Definitions
- the invention relates to a system for storing carbon derived from hydrogen. Furthermore, the invention relates to a method for storing coal-derived hydrogen.
- plasma gasification reactors are very maintenance-prone, since the electrodes must be changed regularly.
- the invention has for its object to store both regenerative and conventionally produced hydrogen in an efficient manner.
- the object is achieved by a system for storing coal-derived hydrogen, comprising a coal gasification reactor for gasification of coal, a steam power plant for power production, which is thermally coupled to the coal gasification reactor, a water gas shift reaction plant, which is connected to the coal gasification reactor to obtain the reaction gases of the coal gasification reactor, and a gas storage, wherein the gas storage is connected to the water gas shift reaction plant to store at least one of the product gases of the water gas shift reaction plant.
- a method for storing coal-derived hydrogen comprising a system according to one of the preceding claims, comprising the following steps:
- the system and method according to the invention have the advantage over conventional steam power plants that the storage of hydrogen instead of the complete power generation in a future Hydrogen economy cost possible as a by-product of a steam power plant is possible.
- the main component of the system is a coal gasification reactor, a thermally coupled steam power plant, a water gas shift reaction plant and a gas storage, which interact accordingly.
- reaction gases In the coal gasification reactor, carbon monoxide and hydrogen, which are typically produced by rapid oxidation in the coal gasification reactor, are produced as reaction gases.
- the reaction gases of the gasification have a temperature of for example 1500 to 1800 ° C, which is much too high for a subsequent hydrogen shift reaction.
- reaction gases heat the feed water of the boiler of the steam power plant for the production of electric current, for example, steam is produced at a temperature of about 530 ° C, whereby the reaction gases are cooled, in particular to below 700 ° C, preferably to 200 ° C to 500 ° C.
- the water gas shift reaction proceeds in particular with the addition of water in vapor form, ie by adding steam.
- the thermally coupled steam power plant ensures that the reaction gases of the coal gasification reactor are sufficiently cooled so that the water gas shift reaction can proceed at all. However, there is no active cooling is made, is consumed in the energy for cooling, but the heat of the reaction gases is used to operate the steam power plant, at least partially, so to generate steam for the steam power plant.
- coal gasification reactor is operated at very high temperatures, so that it provides almost exclusively hydrogen and carbon monoxide as reaction gases, for example 33% hydrogen and 60% carbon monoxide.
- a coal gasification reactor is usually operated at lower temperatures, for example at temperatures of maximum 1000 ° C to 1200 ° C, in order to then cool the reaction gases less active active, so that the overall efficiency is as high as possible.
- the resulting carbon monoxide as part of the cooled reaction gases of the coal gasification reactor is converted into hydrogen via the water gas shift reaction system.
- more hydrogen is available, which can be used.
- the additional hydrogen represents a part of the product gases of the water gas shift reaction system.
- the water gas shift reaction system may also include a high temperature and low temperature equipment part, whereby the carbon monoxide content in the production gases of the water gas shift reaction plant can be reduced.
- the product gases of the water gas shift reaction system ie mainly hydrogen, stored in a gas storage.
- the hydrogen can be used for hydrogen cars or other hydrogen applications.
- the hydrogen formed in the coal gasification reactor can be separated, for example via a downstream filter, so that only the cooled carbon monoxide is fed to the water gas shift reaction system as (cooled) reaction gas.
- the hydrogen produced in the coal gasification reactor ie the hydrogen as reaction gas
- the hydrogen from the water gas shift reaction plant ie the hydrogen as product gas
- the proportion of recovered hydrogen is thus maximum.
- the hydrogen produced in the coal gasification reactor is also fed to the water gas shift reaction plant and, via this, to the gas reservoir.
- the system always produces an excess of electricity that can be fed into the grid, partly because of the connected steam power plant.
- systems with plasma gasification reactors require at least a majority of the power to operate on their own. However, any surplus is needed at the latest for hydrogen production, ie it is directly consumed again.
- One aspect provides a separation system for separating hydrogen, which is arranged between the water gas shift reaction system and the gas storage, so that the gas storage stores only hydrogen.
- the hydrogen is separated from the remaining product gases of the water gas shift reaction system by means of a further subsystem, namely the separation system, and then stored in the gas storage, so that pure hydrogen is available.
- the separation plant may be a filter.
- the other product gases can also be separated or filtered so that they can also be stored separately.
- a carbonization plant for continuous or discontinuous hydrothermal carbonization of biomass wherein the carbonation plant is fed as starting material any biomass, which is subjected to a continuous or batch process in a continuous process of hydrothermal carbonation, in particular wherein the the carbonization liberated heat of reaction is used to dry the resulting coal-water slurry.
- a regenerative operation is possible in which any biomass in an upstream part of the plant is subjected to a hydrothermal carbonation in a continuous flow process or a batch batch process.
- the resulting coal can be dried with the heat of reaction from the hydrothermal carbonization prior to gasification.
- the carbonization unit may comprise a carbonization part, a drying part adjoining the carbonization part, and a heat exchanger, the heat exchanger leading the heat of reaction liberated during the carbonization in the carbonization part to the drying part.
- This is a energy-efficient carbonisation plant, since the heat of reaction released during the carbonization of the biomass is used to dry the coal produced during the carbonation, so that dried coal can be fed to the coal gasification reactor.
- any biomass, even very humid, such as organic waste can be used in the carbonization plant without pretreatment in order to produce the coal-water slurry by hydrothermal carbonation, which is also referred to as lignite-water slurry or HTC coal.
