Definitions

  • the invention relates to the catalytic reforming under elevated pressure and temperature of gasoline of the type specified in the preamble of claim 1.
  • Catalytic reforming is one of the most important processes for the production of gasoline fuels, which, in terms of their knock resistance, have to meet the increasing requirements in the increasingly powerful internal combustion engines.
  • the octane number for n-heptane is 0, that of iso-octane 100.
  • Octane numbers of more than 100 are achieved by adding lead tetraethyl to iso-octane.
  • noble metal catalysts such as platinum, possibly along with other metals such as rhenium, on high-purity alumina (Al 2 O 3 ) are used as supports.
  • the temperatures used are approximately 480-550 ° C. and the pressures approximately 8-30 bar, a high hydrogen partial pressure counteracting the inactivation of the catalyst by coke formation on the catalyst support. Lower pressures favor higher yields of reformate.
  • Typical conditions when operating a reformer are given, for example, in Hydrocarbon Processing, Sept. 1980, p. 162.
  • the adequate activity of the catalyst is maintained by suitable processes for regenerating the catalyst, for example by burning off the carbon on the catalyst in so-called swing reactors, but also by continuously discharging part of the catalyst from the fluidized catalyst bed maintained in the reformer.
  • the net hydrogen production that occurs in the reforming is an important source for covering the hydrogen demand existing in a refinery for various refining processes and other conversion processes.
  • the mixtures of carbon-based reformer feed product with reformer feed specification and mineral oil-derived reformer feed product are preferably used in a weight ratio of 20 to 80 to 40 to 60.
  • a typical petroleum-derived gasoline as a reformer feed consists for example of 44% by weight of paraffins, 41% by weight of monocycloparaffins, 2% by weight of dicycloparaffins and 13% of aromatics.
  • the carbon-based light oils or petrol from the liquefied hydrogenation of a gas flame coal of the Ruhr area according to the specified process of hydrogenation in the sump and gas phase, added as a reformer feed product, differ from the mineral oil-derived reformer feed products mainly by a lower content of paraffins and a higher content of monocycloparaffins.
  • ground coal In a sump phase hydrogenation at elevated pressure and temperature, ground coal, if appropriate with the addition of catalytically active substances, is mixed with a mashing oil mixed with gaseous hydrogen, the residue is discharged from the effluent from the sump phase hydrogenation, the residue-free volatile products are cooled, optionally separated from a fraction serving as mashing oil, subjected to gas phase hydrogenation on a Ni / Mo or Co / Mo catalyst applied to a support material made of A1 2 0 3 or A1 2 0 3 -Si0 2 and a refined carbon-derived naphtha or gasoline fraction won that as such or after
  • the catalyst service lives which are characterized by a predetermined activity of the platinum catalyst applied, for example, to a support material made of Al 2 O 3 , are also favorably influenced.
  • FIGS. 1 and 2 of the drawing in which the motor octane number (MOZ) and the research octane number (RON) are plotted on the ordinate and the C 5+ yield in% by weight are plotted on the abscissa
  • the improvements in C 5+ yield and octane number achieved for different mixtures of reformer feed products can be read off immediately.
  • the three curves in FIG. 1, seen from bottom to top, correspond to a commonly used petroleum-derived petrol (as a comparative example) and a mixture of a mixture of such petrol and a coal-based reformer feed in a weight ratio of 80:20 or in a weight ratio of 60:40 Reformer feed product.
