Abstract
An oxidative treatment process, e.g., oxidative desulfurization or denitrification, is provided in which the oxidant is produced in-situ using an aromatic-rich portion of the original liquid hydrocarbon feedstock. The process reduces or replaces the need for the separate introduction of liquid oxidants such as hydrogen peroxide, organic peroxide and organic hydroperoxide in an oxidative treatment process.
Claims30
A process for conversion of heteroatom-containing compounds in a hydrocarbon feedstock to their oxidation products comprising:
- separating the hydrocarbon feedstock into an aromatic-lean fraction and an aromatic-rich fraction;
- contacting the aromatic-rich fraction with an effective amount of gaseous oxidant under conditions effective for organic peroxide generation and to produce a mixture containing organic peroxide and heteroatom-containing hydrocarbons;
- contacting the mixture containing produced organic peroxide and heteroatom-containing hydrocarbons with the aromatic-lean fraction under conditions effective for oxidative conversion of heteroatom-containing hydrocarbons in the mixture and in the aromatic-lean fraction into oxidation products of heteroatom-containing hydrocarbons.
