Definitions

  • the invention relates to a method for desulfurizing a motor fuel on board a motor vehicle.
  • Motor fuel is usually desulphurized using large chemical processes in refineries to produce the fuel.
  • Known processes for this are extraction, adsorption (e.g. US 5,360,536), distillation or microbiological processes.
  • the commercial motor fuels in Europe currently have a residual sulfur content of approx. 200 ppm. This is problematic with regard to the sulfur compatibility of modern exhaust gas aftertreatment systems that contain adsorbers and catalysts. Residual sulfur contents of less than 10 ppm should therefore be aimed for.
  • the object of the invention is to provide a method for separating sulfur-containing components from an engine fuel that is suitable for use in mobile systems.
  • only a small construction volume and a low weight should be required for its implementation.
  • the fuel is desulfurized on board the motor vehicle by selective separation of the sulfur-containing fuel components by means of liquid phase adsorption.
  • An adsorption material is used that selectively only adsorbs the sulfur-containing fuel components.
  • solids with a high surface area are used as adsorbents, especially those substances which contain Al, Mg, Si or Ti in oxidic form. Examples include Al 2 0 3 , MgO, Si0 2 , Ti0 2 , zeolites, hydrotalcites or mixed oxides.
  • a metal such as, for example, an alkali metal, an alkaline earth metal, a rare earth metal, or Ag, Cu, Co, Fe, Mn, Ni, V or Zn can also be used.
  • Biogenic materials such as, for example, enzymes can also be used.
  • the sulfur contained in the fuel can be converted into other sulfur compounds by microorganisms that are brought into contact with the fuel.
  • the adsorption material has a temporary separation performance and must be replaced after some time within the maintenance intervals of the vehicle.
  • the adsorption material can also be regenerated on board the motor vehicle, in particular by thermal treatment.
  • the regeneration can advantageously be carried out by thermostatting using the coolant circuit in the vehicle (approx. 80 ° C) or the engine oil circuit (> 100 ° C).
  • the adsorption device and fuel filter can be integrated in one structural unit.
  • Adsorption material and the material for fuel filtering can, for example, be arranged or layered directly next to or on top of one another.
  • the low-sulfur fuel is particularly suitable for adding to a lean-burn gasoline engine.
  • the addition of low-sulfur diesel fuel can reduce the particle emissions in the exhaust gas.
  • the low-sulfur fuel can also be used as a reducing agent for denitrification catalysts in lean exhaust gas.
  • Another application of the low-sulfur fuel obtained with the method according to the invention is for the desulfation of a catalyst in an exhaust gas aftertreatment system of an engine.
  • sulfur accumulates on the surface of the catalytic converter from time to time, which is removed by regeneration (desorption). This can only be done with low sulfur exhaust gas.
  • the equipment required to carry out the method according to the invention is low. As a result, the construction volume and weight can also be kept small.
  • the method according to the invention is therefore suitable for use in all mobile systems such as passenger or commercial vehicles or in rail-bound vehicles.
  • Another advantage of the method according to the invention is that the low-sulfur fuel fraction is available on board immediately when the engine is started. An additional storage tank for low-sulfur fuel especially for the cold start phase can therefore be dispensed with.
  • the low-sulfur fuel obtained can either be used directly or stored in a storage container.
  • the method according to the invention can be used for all motor fuels, in particular petrol or diesel fuels, kerosene or methanol.
  • Fig. 1 shows a first structure for performing the method according to the invention
  • 2 shows a second structure for carrying out the method according to the invention
  • Fig. 3 shows an adsorption device for performing the invention
  • Fig. 4 shows an experimental setup for determining the adsorber properties and adsorber capacity
  • Fig. 5 shows the effect of the fuel sulfur content on the NO x conversion
  • the adsorption device can be connected in series (Fig. 1) or as a bypass to the normal fuel supply (Fig. 2) after the fuel pump.
  • FIG. 1 An arrangement with a series connection of fuel pump and adsorption device is shown in FIG. 1.
  • the fuel is removed from the fuel tank KT by means of an electric fuel pump KP, then passes through the adsorption device AD according to the invention before it is fed to the engine via the injection nozzle ED.
  • the intake pipe of the engine is labeled AR.
  • all fuel supplied to the engine is desulfurized.
  • a valve V can be used to switch between the normal branch without an adsorption device and the branch with an adsorption device. This makes it possible to use desulfurization only in certain operating phases of the engine. For example, desulphurization can only be activated when the engine is lean and when the adsorber catalyst contained in the exhaust gas aftertreatment system is desulfated.
  • the bypass circuit shown can increase the mileage of the adsorption device or make it smaller.
  • FIG. 3 shows a schematic representation of an adsorption device in the form of a separation column, the interior of which is filled with the adsorption material.
  • the sulfur-containing fuel mixture to be separated is added undiluted to the entrance of the separation column and to the adsorption material.
  • the sulfur-containing fuel components are selectively adsorbed on the adsorption material.
  • the non-adsorbed, sulfur-free, (generally low-boiling) fuel components leave the separation column as an eluate at the opposite end.
  • the separation is surrounded by an annular channel through which a heat transfer medium flows to temper the separation column.
  • the fuel is taken from a storage vessel and fed through the thermostated adsorption column via an HPLC pump (max. Throughput 10 ml / min).
  • HPLC pump max. Throughput 10 ml / min.
  • the eluate can be examined offline using a gas chromatograph and X-ray fluorescence analysis.
