Definitions

  • the invention relates to a method for producing a gasoline fuel, in which coal-derived light oil is treated in a refining stage and a subsequent reforming stage.
  • gasoline fuels obtained from coal are highly aromatic because of the molecular structure of the coal from condensed aromatics and have a relatively high benzene content, namely between 10 and 20% by weight.
  • This high benzene content is undesirable because of the toxic properties of benzene.
  • the object of the invention is to create a method of the type mentioned at the beginning with which a low-benzene, high-octane, environmentally friendly gasoline fuel is obtained which preferably has octane numbers (RON / MOZ) of at least 98/88 without the addition of octane-increasing additives; this process should therefore work regardless of the availability of low-benzene admixing components.
  • a core fraction with the relatively highest benzene content is distilled from the reformate (insert reformate) in a process of the type mentioned above, that the other two reformate fractions are combined and used together as gasoline fuel, and that this gasoline fuel has a benzene content of at most 5% by weight.
  • the gasoline according to the invention has a benzene content which is basically as low as possible, but preferably at most 5% by weight, so that corresponding official requirements for the benzene content can be met without difficulty.
  • a fraction highly enriched with benzene is obtained which, owing to its high benzene concentration, can also be used as a valuable chemical raw material from an economic point of view. This also produces paraffins and naphthenes in high concentrations, which can be used as solvents or as an insert for olefin production by known processes.
  • the refined gasoline has relatively low octane numbers and does not meet the RON / MOZ of 98/88 required by DIN 51 600.
  • Reforms are needed to improve the octane number.
  • the isomerization-aromatization reaction is predominant in the reformer.
  • the naphthenes, cyclohexane and methylcyclopentane form benzene in the reformer.
  • the benzene content in the coal gasoline is between 10 and 20% by weight.
  • the use reformate has a boiling point of 40 to 200 ° C. and an octane number RON or MOZ of 98 or 88.
  • the preferred bonds for hydrotreating result from the journal "Petroleum and coal-natural gas petrochemicals combined with fuel chemistry", vol. 36, 1983, pages 370 to 372.
  • the boiling point of the core fraction to be distilled from the reformate is about 65 to 85 ° C.
  • a reformate of coal origin (stream 1 according to the attached process scheme) is broken down into three fractions by rectification (streams 2, 3 and 4).
  • Stream 2 consists of low-boiling hydrocarbons which, depending on the separation efficiency and the mode of operation of the rectification column, receive fluctuating benzene fractions, but generally less than 5%.
  • Stream 3 is a fraction in which benzene is enriched and contains the accompanying hydrocarbons of benzene specific to coal oil.
  • Stream 4 contains the higher-boiling hydrocarbons of the feed reformate and, depending on the separation efficiency and driving style of the rectification column, fluctuating benzene parts, generally less than 5%.
  • Stream 5 a combination of streams 2 and 4, represents the low-benzene gasoline with less than 5% benzene content.
  • the usual packed columns or bubble-cap trays can be used for rectification.
  • the boiling cut of stream 3 must be such that a benzene content of ⁇ 5% by weight is ultimately obtained in stream 5.
