Hydrocarbon composition of fractions obtained by thermal diffusion of the isoparaffin-naphthene portion of Korobkov gas oil distillate

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

Conclusions

  1. 1.

    Thermal diffusion fractions of the isoparaffin-naphthene portion of the gas oil distillate from Korobkov crude were investigated by infrared and mass spectrometry.

  2. 2.

    The refractive index and density of thermal diffusion fractions differ sharply for each 50°-cut, but the molecular weights are similar.

  3. 3.

    An increase in the degree of condensation of naphthenic structures and a decrease in isoparaffinic hydrocarbon content is observed with progressing thermal diffusion fraction number.

  4. 4.

    Mono- and dicyclic hydrocarbons constitute the main bulk of naphthenic structures.

  5. 5.

    The longest chains of the type R-(CH2)n-CH3 belong most probably to isoparaffinic structures.

  6. 6.

    The prevalence of sixmembered rings over fivemembered rings is observed in the investigated fractions of Korobkov crude.
