Abstract

Catalysts containing tungsten oxide, molybdenum oxide, and SBA-15 aluminosilicate were studied for the oxidation of a model dibenzothiophene (DBT) mixture with high sulfur content and a diesel fraction. Low-temperature nitrogen adsorption–desorption, transmission electron microscopy (TEM), nuclear magnetic resonance (NMR), infrared (IR) spectroscopy, and temperature-programmed desorption of ammonia were used to analyze the catalysts. Conditions were selected for the oxidation of the model mixture, which simulates the composition of real fuel, and for the oxidation of the diesel fraction.
