Microbiological stability of petroleum oils

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    The microbiological stability of petroleum oils depends on their hydrocarbon composition; oils from highly aromatic petroleums prove to be the most stable.

  2. 2.

    Polycyclic (heavy) aromatic hydrocarbons play a basic role in microbiological stability.

  3. 3.

    The microbiological susceptibility of petroleum hydrocarbons, plus certain nitrogenous and sulfur-containing compounds, has been studied.

  4. 4.

    It has been established that n-alkanes are least stable to attack by microorganisms; the most stable are aromatic compounds of the benzene series.

  5. 5.

    It is necessary to take into account differences in stability of hydrocarbons toward microbiological damage in manufacturing petroleum products for use in tropical latitudes, choosing correctly the original raw material and the extent of product refining.
