    Fuels supply system for vehicles with Koehlendioxidspeicherung
    Description:
    Technical area:
    The invention relates to fuel supply systems for mobile drive devices.
    Background Art: In modern economies, vehicles are usually designed to be self-powered by in-vehicle oxidation (in, for example, internal combustion engines, gas turbines, fuel cells) of hydrocarbon compounds (e.g., gasoline, diesel, natural gas, kerosene, heavy oil) generate the necessary energy, mostly relying on hydrocarbon compounds from fossil sources, which are made available to vehicles via a network of refueling facilities. The oxygen required for the oxidation is supplied to the oxidation devices of the vehicles in the form of ambient air, with the result that the exhaust gas mass flow of the vehicles consists largely of the nitrogen gas already predominantly contained in the ambient air, this exhaust gas mass flow with the carbon dioxide contained in it from the vehicles emits and thus contributes to an increase in the carbon dioxide content of the atmosphere and to an increase in the atmospheric greenhouse effect
    To reduce this climatic effect of hydrocarbon-powered vehicles, vehicles have been proposed (eg, US Pat. No. 5,680,764A, U5652334982) which oxidize carbon and hydrogen containing propellants in a nitrogen-free environment to obtain a product gas consisting predominantly of carbon dioxide and water and thereby, after the deposition of water, allow a carbon dioxide storage in the vehicles. Such a nitrogen-free and oxygen-enriched (more than 1% by volume oxygen) oxidation environment is generated for example by the deposition of nitrogen from the ambient air by means of membranes or by the use of oxygen carried in the vehicle (see Yantovski E. Energy and Exergyi Currents, NOVA Science Publication, New York, 1994). 1 14/05/2012 09:09

The technology of underground final storage of carbon dioxide is still in the trial stage and raises serious questions about the long-term leak-tightness of the deposits.
    In the application EP 2348254Al, the gas mixture discharged from the vehicles and containing carbon dioxide is supplied to one or more production plants which synthesize a vehicle fuel from hydrocarbons from carbonaceous starting materials, which in turn can be supplied to vehicles. Although this avoids carbon dioxide emissions in the production plants according to EP 2348254A1 and EP 2325288A1, carbon dioxide must nevertheless be taken from the carbon cycle existing between vehicles and fuel production plants and stored (EP 2348254A1, paragraph 31.58), since the production plants for process energy production also contain other carbonaceous substances Be fed starting materials.
    In order to reduce the storage of carbon dioxide in the earth's atmosphere by hydrocarbon-powered vehicles without having to carry out an in-vehicle carbon dioxide capture and storage, fuels produced from biomass are used to an increasing extent. These have a comparison with conventional fossil fuels improved carbon dioxide emission balance, since the resulting in their oxidation and emitted from the vehicles amount of carbon dioxide in an equivalent amount is withdrawn by the regrowth of biomass back to the atmosphere. In fact, however, biofuels offered today will only accept carbon dioxide emissions (measured in carbon dioxide equivalents) reduced by no more than about 70¾ compared to fossil fuels. Although the use of lignocellulosic raw materials will increase this value in the future, the limitations of the feasibility of this technological approach still exist in the limited global agricultural and forestry production capacity.
    Alternative energy supply concepts for vehicles based on electrical energy, not on hydrocarbon compounds, but on the basis of electricity from renewable or nuclear sources, produce little or no carbon dioxide emissions. The current state of battery technology, however, does not only lead to traffic-capable vehicles in the 2 14/05/2012 09:09

