The invention relates to a hydrogen supply system, which is used to fuel vehicles that run on fuel cells. According to the invention the hydrogen supply system includes a hydrogen supplying point and the mobile hydrogen production system, and produced by the mobile hydrogen is fed into the system hydrogen supply point. The technical result of the invention is to provide a hydrogen supply system with the maximum use of existing infrastructure.

DESCRIPTION OF THE INVENTION

The present invention relates to a hydrogen supply system, and the mobile hydrogen production system used for vehicles that run on fuel cells, and for distributed hardware operating fuel cell.

Currently, vehicles are being developed which use as the energy source of fuel cells, and the decentralized equipment of the fuel cell. For example, automobile, actuated by the fuel cell, hydrogen from the coupler receiving tank, implementing the principle of which consists in that the fuel cell is supplied with hydrogen to produce electrical energy, and electrical energy obtained driven motor. This principle of the energy applied to all vehicles, including not only automobiles, moving on four wheels, but also motorcycles, running on the rails of the train, etc. Using the device, the drive mechanism which is operated by the energy of the fuel cell can achieve high energy efficiency, reduce CO2 emissions and almost eliminate emissions of NO X. For environmental emissions of CO 2 and NO X are a global problem.

In accordance with one of the proposed system for a vehicle driven by the fuel cell in a car enters a starting material, is not subjected to pre-reformed, and the substance of the vehicle to produce hydrogen by reforming, which can be used in a fuel cell. However, it seems that the practical implementation of such a supply system will be possible after many years, because such a system causes a number of problems to be solved, such as the duration of time required to run, adaptability to multiple start and stop as well, and the freezing of materials in cold areas . Therefore, it appears that currently find widespread use vehicle driven by a fuel cell using hydrogen in the tank in the implement under high pressure. The big problem with the widespread use of vehicles that run on fuel cells operating by supplying hydrogen under high pressure from the tank attachment, is the development of infrastructure for hydrogen supply (tank car coupler). In other words, in this case, a problem arises infrastructure embracing a large coverage area and allowing the absence of said constraints provide hydrogen vehicles using fuel cells. Currently, as a rule, developing an infrastructure for hydrogen supply, which can be used to implement any of the following three ways:

(1) Hydrogen is produced in large quantities at a factory etc. and transported to the hydrogen supply points (or columns of hydrogen refueling stations) in the form of liquefied hydrogen or hydrogen under high pressure, using a tanker or the like;

(2) Hydrogen is produced in large quantities at a factory etc. and transported to the items supply conduit for hydrogen;

(3) hydrogen produced by steam reforming city gas or liquid material (desulfurized naphtha, gasoline, kerosene, light oil fractions, methanol and the like) using the reformer unit installed in the hydrogen supply section.

The method (1) has disadvantages in terms of transportation efficiency of tankers, restrictions on transportation distance loss due to evaporation during transportation of material, transportation costs and the like. Method (2) requires a large-scale software, such as stacking the new pipeline and the compressor for the feed gas, so that the cases in which this method can be applied are limited. The advantage of the method (3) is that it enables a high degree of use of existing infrastructure, which is a domestic pipework for gas and petrol stations station. However, this method has disadvantages in that the system of the reformer unit is costly, and it is required to accommodate a large area (because the system is large), and in that the system during its operation and maintenance because of their complexity, it requires the use of high technology, difficult to ensure that the safety of personnel during maintenance and operation of the system.

From the foregoing it follows that the development of infrastructure for hydrogen supply as a basic condition for widespread use of vehicles that run on fuel cells, due to the solution of many problems, so it seems to be a considerable time is required for a wide use of such vehicles.

In connection with the situation described above, the present invention provides a hydrogen supply system that provides the ability to supply hydrogen cars powered by fuel cells and distributed hardware that use fuel cells, with the maximum use of existing infrastructure and the use of the advantages of the well-known method in which hydrogen is through a steam reforming city gas or liquid material (desulfurized naphtha, gasoline, kerosene, light oil fractions, methanol and the like) via the reformer system placed in the hydrogen supplying point and, besides solving the problem of high cost of the reformer system, the need to accommodate a large area of ​​the device, difficulty security personnel for maintenance and operation of the system, and similar problems, which are disadvantages of the method.

Selection of a particular fuel depends on economic, regional and social conditions. For example, when the mobile hydrogen production system moves within a large number of regions, in some cases it has to produce hydrogen from a variety of starting materials, depending on the capabilities of each region. Therefore, it is preferable that the mobile hydrogen production system can produce hydrogen by supplying it with various substances, including two or more kinds of the starting materials.

