|Abstract:||Vacuum residue is crude oil fraction obtained at the bottom of vacuum distillation column having boiling point above 565°C. Vacuum residue is often used without further treatment as fuel oil or for the production of asphalt. Ozone <span class="pct-rti">(O<sub>3</sub>) is a triatomic allotrope of oxygen and is an extremely strong oxidizing agent. It can cleave and oxidize benzene and other aromatic structures including PAHs. Nitrous oxide is also a good oxidizing agent relate to a particular state of anion radical oxygen species O<sub>α</sub><sup>-</sup> (called α-oxygen), which forms on α-sites from N<sub>2</sub>O. Liquid phase oxidation of vacuum residue at temperature 100-150°C either ozone or nitrous oxide results into conversion of the residue to oxygenated hydrocarbons. This process reduces concentration of aromatics and olefins which are known to be coke precursors in reforming application. The reaction of oxidant with vacuum residue has been investigated in detail using FTIR. </span>|
