THE EFFECT OF TEMPERATURE ON PYROLYSIS OF ASPHALTENES

In this study,pyrolysis experiments have been performed at different temperatures to onvestigate the possible effects of temperature on the recovery of the biomarkers from biodegraded oils.The results showed that the yield of the dichlormethane estracts is maximum at 340℃.In addition,pyrolysis temperatures lower than 300℃ have little effevt on the distribution of the biomarkers in the pyrolysates of asphaltenes.So 300℃ is a relatively suitable asphaltene pyrolysis temperature for oil/oil correlation.