Preferably, before the membrane reformer desulfurizer was set to remove odorant contained in city gas, or pre-reforming installation that provides a single hydrocarbon conversion in the fuel contained in the hydrocarbon gas consisting mainly of methane. Furthermore, in the case of using methanol, etc. preferably mounted vaporizer for vaporization thereof.

Preferably, the mobile hydrogen production system is provided with a reservoir of starting material. When used to produce hydrogen using a mobile system diagram, according to which hydrogen is obtained by feeding in a starting material at the location of the item hydrogen supply and the hydrogen produced in the direct supply point. However, due to the presence of mobile hydrogen tank system to the starting material may be prepared in advance, when the system is moving, when the distance to the hydrogen supply item is large, and therefore the time of producing hydrogen can be substantially reduced. The hydrogen produced during movement, is stored in the storage means are available. As the storage means can be selected hydrogen tank and a hydrogen storage device provided with alloy absorbing hydrogen. In addition, for charging the reservoir has a hydrogen compressor for compressing hydrogen.

In this case, the mobile hydrogen production system is provided with a driving mechanism using a fuel cell and produces hydrogen by supplying its source material from the reservoir, even during its movement.

For the mobile hydrogen production system according to the present invention in one of its embodiments hydrogen supply points are placed in two or more places, and the mobile system, all these circles hydrogen supply points or moves towards it.

Mobile hydrogen production system is preferably provided with a means of capturing CO 2, since CO 2 is preferably captured and reused to reduce its emissions, protecting the environment from the release of CO 2. In this case, it is preferable that was captured by the CO 2 by absorption using absorbent available in the mobile hydrogen production system, and then carried to the regeneration of the absorbent used in the regeneration of the absorbent station.

The recovered CO 2 is reused in industry or associated with the formation of non-volatile compounds, which is one of the measures to counter global warming, and, moreover, are sometimes used in activities related to emission standards.

2 shows one embodiment of a vehicle placed on it with the production of hydrogen, which can be used in the hydrogen supply circuit shown in Figure 1. The vehicle is placed on a system, it is an embodiment of a mobile system for producing hydrogen. 2 illustrates the position of the supply system, in which the vehicle with a system for producing hydrogen produces hydrogen supply at the point of hydrogen supply.

The illustrated vehicle 1, which taken hydrogen production system 2 is provided with hydrogen production, placed on the rear of the loading platform. Hydrogen production system 2 includes a container 8 located in the membrane reformer 3, the evaporator 20, a compressor 4, a hydrogen, the hydrogen tank 5, a tank 6 with the solvent and CO 2 tank 7 with the starting material.

By using the membrane reformer hydrogen production system 2 can be made compact and thus easily loaded onto the vehicle.

The present inventors have previously proposed various types of membrane reformer that provides a compact hydrogen production system able to be easily loaded on the vehicle, etc. (See., E.g., provisional publication of Japanese Patent Application №9-2805 (№2805 / 1997)).

Furthermore, in step 9 the hydrogen supply vehicle 1 on which the hydrogen production can receive natural gas 10, electrical energy and water 11.

1 with the vehicle placed thereon hydrogen production system configured as described above, produces hydrogen from the membrane reformer 3 while household gas supply system 10 and power / water 11. The evaporator 20 is designed to supply steam used in the process of steam reforming domestic gas 10 (including a pre-reformer). The hydrogen is compressed by the compressor 4 and store them in the hydrogen tank 5, or to the hydrogen tank 12 installed in the hydrogen supplying section 9. The carbon dioxide formed during the production of hydrogen is absorbed by an absorbent such as an amine (solvent: CO 2) located in the reservoir 6 CO 2 solvent.

Item 9 supplies the hydrogen supply hydrogen to the vehicle 14 using the fuel cell as a power source, using a gas of high pressure column 13.

In the embodiment shown in Figure 2 to vehicle 1 is placed on it producing hydrogen gas supplied household. However, natural gas contains an odorant. Therefore, the odorant is removed at a stage preceding reformed in the reformer 3 by a desulfurizer (not shown).

Also, the vehicle system 1 placed thereon is arranged to adapt the incoming feed material. For example, it is provided with pre-setting one-step reforming process for a hydrocarbon conversion process, contained in the starting material, a hydrocarbon gas consisting mainly of methane.

On the vehicle 1 is set to a starting material reservoir 7, and therefore, when the distance to the point 9 hydrogen supply is large, the hydrogen can be prepared in advance during the movement of the vehicle 1, whereby the production process can be significantly reduced. Furthermore, by providing the vehicle 1, which is allocated producing hydrogen actuator using as a source of energy fuel cell, the hydrogen produced can be a source of energy for the movement of the vehicle 1. In this case the vehicle 1 is furthermore provided with placing a reservoir for supply of water required for the steam reforming reactions. The hydrogen produced during the motion, accumulate in the hydrogen tank 5, which is a means of storing hydrogen. To create a hydrogen storage instead of the hydrogen tank 5 can be used a means of containing alloy absorbing hydrogen.

