Definitions
- the invention relates to a method for producing a hydrogen-containing product gas from liquid or gaseous hydrocarbons.
- the hydrogen obtained is used, for example, for the purpose of operating a fuel cell system.
- the object of the present invention is to provide a method for producing a hydrogen-containing product gas from liquid or gaseous hydrocarbons, the reformer system having an improved cold start and load change behavior, so that hydrogen can be provided very quickly in the required amount.
- the method according to the invention is preferably carried out in a reformer system which has a combustion chamber, a mixing chamber and a reformer unit.
- the generation of a hydrogen-containing product gas from liquid or gaseous hydrocarbons comprises the following steps:
- a partial oxidation of a first hydrocarbon stream with a first oxygen-containing gas stream takes place in the combustion chamber of the reformer plant, a first product gas stream being formed which contains hydrogen.
- a second hydrocarbon stream is reformed with water, producing a second product gas stream which also contains hydrogen.
- the first and the second product gas stream are then mixed in the mixing chamber of the reformer system, whereby a third product gas stream is formed.
- Liquid or gaseous hydrocarbons are understood here to mean both relatively short-chain hydrocarbons and their derivatives (e.g. methane, methanol) and more complex hydrocarbon compounds (such as those found in gasoline).
- a strict separation of the combustion chamber and the mixing chamber is structurally not necessary in the reformer system. Rather, the combustion chamber can also represent an area in the interior of the reformer system in which the partial oxidation preferably takes place, while the mixing process of the two product gas streams predominates in another partial area of the reformer system.
- the basic processes during the partial oxidation and the reforming, in particular the steam reforming, are to be explained below.
- the partial oxidation produces carbon monoxide (CO) as a by-product, which must be removed from the product gas stream for the operation of fuel cells.
- the primary reaction equation for partial oxidation is: C m H n + m / 2 O 2 -> m CO + n / 2 H 2 .
- C m H n stands for a hydrocarbon compound, where m is the number of carbon atoms and n is the number of hydrogen atoms. It is known that the quantity of the educt gas streams is determined in accordance with the specified reaction. If the oxygen addition is too high, complete oxidation takes place. In this case, the products would be carbon dioxide (CO 2 ) and water (H 2 O), which would reduce the efficiency in terms of hydrogen production.
- two product gas streams are generated in the reformer system, the first product gas stream having a significantly higher temperature than the second product gas stream due to the partial oxidation.
- a third product gas stream is formed which is of sufficient volume to enable intensive heat transfer from the third product gas stream to the reformer unit.
- the reformer unit in which mainly the endothermic steam reforming takes place, is quickly warmed up after the cold start and during highly dynamic load changes, as a result of which the hydrogen yield is quickly adjusted to the level required for the subsequent energy generation.
- the first and the second product gas stream are mixed in countercurrent. This means that the first product gas stream of the partial oxidation flows into the mixing chamber in the opposite direction to the second product gas stream of the reformer unit. This means that the two product gas streams are almost completely mixed. is sufficient, whereby a third product gas stream is formed, which has a substantially uniform temperature distribution. This has the advantage that uniform heat input into the reformer unit is thus also ensured by the third product gas stream.
- the third product gas stream comes into direct contact with the reformer unit.
- the third product gas stream can, for example, be directed outside the reformer unit.
- the second hydrocarbon stream is mixed with a second oxygen-containing gas stream after the reforming.
- the second hydrocarbon stream is then oxidized, generating further hydrogen.
- an essentially three-stage reformer unit is formed, in which three chemical conversion processes take place in the flow direction of the second hydrocarbon stream.
- methanation takes place, in which, for example, complex hydrocarbon compounds (C m H n ) are converted exothermically into methane (CH 4 ).
- steam reforming takes place at increasing temperatures. This mainly results in the endothermic cleavage of the methane.
- a so-called shift reaction takes place subordinate, with the aid of excess water converting the carbon monoxide generated by the steam reforming into carbon dioxide.
- This is followed by the addition of oxygen and the oxidation of the carbon still hydrogen methane. Hydrogen is also consumed in this oxidation, but a methane-free second product gas stream is produced in this way. This is of great importance in particular with regard to the further use of the product gas stream for operating a fuel cell.
