The removal of sulfur compounds from hydrocarbon-based distillate fuels is essential due to environmental concerns (i.e., acid rain and airborne particulate material production), and because a few parts per million of sulfur are enough to poison the catalysts used for the purification of the exhaust gases of diesel cars. The oxidation of dibenzothiophene (DBT) by H2O2 at 333 K was investigated using the catalysts (hydrotalcite (HT) and MgLa mixed oxide) and solvents (methanol, acetonitrile, benzonitrile, acrylonitrile, and 3-methoxypropionitrile). High activity was found only after calcinations followed by rehydration of HT. Acetonitrile was the best solvent, while much lower reaction rates were observed in methanol. The decomposition of H2O2 into oxygen was observed for HT, and was the major reaction at > 353 K. This reaction did not occur in the absence of nitrile, and was faster over MgLa mixed oxide of higher basic strength. The activity increased with increasing Mg/Al ratio due to a lower rate of H2O2 decomposition attributed to a lower basicity of the solid.