This results from the low energy density of the currently used batteries compared to hydrocarbons.
    Object of the invention:
    The object of the invention is to provide a fuel supply system for energetic supply of mobile machinery and in particular of vehicles (water, land and air vehicles) available that allows a similar compared to today's vehicles drive power and range, while carbon dioxide emissions in both Earth atmosphere as well as in the form of deposits in the ground or in water avoids as possible. This avoidance of carbon dioxide emissions relates to the operation of the mobile machines themselves, but also their fuel supply system (in particular the production of fuels).
    Presentation of the invention:
    In the following discussion, the term " fuel " denotes a single combustible hydrocarbon compound or a mixture of several different combustible hydrocarbon compounds, which can be produced by a single or multi-stage synthesis process of carbon dioxide and hydrogen, possibly also with additional supply of oxygen. In particular, a fuel may be methane or methanol.
    In the present invention, a mobile machinery fuel supply system (6) (hereinafter referred to simply as "vehicles") is proposed based on a nearly closed coolant circuit. Here, in the vehicles (6) resulting from the oxidation of fuel and stored in-vehicle carbon dioxide can be used entirely for the synthesis of new fuel and this again the vehicles (6) are fed so that no carbon dioxide is produced, which emits into the atmosphere, processed industrially or should be stored. Instead, it realizes a near-closed carbon recycling system in which carbon is released into the environment only by the water emitted from the vehicles (6) or the fuel synthesis equipment (3) and the carbon dioxide dissolved therein in small amounts.
    The vorgestelite system is used to supply vehicles (6), which use as fuels to obtain their driving power in addition to combustible hydrocarbon compounds in the vehicles entrained oxygen (8). In addition, such vehicles (6) have 3 14/05/2012 09:10

By cooling and / or compression of water (11) is deposited, so that concentrated carbon dioxide (9) is available for in-vehicle storage. In some cases, the product gas produced before or after the separation of water is returned to the oxidation reaction in order to regulate their intensity and the physical properties of the exhaust gas stream. The oxidation device (12) in the vehicle may, for example, consist of one or more internal combustion engines (internal combustion engine, gas turbine), one or more fuel cells or combinations of the abovementioned possibilities.
    The presented fuel supply system for vehicles includes one or more refueling devices (2) which can supply the described vehicles (6) with oxygen (8) and fuel (7) (each of a high degree of purity) and can discharge carbon dioxide (9) from the vehicles. The oxygen and fuel supply takes place separately either in gaseous or liquid form. In addition, the supply system presented herein consists of one or more devices for splitting water into hydrogen and oxygen (4) and one or more fuel synthesis devices (3). A supply system according to the invention can also have intermediate storage and / or liquefaction devices for the substances mentioned.
    The concentrated carbon dioxide (9) taken from the vehicles is supplied from the individual refueling devices (2) entirely to one or more fuel synthesis devices (3). This can be done in liquid, gaseous or supercritical form. Also, these hydrogen fuel synthesis apparatuses (3) are supplied with pure hydrogen gas (10) from the water splitting means (4). From the carbon dioxide (9) and hydrogen (10) supplied to them, the synthesis devices (3) generate fuel (7) in a catalytic process adapted to the respective fuel. Systems for a catalytic conversion of carbon dioxide and hydrogen to methane or methanol are generally known: In the case of methane, for example, nickel-doped solid catalysts, in the case of methanol, for example, copper-doped solid catalysts are used. Such systems can be designed by a specialist and integrated into the overall process,
    In a fuel supply system according to the invention falls in the devices for the synthesis of fuel from hydrogen and carbon dioxide (3) only water (11) as the only by-product. The synthesis process for methane can be illustrated by the following reaction equation: 4 14/05/2012 09:10

