Catalysts amenable to oxidizing sulfur compounds and systems and methods of using these catalysts to effect the removal of sulfur from crude oil and crude oil distillates are disclosed. The catalyst is disposed with a titanyl moiety which serves to selectively coordinate sulfur compounds and affect their oxidation. The titanyl may be bound within a polymer or on the surface of a polymer or on the surface or in the pores of an inorganic support. The resulting oxidized sulfur compounds are readily sepa-rated from the initial crude oil or crude oil distillate streams by traditional separation techniques arrayed as described in the sys-tems and methods disclosed.

La présente invention concerne des catalyseurs permettant loxydation de composés de soufre et des systèmes et des procédés permettant dutiliser ces catalyseurs pour effectuer lélimination du soufre du pétrole brut et des distillats de pétrole brut. Le catalyseur est placé avec une fraction de titanyle qui sert à coordonner sélectivement les composés de soufre et à influencer leur oxydation. Le titanyle peut être lié au sein dun polymère ou à la surface dun polymère ou à la surface ou dans les pores dun support inorganique. Les composés de soufre oxydés obtenus sont faciles à séparer du pétrole brut initial ou des flux de distillats de pétrole brut par des techniques de séparation décrites dans les systèmes et procédés présentés.
