METHOD FOR DESULPHURIZING THIOPENE DERIVATIVES CONTAINED IN FUELS |
摘要 |
The invention concerns a method for selectively desulphurizing thiopene compounds contained in hydrocarbons derived from crude oil distillation, whether refined or not, which consists in oxidising the thiophene sulphur atoms into sulphone in the presence of an oxidising agent and in separating said sulphonated compounds from said hydrocarbons. The invention is characterised in that it consists in oxidising the thiophene compounds in a two-phase turbulent medium comprising a hydrocarbon phase and an aqueous phase, in the presence of at least an oxidising agent soluble in at least one of the two phases and of at least a metal catalyst in soluble or dispersed form in a liquid or in solid form, separation and oxidation occurring simultaneously.
