The present invention relates to a method of converting mercaptans contained in gaseous and/or liquid hydrocarbon cuts into disulfides by contacting in the absence of gaseous or liquid oxygen or provided by a peroxide on a solid comprising an amorphous or crystalline oxide and one or more elements of group IA of the Periodic Table and/or one of more elements of group IIA of the Periodic Table. La présente invention se rapporte à un procédé de transformation en disulfure des mercaptans contenus dans des coupes hydrocarbures gazeuses et/ou liquide par mise en contact en absence d'oxygène gazeux ou liquide ou apporté par un peroxyde sur un solide comprenant un oxyde amorphe ou cristallisé et un ou plusieurs éléments du groupe IA du tableau périodique et/ou un ou plusieurs éléments du groupe IIA du tableau périodique.
