| 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 (O3) 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 Oα- (called α-oxygen), which forms on
α-sites from N2O. 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.