- the first and the second hydrocarbon stream are regulated as a function of the temperature in the reformer system. This means, for example, that a larger amount of the first hydrocarbon stream is fed to the reformer system in the cold start phase (ie at low temperatures). This has the consequence that the exothermic partial oxidation takes place increasingly. As a result, a sufficiently large thermal energy for heating the reformer unit can be made available very quickly.
- the carbon monoxide portion of the third product gas stream is reduced in a cleaning system.
- the cleaning system is connected downstream of the reformer system and ensures the required purity of the hydrogen-containing product gas for further use in a fuel cell system.
- the remaining portion of the carbon monoxide still contained in the product gas can be reduced to concentrations of less than 1,000 ppm, or even 10 ppm.
- the hydrogen-containing product gas produced is therefore also suitable for low-temperature fuel cells.
- a method for producing a hydrogen-containing product gas from liquid or gaseous hydrocarbons in which a reformed and purified product gas stream with a high hydrogen content is fed to a fuel cell system and converted there for energy generation, the exhaust gas removed from the fuel cell system being used to heat the reformer unit is used.
- the reformer unit can thus In addition, a heat flow can be made available that supports the heating process of the reformer unit.
- Fig. 1 is a block diagram of a reformer system according to the invention with a downstream cleaning system and a fuel cell system.
- the reformer system shows a reformer system 3 which is suitable for carrying out the method according to the invention for producing a hydrogen-containing product gas 1 from liquid or gaseous hydrocarbons 2.
- the reformer system has a combustion chamber 4, a mixing chamber 5 and a reformer unit 6.
- the reformer unit 6 is encapsulated with respect to the interior of the reformer system 3 and has only one outlet 26 through which the second product gas stream 12 can flow into the mixing chamber 5.
- a first hydrocarbon stream 7 and a first oxygen-containing gas stream 8 are introduced into the combustion chamber 4.
- the oxygen in the gas stream 8 serves as an oxidizing agent for the hydrocarbons 2 in the first hydrocarbon stream 7.
- the type of hydrocarbons 2 is not limited here, which means that complex hydrocarbons 2, such as to be found in petrol, for example, can be introduced into the reformer system 3.
- a single activation eg by sparking
- Temperatures of approximately 900 to 1000 ° C. occur in the combustion chamber 4.
- the pressure is approximately 1.427 bar. Air is used here as the oxygen-containing gas.
- first product gas stream 9 which has a hydrogen content of approximately 27%.
- the first product gas stream 9 has in particular approximately 25% carbon monoxide and 47% nitrogen.
- the hydrogen content of the resulting first product gas stream 9 can, however, be up to about 50%, the carbon monoxide content being about 3 to 4%.
- a reforming of a second hydrocarbon stream 11 with water 19 is carried out in the reformer unit 6, a second product gas stream 12 being formed which contains hydrogen 10.
- the reforming of the second hydrocarbon stream 11 takes place essentially by the so-called steam reforming. Due to its oxygen content, water 19 acts on the one hand as an oxidizing agent in order to separate the hydrogen contained in the second hydrocarbon stream 11 from the carbon and on the other hand itself contributes to hydrogen production. For pure steam reforming processes, therefore, the highest hydrogen yields of all reforming processes result even at a lower temperature level.
- different catalysts are used, all of which are activated by reduction with hydrogen or carbon monoxide and must be kept in the further course with the exclusion of oxygen. Steam reforming reactions are highly endothermic and therefore require external heat sources.
- the hydrogen The second product gas stream 12 is therefore above that of the first product gas stream 9, the carbon monoxide content being lower.
- the second hydrocarbon stream 11 is first passed through a first evaporator 25, in which liquid constituents of the gasoline are brought into a gaseous state.
- the evaporated gasoline is mixed with also evaporated water 19. This mixture is then introduced into the reformer unit 6.
- the reformer unit 6 is designed here with a primary reformer 22 and a secondary reformer 21.
- a methanization takes place first. This essentially involves a slightly exothermic conversion of complex hydrocarbons in the gasoline to methane. So that this methanation can already take place at temperatures of approx. 400 ° C., 23 catalysts are used in this sub-area, which for example contain components of nickel, rhodium, cobalt or platinum.
