desulfurization study of gas oil is very important, in
order to reduce the resulted pollution from acidic gas SO2, which
results by burning the fuel, and to prevent poisoning of sensitive
catalysts with sulfur, in subsequent processes, and to prev
ent
corrosion of engines and equipment in refineries. So, refineries
have been restricted by very low sulfur content, in their products.
Because the hydrodesulphurization did not demonstrate good
efficiency in reducing the sulfur and aromatics content to the
required limits, it has been to search for alternative or completed
methods for it .One of these processes is the oxidation –extraction
method, which has been studied in our work. We used hydrogen
peroxide as oxidant, and acetonitrile as extraction solvent. We
studied Operation conditions in terms the proportion of oxidant and
extraction solvent to fuel, and we chose the operation temperatures
to suit the specifications of the oxidant and extraction solvent. We
studied diesel specifications, which we applied at it the process of
oxidation and extraction.