Given that the hydrogen stored in the hydrogen tank 5 in this manner, the vehicle 1, which is allocated the production of hydrogen, the suspension is provided, which allows the system to restrict vibration 2 to generate hydrogen as much as possible.

Item 9 is provided with a supply of hydrogen sensor hydrogen leakage or the like (Figure 2 is not shown), so that in the event of a hydrogen leak could take the necessary measures to ensure safety.

3 shows one embodiment of a reforming system 3 membrane. In such a reformer 3-mixed gaseous fuel and steam is introduced through the feed pipe 30 material. The introduced mixed gas is reformed in the presence of a reforming catalyst layer 31 of the process, thereby forming a gas containing hydrogen. Contained in the produced hydrogen gas passes through the membrane 33, permeable hydrogen (as a membrane element), and flows out of outlet 32. In addition, the gas (CO 2, CO, H 2 O, unreacted material) which passes through the permeable hydrogen membrane 33 is discharged through the residual gas outlet tube in the installation and use as fuel. A reforming catalyst layer 31 and the membrane process 33 placed in the inner cylinder 34.

Membrane reformer system 3 is provided with a burner 36 mounted in the central opening 35. The heat shield tiles burner 36 burns combustible gas introduced through the pipe 37 for supplying the fuel gas together with air via the air supply pipe 38. The resulting combustion gas mixture to the reforming catalyst layer 31 supplied thermal energy required for the steam reforming reaction and sufficient to maintain the reforming catalyst layer 31 at a predetermined temperature. The inner cylinder 34 outside the closed casing 39, and the exhaust gas (combustion) is discharged through a pipe 40 of the exhaust gas outlet.

In this embodiment, in the reformer catalyst can be any catalyst used in the reforming process, which is usually used in the preparation of the aforementioned starting substances by means of hydrogen steam reforming. To allow different kinds of starting materials are acceptable, for example, a catalyst based on nickel or ruthenium applied in the case of a hydrocarbon substance such as city gas, LPG and gasoline, and a catalyst based on copper / zinc or platinum is suitable for oxygenate such as methane and methanol (DME). The hydrogen permeable membrane 33 is made of metal and hydrogen can be obtained only pass therethrough. Since the metal membrane selectively allows only hydrogen, the separated hydrogen has a purity of up to 99.999%, and hence such hydrogen is very suitable for use in a fuel cell.

Furthermore, it should be noted that the resulting hydrogen is selectively separated from the reaction product using a hydrogen-permeable membrane 33 and the partial pressure of hydrogen in the reaction product decreases. Therefore, the reaction proceeds in the direction of increasing the amount of hydrogen, and thus the degree of completeness of reaction at the same temperature increase. In other words, although during the methane steam reforming temperature in the reaction zone should be about 800 ° C, the same value of the degree of reaction completeness (corresponding to a temperature of 800 ° C) can be realized at a temperature from 500 to 600 ° C, which is achieved according to the invention 33 by using a membrane through which a membrane reformer 3 extends hydrogen. Thus, since by passing through hydrogen permeable membrane 33 has the chemical equilibrium can be shifted in the direction of increasing the amount of hydrogen generated, the reforming reaction temperature is reduced to a value of 200 to 300 ° C. Thereby achieving savings heat required for heating the reaction gas, and significantly increases the thermal efficiency of the process. Furthermore, since the reaction temperature is low, the system proposed for inexpensive material having low heat resistance can be used, and therefore the system cost can be reduced. The hydrogen permeable metal membrane is from 5 to 50 microns thick and mounted on a porous inorganic material layer so as to provide selective passage of hydrogen through it. A porous inorganic material under the metal membrane permeable to hydrogen provides a basis for fixing and holding the metal for the hydrogen permeable membrane and made of porous non-woven fiber made of stainless steel, porous ceramic, glass or the like material. The thickness of the porous substrate is from 0.1 mm to 1 mm. Also, as an element, which imparts structural strength, preferably a wire mesh consisting of a single layer or a plurality of layers. It is better that metal hydrogen permeable membrane was a non-porous layer made from an alloy containing palladium (Pd), or an alloy containing nickel (Ni), or an alloy containing vanadium (V). As alloy including Pb, may be selected alloys of Pd-Ag, Pd-Y, Pd-Ag-Au, etc. As an alloy including V, alloys can be selected V-Ni, V-Ni-Co, etc. As an alloy containing Ni, may be used and the like LaNi 5 A method of manufacturing a non-porous layer of palladium is described for example in U.S. Patent №3155467.