- the steam reforming primarily follows in the second partial area 24.
- an exothermic shift reaction with water takes place (to a small extent) for the conversion of the carbon monoxide.
- the steam reforming is preferably operated with an excess of water.
- a second oxygen-containing gas stream 14, in particular air, is supplied. This is followed by an additional oxidation in the secondary reformer 21 at a pressure of approximately 1.44 bar and a temperature of 740 ° C. Residual amounts of methane are removed from the second product gas stream 12.
- the second product gas stream 12 then has approximately a hydrogen fraction of approximately 47%, a carbon monoxide fraction of 9% and a water fraction of 35%.
- the division of the first hydrocarbon stream 7 into the second hydrocarbon stream 11 is preferably carried out in a ratio which is approximately 2: 3.
- the hydrocarbons 2 are, for example, gasoline, with approximately 10 kg of gasoline / h being required for a specific output of the fuel cell system 17, the first hydrocarbon stream 7 is accordingly approximately 4 kg / h and the second hydrocarbon stream 11 is approximately 6 kg /H.
- the first 9 and the second product gas stream 12 are mixed in the mixing chamber 5.
- the combustion chamber and the mixing chamber are not structurally separated from one another. In contrast to a spaced arrangement of the combustion chamber 4 from the mixing chamber 5, the embodiment shown prevents, for example, heat transfer from the hot first product gas stream 9 to additional walls of the combustion chamber 4 or the mixing chamber 5.
- the delimitation from a combustion chamber 4 and a mixing chamber 5 was carried out in particular for a more detailed explanation of which chemical or physical processes take place in these areas of the reformer plant.
- the first 9 and the second product gas stream 12 form a third product gas stream 13 in the mixing chamber 5, this being used to heat the reformer unit 6.
- the third product gas stream 13 thus formed has a uniform temperature distribution and flows past the reformer unit 6 on the outside.
- the third product gas stream 13 comes into contact with the reformer unit and thus ensures the amount of heat necessary for the endothermic steam reforming.
- This heat transfer process keeps the reformer's start and load change times as short as possible.
- the thermal efficiency of steam reforming can also be increased by the fact that further heat accumulating in the overall process, such as. B. the heat of the exhaust gas 18 of the fuel cell 17 is used for steam reforming.
- it is desirable to generate a product gas stream 12 already during the reforming which preferably has no residual portion of, for example, methane. Due to the temperatures (approx.
- the second hydrocarbon stream 11 begins to methanate. This means that a large number of the complex hydrocarbons 2 (C m H n ) are converted into methane (CH 4 ). This methanation process is followed by steam reforming in the direction of the outlet 20.
- the second hydrocarbon stream 11 is mixed with a second oxygen-containing gas stream 14 after the reforming. Oxidation of the second hydrocarbon stream 11 now follows in the direction of the outlet 20, further hydrogen 10 being generated and the possibly remaining amount of methane in the hydrocarbon stream 11 being converted.
- the third product gas stream 13 thus produced has a carbon monoxide content which is so high that use for fuel cells is very problematic. For this reason, the carbon monoxide content of the third product gas stream 13 is reduced in a subsequent cleaning system 15. A conversion of the carbon monoxide takes place in the cleaning system 15. In this way, the carbon monoxide concentrations in the purified product gas are reduced from 16 to less than 1000 ppm, in particular less than 100 ppm.
- the heating device 27 is flowed through, for example, by the hot exhaust gas 18 of a fuel cell system 17 and / or a hydrocarbon-containing heating gas 26. Such a heating device 27 shortens the start time which the reformer unit 6 requires until it reaches the temperatures required for steam reforming.
- the exhaust gas 18 or the heating gas 26 is then fed to the evaporators 25, where they ultimately Lich the mixture of the second hydrocarbon stream 11 and the water 19 are added. In this way, the hydrogens or hydrocarbons still contained in the exhaust gas 18 or heating gas 26 can be used for steam reforming in the primary reformer 22.
- a process sequence suitable for use in modern fuel cells for the production of hydrogen from gaseous or liquid hydrocarbons by means of steam reforming and partial oxidation can consequently be realized.
- Product gas flows for heating the reformer unit enable operation of the reformer system even with very dynamic load changes.
