly CM only, secondly CM + ( TiO2 or ZnO or MoO3) and thirdly Nano CM, by additive 5, 15 and 25% of minerals oxides both separately. TGA has shown the thermal stability of Clay and X-ray was used for measurement the conversion% of sulfurs, which were ( 0.95 to 0.47) using Attapulgite, (0.95 to0.54) using Bentonite, (0.95 to 0.45) using Attapulgite + 25% TiO2, ( 0.95 to 0.34) using Nano Bentonite + TiO2 and,( 0.95 to 0.29) using Nano Attapulgite + 25%TiO2 which was the best. Desulfurization results. Which reteaching the good performance of the used catalyst. Gas Chromatography (GC) techniques are used to follow-up Dibenzothiophene (DBT) which is a compound in gas-oil
