Deep Desulfurization of Transportation Fuels with Nanoreactions
Burning sulphur-laden transportation fuels results in misty and fuggy air of large cities. The combustion products of sulphur-laden fuels poison the exhaust conversion catalyst and invalidate the catalyst box. As results, the vehicle emission gets worse and worse no matter how advanced the auto technology is. Some sulphur compounds converted to sulphates after combustion and emitted into the at...
متن کاملBiocatalytic desulfurization (BDS) of petrodiesel fuels.
Oil refineries are facing many challenges, including heavier crude oils, increased fuel quality standards, and a need to reduce air pollution emissions. Global society is stepping on the road to zero-sulfur fuel, with only differences in the starting point of sulfur level and rate reduction of sulfur content between different countries. Hydrodesulfurization (HDS) is the most common technology u...
متن کاملDesulfurization of Saudi Arabian crudes by oxidation–extraction method
The oxidation-extraction desulfurization of Saudi Arabian crudes was conducted with hydrogen peroxide-acetic acid oxidation system. The selection of extractant, the optimization of oxidation-extraction conditions, and the exploration of desulfurization mechanism were studied. As DMF was used as the extractant, the optimal desulfurization rate of 35.11 % and oil recovery of 95 % were obtained at...
متن کاملNew Sorbents for Desulfurization of Diesel Fuels via -Complexation
Desulfurization of a commercial diesel fuel by different adsorbents was studied in a fixed-bed adsorber operated at ambient temperature and pressure. In general, the adsorbents tested for total sulfur adsorption capacity at breakthrough followed the order: AC/Cu(I)-Y Cu(I)-Y Selexsorb CDX (alumina) CuCl/ -Al2O3 activated carbon Cu(I)-ZSM-5. The best adsorbent, AC/Cu(I)-Y (layered bed of 15 wt %...
متن کاملPolyVinylPolyPyrrolidone-Supported Boron Trifluoride (PVPP-BF3); Highly Efficient Catalyst for Oxidation of Aldehydes to Carboxylic Acids and Esters by H2O2
A highly efficient method for the oxidation of aldehydes to carboxylic acids using PolyVinylPolyPyrrolidone supported - Boron Trifluoride (PVPP-BF3) in the presence of 35% hydrogen peroxide has been developed in acetonitrile at 60 °C. This procedure cleanly oxidizes variety of aldehydes to the corresponding carboxylic acids. Oxidative esterification of benzaldeh...
