Abstract

A találmány tárgya eljárás telítetlen szénhidrogének gázfázisúoxidálására alkalmas, titán-dioxid vagy titán-oxid-hidrát-alapú,aranyszemcsékkel bevont hordozós katalizátor regenerálására oly módon,hogy a katalizátort vízzel vagy hígított savval vagy hígított hidro-peroxid oldattal érintkeztetve, katalitikus aktivitásábanregenerálják. ÓThe subject of the invention is a method for regenerating a titanium dioxide or titanium oxide hydrate-based catalyst coated with gold particles suitable for gas-phase oxidation of unsaturated hydrocarbons in such a way that the catalytic activity of the catalyst is regenerated by contacting it with water or diluted acid or a diluted hydroperoxide solution.
