MANUFACTURING METHOD OF W-CONTAINING OXIDATIVE DESULFURIZATION CATALYST

摘要

The present invention relates to a tungsten-containing selective and oxidative desulfurization catalyst, more specifically to a selective and oxidative desulfurization catalyst obtained by making Keggin structure heteropoly acid including tungsten in the structure react with ammonium salt. The selective and oxidative desulfurization catalyst of the present invention has strong chemical affinity against petroleum-based sulfur compounds and has high desulfurization activity for transforming the non-degradable petroleum-based sulfur compounds into sulfone compounds using selective partial oxidation reaction, and removing the non-degradable petroleum-based sulfur compounds.