As described above, the membrane reformer unit 3, shown in Figure 3, can provide a high purity hydrogen with high efficiency and the best type of reformer is used in the hydrogen supply system in accordance with the present invention. In addition, the high efficiency of the membrane reformer 3 lets you compact it, and therefore it can easily be loaded onto a vehicle, on which is placed the production of hydrogen.

Driving mobile system for producing hydrogen of the present invention has been described above for the case of the vehicle 1 adapted to produce hydrogen, as shown in Figure 2. However, depending on the intended type of fuel, especially in the case of many types of fuel, various embodiments of a system may be implemented. Possible schemes embodiments of mobile systems for hydrogen which can be used in the present invention will be disclosed below with reference to Figures 4 and 5.

4 is a diagram corresponding to the case of using a hydrocarbon fuel such as natural gas, gasoline and liquefied petroleum gas, and oxygen-containing hydrocarbon such as dimethyl ether and ethanol.

This scheme includes as major elements a booster compressor 41, desulfurizer 42, the installation of pre-reformer 43, an evaporator 44, a reformer 45, the heat exchanger 46, compressor 47, and means 48 for storing hydrogen. In the case of liquid precursor 41 between the booster compressor and an evaporator arranged desulfurizer 42.

Below it will be described a case of using this scheme as a domestic fuel gas. First, natural gas is compressed to about 10 atmospheres booster compressor 41. The city gas odorant comprising a compound comprising sulfur is removed using desulfurizer 42. Thereafter, natural gas 43 is directed to a pre-reformer. At the same time a natural gas fed water required for the reforming reaction in the vapor phase. Water is fed to the preliminary reformer 43 in the form of steam coming from the evaporator 44. The apparatus 43 pre-reforming natural gas and steam are reacted with each other at a temperature of from 300 to 500 ° C, and contained a small amount of city gas hydrocarbon higher compared to ethane, methane or converted to CO, CO 2, H 2. After pre-reforming the resulting gas is sent to the reformer 45, where methane, a component of city gas, by steam reforming reaction process conducted at a temperature of 500 to 600 ° C, was prepared CO, CO 2 and H 2. Of these substances is separated from the rest of the gas only via H 2 separation membrane installed in the catalyst bed, which has a reformer 45, and after cooling in the waste heat heat 46 H 2 is fed to the compressor 47. In this case, the reformer 45 may be used membrane reformer illustrated in Figure 3, or a reformer (or other performance) within the housing which is further installed membrane for hydrogen separation.

The resulting pre-reforming the gas, which in the reformer 45 is partially separated H 2 may be used as a heat source for the reformer 45. Hydrogen is compressed in the compressor 47 flows into the hydrogen storage means 48 (the hydrogen reservoir alloy, absorbing hydrogen, etc.).

When this scheme is used the system for liquid fuel such as gasoline, compressed incoming fuel booster compressor 41 and then fed to the evaporator after passing through a desulfurizer 42. In this case, almost all of the liquid component, such as gasoline, is converted to install a pre-reformer 43 with a low hydrocarbon molecular weight, such as methane.

The circuit shown in Figure 5, includes as major elements a booster compressor 51, an evaporator 54, heat exchanger 56, compressor 57, and means 58 for storing hydrogen. In this scheme, methanol and dimethyl ether can be used as a fuel source. This fuel does not contain compounds containing sulfur, and therefore there is no need to use a desulfurizer.

When methanol fuel is selected, the first pre-mixed with water, methanol and the resulting mixture is fed into the evaporator 54. As described above, as the reformer 55 uses a membrane reformer or a reformer, comprising a housing and a membrane for separating hydrogen .

The reformer 55 chemical reaction proceeds at a temperature of 200 to 300 ° C. The design and function of the heat exchanger 56, compressor 57, and means 58 for storing hydrogen in this case are the same as described above and with reference to Figure 4, heat exchanger 46, compressor 47, and means 58 for storing hydrogen.

hydrogen supply system in accordance with the present invention is not limited to the examples disclosed above embodiments, and within the scope and technical spirit of the invention may be changes, modifications and additions obvious to a person skilled in the art.

Shown in Figure 2 the vehicle 1 is adapted to produce hydrogen may be a trailer. In this case, you need only for a certain period of time to establish a system to produce hydrogen in the hydrogen supply point. This system is acceptable for the hydrogen supply points equipped with technical means capable to store and store large amounts of hydrogen.

From the foregoing description that the present invention provides a hydrogen supply system allowing feeding hydrogen into the car driven by using the fuel cell and thus utilizing the existing infrastructure available.