    C02 + 4H2 > CH4 + 2H20 For the synthesis of methanol, the reaction equation C02 + 3H2 - > H3COH + H20
    The resulting water can be emitted from the fuel synthesis apparatus (3). In another advantageous embodiment of the supply network, this water is supplied in a recirculation mass flow (11a) partly or wholly to one or more plants for the splitting of water (4).
    The fuel produced in the fuel synthesis apparatuses (3) is supplied in its entirety to the refueling devices (2) in gaseous or liquid form and after any temporary storage.
    The pure oxygen (S) obtained in the apparatus for splitting water (4) in the production of the hydrogen (10) required for fuel synthesis corresponds, in accordance with the stoichiometric laws, to exactly that amount of oxygen which is required for complete oxidation of the fuel synthesizer (3) generated fuel is needed. For methane, this stoichiometric ratio can be given approximately in the following equations:
    Decomposition process of water: 4H20 - > 4H2 + 202
    Methane Synthesis Test: C02 + 4H2 - > CH4 + 2H20
    Oxidation of generated methane: CH4 + 202 - > C02 + 2H20 For methanol, the following equations express this stoichiometric ratio:
    Decomposition process of water: 6H20 - > 6H2 + 302
    Methanol synthesis process: 2C02 + 6H2 - > 2CH30H + 2Η2θ
    Oxidation of the produced methanol: 2CH30H + 302 - > 2C02 + 4H20
    Therefore, a fuel supply system according to the present invention can provide all of the oxygen (8) required by the fuel oxidation vehicles to the vehicles (6) without additional oxygen production equipment. For this purpose, in a fuel supply system according to the invention, the oxygen (8) produced in the devices for splitting water (4) is supplied partly or wholly to the refueling devices (2). This again can take place in gaseous or liquid form. 5 14/05/2012 09:11

    The devices for splitting water (4) can be used, for example, for an electrolysis process, but also for a thermal or thermochemical decomposition process. However, the energy required for this has to come from non-fossil energy sources (5) in order to ensure the principle underlying the presented fuel supply system of a C02 emission free energy supply of the vehicles.
    Since this is a stationary energy supply, this can be easily achieved by, for example, solar or wind energy systems. These as well as plants for the electrolytic splitting of water into hydrogen and oxygen are technically well studied and can be designed by the skilled person and integrated into the overall process.
    In one embodiment of the fuel supply system, oxygen (8) from the water splitting devices (4) is additionally supplied to the fuel synthesis devices (3) to operate the fuel supply system with a fuel whose synthesis process requires the supply of oxygen gas. Specifically, for example, dimethyl carbonate (CH30) 2C0 can be produced in the fuel synthesis apparatus (3) by a three-stage catalytic process:
    Methanol synthesis: C02 + 3H2 * > H3COH + H20 reverse water gas shift reaction: C02 + H2 - > CO + H20
    Dimethyl carbonate synthesis: 4H3COH + 2CO + 02 * > 2 (CH3Q) 2CO
    The principle of stoichiometrically adequate oxygen production for the oxidation of the fuel produced does not change anything in such an embodiment of the fuel supply system.
    The fuel synthesis devices (3) and the refueling devices (2) also meet their operating energy requirements from renewable energy sources (5). In a variant of the supply system according to the invention, the devices for synthesizing fuel (3) use the hydrogen (10) supplied to them in order to oxidize it with ambient air in, for example, an internal combustion engine or fuel cell for operating energy production. In another variant of the supply system according to the invention and shown diagrammatically in FIG. 2, the refueling installations (2) derive their operating energy from the oxidation of a portion of the fuel supplied to them by means of a portion of the oxygen supplied to them and lead the resulting carbon dioxide to the synthesis apparatus for fuel ( 3) after an analogous to the described in-vehicle water separation water separation (14a) was performed. 14/05/2012 09:11

    In order to ensure an adequate supply of fuel to an increasing number of vehicles and also to compensate for the low loss of carbon in the water emitted by the vehicles (6) and in the water emitted by the fuel synthesis devices (3), the supply system must have water and energy This can be done at a suitable place of the supply system, such as at the refueling devices (2), by feeding in gaseous, liquid, in the case of carbon dioxide also supercritical form.

    The invention is diagrammatically shown in FIGS. 1 and 2. In this case, the supply system (1) is reduced to only one refueling device (2), one device for the synthesis of fuel (3) and one device for splitting water (4) for reasons of simpler representation.
