- step d) comprises one of the following processes:
- methanol-to-gasoline (MTG) process for converting the methanol (12) into a fuel
- a methanol-to-dimethyl ether (MTL) process to convert the methanol to dimethyl ether as a fuel.
- Dimethyl ether can be burned in the diesel engine because of its cetane number, which is usually in the range of 55 to 60, and thus can be used as a diesel fuel, without any structural changes to the engine itself are necessary.
- the at least one fuel which is provided in step d) comprises at least one of the following substances:
- LPG Liquefied Petrol Gas, LPG
- SNG Natural Gas Substitute
- Benzene fuel is understood to mean in particular an Otto fuel.
- gasoline fuel in this context refers to a fuel with which an internal combustion engine can be operated, for example an Otto fuel with a corresponding knock resistance.
- LPG and petrol are already being sold practically everywhere in Germany as fuels for the operation of gasoline engines.
- Natural gas substitute can be used as fuel as a substitute for so-called CNG also compressed natural gas (compressed natural gas).
- CNG compressed natural gas
- Diesel fuel is understood as meaning a fuel with which a diesel engine can be operated; in particular, a diesel fuel comprises at least partially methyl ether.
- the flue gas of a power plant is used in step a).
- the flue gas of a coal power plant preferably a lignite and / or hard coal power plant, an oil power plant and / or a gas power plant can be used.
- the flue gas is subjected before step c) a carbon dioxide scrubbing.
- this is understood to mean a MDEA process or absorption with a polyethylene glycol dimethyl ether, in particular with a product commercially available under the name Genosorb 1753.
- the MDEA process is understood to mean a carbon dioxide scrubbing with methyldiethanolamine, which is preferably carried out in a temperature range from 75.degree. C. to 85.degree.
- the methyldiethanolamine solution shows even at low carbon dioxide partial pressures a high loading of carbon dioxide, which can be degassed by relaxing to atmospheric pressure, a large part of the carbon dioxide.
- Genosorb process is understood to mean carbon dioxide scrubbing with a polyethyleneglycol dimethyl ether, in particular with a substance sold under the name Genosorb 1753.
- the good gas solubility of acid gases such as carbon dioxide and hydrogen sulfide is advantageous in the leaching of carbon dioxide from flue gases.
- By the carbon dioxide laundry an impurity content of 2% by volume and less in carbon dioxide is achieved.
- step b) hydrogen is provided in step b) from the electrolysis of water.
- electrical energy is preferably used in the electrolysis as electrical energy, which is obtained from a process in which substantially no carbon dioxide is produced. This further improves the overall CO2 balance of the process. This is how sustainable carbon dioxide can be converted into fuel.
- the selection of the various alternatives A) to D) can be carried out depending on the circumstances.
- In the conversion of solar energy into electrical energy according to alternative D) can be used in particular photovoltaic electricity generated.
- electric power can be used, which is generated by the sun-driven evaporation of water with subsequent operation of a steam turbine.
- electric current in particular electric current can be used, which was obtained by wind energy through wind turbines.
- mechanical energy into electrical energy based on flowing water according to C2 can be used in particular on hydroelectric power plants or tidal power plants.
- This embodiment of the method according to the invention leads to a positive carbon dioxide balance. So effectively sustainable carbon dioxide can be converted into fuels. This can be used to operate internal combustion engines and in particular to secure individual personal mobility.
- the method according to the invention for temporary storage of energy can thus be used in which methanol or a fuel obtained in step d) is used as the chemical storage of the energy. This is particularly advantageous if a variable available electricity supply, for example in tidal or wind power plants.
- the fuel prepared by the process according to the invention and / or the methanol can be used as a chemical storage for an oversupply of, for example, wind or Ge time energy.
- the resulting methanol or the resulting fuel in particular gasoline or diesel fuel, to generate electricity when there is a supply of electricity.
- This can be done by a corresponding internal combustion engine, in particular with catalytic exhaust gas purification, which drives a corresponding generator.
