Claim:
1. An apparatus for conversion of sulfur-containing and nitrogen-containing hydrocarbon compounds in a hydrocarbon feedstock to their respective oxidation products comprising: a feed separation apparatus operable to separate the hydrocarbon feedstock into a first portion and a second portion and including an inlet for receiving the hydrocarbon feedstock, a first portion outlet and a second portion outlet; an aromatic separation apparatus being in fluid communication with the second portion outlet of the feed separation apparatus for passage of the second portion of the hydrocarbon feed and operable to extract aromatic compounds from the second portion of the hydrocarbon feed, the aromatic separation zone including an inlet for receiving the hydrocarbon feedstock, an aromatic-rich outlet and an aromatic-lean outlet; an organic peroxide generation apparatus in fluid communication with the aromatic-rich outlet and a-source of gaseous oxidant and having an outlet for discharging a mixture containing organic peroxide and heteroatom-containing hydrocarbons, the organic peroxide generation apparatus containing an effective quantity of catalyst effective to promote organic peroxide generation and operating under conditions effective to promote organic peroxide production by reaction of hydrocarbons in the aromatic-rich fraction and gaseous oxidant; a hydrotreating apparatus in fluid communication with the aromatic-lean outlet and having a treated product outlet; and an oxidative reaction apparatus in fluid communication with the organic peroxide generation apparatus outlet and the first portion outlet of the feed separation apparatus for passage of the first portion of the hydrocarbon feed, and having an outlet for discharging a mixture containing oxidation products of heteroatom-containing hydrocarbons, the oxidative reaction apparatus operating under conditions effective to promote oxidation of heteroatom-containing hydrocarbons by reaction of heteroatom-containing hydrocarbons and the produced organic peroxide.
