Production of aromatic hydrocarbons from kerosine-gas oil fractions from sulfur crudes

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

Summary

  1. 1.

    A flowsheet is proposed for the processing of kerosine-gas oil fractions from high-sulfur petroleums, which provides for the possibility of producing various chemical and fuel products by solvent extraction and hydrogenation.

  2. 2.

    It is shown that aromatized fractions which are suitable for the production of aromatic hydrocarbons by hydrogenation, as well as low-sulfur components for Diesel fuel, may be obtained from kerosine-gas oil fractions by extraction with selective solvents.

  3. 3.

    By hydrorefining extracts under a hydrogen pressure of 40 atm the feedstock is extensively desulfurized and the bicyclic aromatic hydrocarbons are partially hydrogenated, this being accompanied by the formation of low-boiling fractions and a lowering of the boiling point of the liquid products.

  4. 4.

    By the high-temperature hydrogenation of the hydrorefined extracts, monocyclic aromatic C6–C10 hydrocarbons, naphthalene and other hydrocarbons are produced, the relative content of individual hydrocarbons and their concentrations in narrow hydrogenate fractions being controllable by varying the extent of the hydrodealkylation reaction and the decomposition of the standard hydrocarbons.