- This allows the use of the method according to the invention for intermediate storage of energy, which will become increasingly important in the increased use of renewable energies. This represents a sensible way of storing carbon dioxide from the flue gas of fossil-fueled power plants.
- Fig. 2 shows a second embodiment of the method according to the invention in the flow chart and
- FIG. 3 shows a third embodiment of the method according to the invention in the flow chart.
- a fossil fuel 2 preferably coal
- an oxygen-containing gas 3 preferably air
- the resulting flue gas 4 is fed to a carbon dioxide scrubber 5.
- an amine or carbonate wash is preferably carried out. This results in a substantially pure carbon dioxide 6 and a corresponding scrubber exhaust gas 7.
- the carbon dioxide 6 is fed to a methanol synthesis 8.
- water 9 is supplied to an electrolysis 10. This is obtained with electrical energy from in particular so-called regenerative energy, such as solar, wind, and / or water energy operated. As product of the electrolysis 10, hydrogen 11 is obtained, which is likewise fed to the methanol synthesis 8.
- methanol synthesis process 8 preference is given to using a low-pressure methanol synthesis process which is carried out at a pressure of about 50 bar to about 100 bar at temperatures between about 200 and about 300 ° C.
- the methanol synthesis process 8 is assisted by a corresponding catalyst.
- a corresponding catalyst For example. are used as catalysts copper-zinc oxide Alummina catalysts. Basically, carbon dioxide is converted with hydrogen to methanol and water. The resulting water can in this case be supplied to the electrolysis 10 as water 9 again.
- a high-pressure methanol synthesis process can be used, which is carried out at pressures of about 250 to 350 bar and temperatures of 360 to 380 ° C.
- a medium pressure method can be used, which operates at an operating pressure of about 100 to about 250 bar in a temperature range of about 220 to about 300 ° C.
- the methanol 12 produced in the methanol synthesis 8 is then fed to a "methanol-to-gasoline" (MTG) process 13.
- MTG methanol-to-gasoline
- an aromatic-rich hydrocarbon mixture is formed on zeolites from methanol
- the MTG process 13 usually provides three products are gasoline fuel 14, LPG 15 and Erdgassubstitut 16.
- the relative proportions of the products 14, 15, 16 result from the process parameters under which the MTG process 13 is performed. For example, can be obtained from 100 tons of methanol 39 tons of gasoline fuel 14, 3 tons of LPG 15 and 2 tons Erdgassubstitut 16, which still generates 56 tons of water.
- gasoline fuel 14 is meant a mixture of hydrocarbons, which is usually sold as gasoline fuel with different anti-knock properties.

- FIG. 2 schematically shows a second embodiment variant of the method according to the invention. Identical elements are here provided with the same reference numerals as in FIG. For the sake of clarity, only the differences from the embodiment variant in FIG. 1 will be explained; for the remainder, reference is made to the description of FIG. 1.
- the methanol 12 formed in the methanol synthesis 8 is fed in this embodiment to a "methanol-to-dimethyl ether" (MTL) process 17, in which the methanol 12 is catalytically converted to wholly methylene 18.
- MTL methanol-to-dimethyl ether
- the resulting methyl ether 18 can be used as Substitut be used for conventional diesel fuels.
- Fig. 3 shows schematically a third embodiment of the method according to the invention. Identical elements are here provided with the same reference numerals as in FIG. It is for the sake of clarity only the differences from the embodiment in Fig. 1 will be explained, for the rest, reference is made to the description of FIG. 1.
- the resulting in the methanol synthesis 8 methanol 12 is used directly as the final product. It can be used for example as carburetor fuel in corresponding internal combustion engines.
- the inventive method advantageously allows the reprocessing of carbon dioxide 6 from the flue gas 4 of power plants 1 and their use for the synthesis of fuels 14, 15, 16, in particular gasoline fuel 14, for the operation of internal combustion engines such as gasoline engines in automobiles.
- the inventive method can thus be used in a particularly advantageous manner for the treatment of the resulting in large quantities of flue gases 4 of power plants 1 from fossil fuels 2.
- the methanol 12 can be reacted in Dirne methyl ether 18 as a diesel fuel.
