Notes:
Oil shales are one of the alternative sources of hydrocarbon fuels (“syntheticpetroleum”), characterized by the increased sulfur and nitrogen content which represent evengreater ecological problem in use, compared to classical fuels.Acidithiobacillus ferrooxidans is capable of oxidizing pyrite to iron (III)-ion, providing a strongoxidation agent at low pH. We have used this oxidizing agent for oxidation of sulfur present in DBTas a substrate model to demonstrate its potential to oxidize organically bound sulfur in oil shales.An HCl-concentrate was used as the hydrocarbon matrix. Acidithiobacillus ferrooxidans is alreadyrecognized to oxidize the pyritic sulfur component, thereby potentially providing a complete sulfurremoval system.By applying GC-MS we established that DBT transformation occurred by oxidation orelimination of sulfur. The products obtained are more soluble in water than parent compounds andthis reduces concentration of organic sulfur
