Deoxydesulfurization of liquid fuels using air assisted performic acid oxidation followed by reductive decomposition through in situgenerated Ni-boride

The deoxydesulfurization of organosulfur compounds in model and commercial oil was investigated by oxidation with performic acid followed by reduction with in situgenerated Ni sub(2)B under ambient conditions. The desulfurization efficiency of the process is high and is superior to the extractive ODS, since it does not require a large quantity of solvent for the extraction and also the parent hydrocarbons of the organosulfur compounds are returned to the feed, thereby avoiding loss of oil.
