Definitions

  • the invention relates to a gasoline fuel and a method for producing the same, in which a purified or refined light coal oil with a boiling range of about 60 to 185 * C is subjected to catalytic reforming.
  • coal-derived light oil, medium oil and heavy oil are obtained in addition to asphalt-containing fractions and cracked gas.
  • fractions obtained as an oil gain and subjected to further processing are reacted with further hydrogen, the hydrogenation being carried out in the gas phase.
  • the light coal oils obtained by the splitting hydrogenation of coal and by subsequent refining and hydrocracking must be subjected to catalytic reforming in order to achieve the specifications as gasoline for gasoline engines. Refining carefully cleans the sulfur, nitrogen or oxygen-containing hetero compounds to maintain the effectiveness of the catalyst.
  • a high benzene content in the reformate gasoline obtained from light coal oil is favorable for a high octane number and thus a high knock resistance of petrol
  • the task is derived from this to provide a low-benzene reformate gasoline from light coal oil, which fulfills the specifications of a super gasoline for petrol engines in all characteristic values.
  • the solution to this problem is that the reformer feed stream based on a purified or refined light coal oil is divided by distillation into a fraction boiling above about 85 ° C, which is catalytically reformed, and into a fraction boiling up to about 85 ° C, with the obtained reformate is combined.
  • the fraction boiling up to about 85 "C has a low benzene content and a relatively high cyclohexane content. It also has a low density, which means that after combination with the reformate obtained, the specification of the density range for super gasoline is easily achieved.
  • Above about 85 ° C boiling fraction Subject in the usual way to catalytic reforming, in particular naphthenes being dehydrated to aromatics, paraffins or naphthenes isomerized and paraffins being dehydrocyclized with elimination of hydrogen. Through hydrocracking, longer hydrocarbon chains are split into hydrocarbons of shorter chain length, whereby shorter-chain paraffins are formed as a result of hydrogen addition to the resulting olefinic fragments. These reactions result in a net production of split off hydrogen and of C 1 to C 4 hydrocarbon compounds. The reactions taking place side by side during the reforming all lead to an increase in the knock resistance of the reformate gasoline obtained.
  • the invention is based on the idea of cutting off the fraction boiling up to about 85 ° C. from the reformer feed by distillation and adding it to the reformate bypassing the reformer.
  • the relatively high cyclohexane content of this fraction which boils up to about 85 ° C., would lead to a strong increase in the benzene content in the reformate due to dehydrogenation in the reformer.
  • the reformer feed stream is divided in an atmospheric distillation.
  • the benzene content of the reformate obtained can be limited to a value of at most about 5% by weight by means of suitable process control, as a result of which super fuel according to DIN 51 600 can be produced without blending with other components or admixing to reformate gasoline derived from mineral oil.
  • Stream 3 has the following properties: benzene content 10.3% by weight; Density at 15 ° C 0.741 g / ml; Research octane number (RON) / motor octane number (MOZ) 78.9 / 75.9. Stream 3 is passed around the reformer without further treatment.
