The hydrocracking of gasoline fractions

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

Conclusions

  1. 1.

    It has been shown that by hydrocracking gasoline fractions from Arlansk crude it is possible to obtain from the catalyzate fraction up to 30–35 wt.% of a light isocomponent, which boils up to 85°C and has an octane number of 84 by the motor method.

  2. 2.

    Compared with platinum and palladium catalysts a nickel catalyst is more effective, because it enables an isocomponent with an appreciably higher content of isoparaffinic hydrocarbons to be obtained.

  3. 3.

    To achieve the most favorable results heavy gasoline fractions (140–180 or 140–200°C) should be subjected to hydrocracking, using a moderate conversion (40–50%) and relatively low temperatures (300–350°C).

  4. 4.

    In contrast to the initial feedstock, the residual part of the hydrocracking catalyzate (the fraction above 85°C) contains more aromatic and naphthenic hydrocarbons and is a better feedstock for catalytic reforming.
