Characters of the Diesel-Like Fraction from Sludge Pyrolysis Oil

Abstract:

Sludge pyrolysis oil has the potential to substitute for refinery petroleum products for its similar characters with petroleum. In this study, the diesel-like fraction, with high heating value and low sulfur content compared with sludge pyrolysis oil, was obtained from sludge pyrolysis oil which was processed by two-step distillation to remove volatile component and compounds with high boiling points. The chemical composition of diesel-like fraction was investigated by Gas Chromatograph / Mass Spectrometer. The results indicated that this part comprises compounds containing N and O element 48.3% and hydrocarbons 51.7%, the hydrocarbon chain length of the alkanes and alkenes distributes across the C10~C20 mass range in the latter which was close to that of diesel. The sulfur content of diesel-like fraction is 10 times higher than that of diesel, and other fuel characters were similar with that of diesel, which indicated that diesel-like fraction was promising to substitute for diesel. After adding 10% diesel-like fraction into 5 # diesel, the fuel characters of diesel changed so little that it did not influence the application of diesel, which would be significant to alleviate the shortage of petroleum.
