Synthesis and Characterization of Mesoporous Silica Supported Mn-Phosphomolybdate Nanocomposite for Ultra-Deep Desulfurization of Petroleum Oil Samples

A heterogeneous manganese-substituted polyoxometalates were immobilized on organosilane modified mesoporous silica for ultra-deep desulfurization of dibenzothiophene. A physicochemical investigation of the catalyst was carried out by FTIR, SEM, BET, XRD, and TEM methods. The results of XRD and FTIR...

description A heterogeneous manganese-substituted polyoxometalates were immobilized on organosilane modified mesoporous silica for ultra-deep desulfurization of dibenzothiophene. A physicochemical investigation of the catalyst was carried out by FTIR, SEM, BET, XRD, and TEM methods. The results of XRD and FTIR analyses proved that manganese was included into the structure of the catalyst, and the catalyst kept its Keggin-type structure. Due to the use of mesoporous silicate and manganese incorporation into polyoxomolybdate, the synthesized catalyst had the ability to remove sulfur-containing compounds up to 98% of petroleum derivatives. Due to the use of inexpensive materials and simple synthetic technologies, the catalyst can be manufactured in a short time and at a very low cost. This method provides a satisfactory removal of sulfur compounds from gasoline, diesel and other petroleum derivatives.