- the power consumption here is minimal.
- the steam power plant can serve as a heat sink, so that the water gas shift reaction system receives the reaction gases of the coal gasification reactor cooled.
- the reaction gases are therefore cooled due to the heat dissipated to the temperature required for the water gas shift reaction. Since the cooling of the reaction gases or the dissipation of the heat generated is used to heat the existing water in the boiler of the steam power plant and to generate steam, there is a correspondingly energy-efficient system.
- the coal gasification reactor may be a Koppers-Totzek reactor. Such a coal gasification reactor works with fine coal, which can work with different types of coal.
- the coal can be shredded in advance to the required grain size.
- the coal in an upstream part of the plant must be crushed to a certain granularity.
- the HTC coal ie the carbon-water slurry obtained from the carbonization plant, does not have to be comminuted before the subsequent gasification, since it is 8 to 20 nm in size, since a Kopper-Totzek reactor, for example, a grain size of less than 0.1 mm needed.
- the reaction gases of the gasification may mainly comprise carbon monoxide, in particular wherein the reaction gases include, inter alia, hydrogen.
- the product gases produced in the water gas shift reaction are processed by means of an upstream separation unit for the separation of hydrogen, so that only hydrogen is supplied to the gas storage.
- the coal is provided from fossil coal and / or from any biomass.
- the coal can therefore be made entirely from fossil coal, entirely from any biomass or even from a mixture. If a proportion of biomass is provided, it must first be carbonized accordingly.
- the comminuted coal, the lignite-water slurry produced from biomass, and / or the dried lignite-water slurry may generally be gasified in the coal gasification reactor with water and (air) oxygen.
- the system comprises a steam power plant, the system is a stationary, immobile or stationary system.
- the biomass waste is first dried as a biomass with a high energy input and then broken down into atomic elements. These can form toxic compounds on cooling, which could then escape during the combustion of the product gas. In order to avoid such compounds, the hot gases are actively cooled very quickly in order to prevent the external conditions necessary for the formation of compounds such as furans and dioxins.
- FIG. 1 shows a system 10 that can generate hydrogen from a biomass.
- the system 10 comprises a biomass feed 12, via which the carbonization plant 14 can be fed with the biomass to be carbonized.
- the carbonator 14, which is part of the system 10, serves for continuous or discontinuous hydrothermal carbonization of the biomass to produce coal.
- the carbonization unit 14 comprises a carbonization part 16, a drying part 18 adjoining the carbonization part 16, and a heat exchanger 20 which couples the carbonization part 16 to the drying part 18.
- system 10 includes a coal gasification reactor 22 coupled to the carbonator 14 to obtain the output of the carbonator 14.
- the coal gasification reactor 22 gasifies the coal, thus among other things the starting products of the carbonization plant 14, wherein the coal is gasified with the addition of water and (air) oxygen inter alia to carbon monoxide and hydrogen. This creates thermal energy that can be used.
- the thermal energy is utilized by a steam power plant 24 that is thermally coupled to the coal gasification reactor 22 so that feed water of a boiler of the steam power plant 24 is heated by the heat generated during gasification.
- the system 10 includes a water gas shift reaction unit 26 coupled to the coal gasification reactor 22 for the reaction gases the coal gasification reactor 22, which are cooled due to the thermal coupling with the steam power plant 24.
- the carbon monoxide obtained as the reaction gas from the coal gasification reactor 22 is converted to further hydrogen by adding water.
- the gas-shift reaction system 26 is adjoined by a gas reservoir 28, in which at least one of the product gases of the water-gas shift reaction system 26 can be stored.
- the one production gas may be hydrogen, which is why a separation plant 30 is provided for separating hydrogen, which is arranged between the water gas shift reaction plant 26 and the gas reservoir 28, so that the gas reservoir 28 stores only hydrogen.
- the carbonization system 14 is fed via the biomass feed 12 biomass, which is then carbonized in the Karbonmaschinesteil 16, that is converted to coal.
- the biomass can be heated initially, to then be converted by means of an exothermic reaction in a coal-water slurry, in particular a lignite-water slurry.
- the released heat is passed through the integrated heat exchanger 20 of the carbonization system 14 to the subsequent drying part 18, which serves to dry the coal-water slurry.
- the heat exchanger 20 serves as a heat coupling, so that the drying part 18 uses the heat released during the exothermic reaction of the carbonization to dry the coal-water slurry.
- the dried coal-water slurry is then fed to the coal gasification reactor 22, where the coal is gasified together with water and (air) oxygen with release of energy inter alia to carbon monoxide and hydrogen.
- the Karbonmaschinesstrom 14 is only optional, if hydrogen is to be obtained from biomass.
- coal gasification reactor 22 fed directly, which is then gasified with release of energy among other things to carbon monoxide and hydrogen.
- a mixture of biomass and fossil coal may be supplied to the coal gasification reactor 22.
- the coal gasification reactor 22 is operated at temperatures as high as almost exclusively carbon monoxide and hydrogen. This is done by rapid oxidation at high temperatures, mainly resulting in carbon monoxide and hydrogen as reaction gases.
- the coal gasification reactor 22 may be a Koppers-Totzek reactor which requires crushed coal for gasification, so that a comminution plant may be connected upstream, which comminutes the coal, in particular the fossil coal.
- the carbon-water slurry produced in the carbonation plant 14 does not have to be further comminuted, since the coal has already been sufficiently comminuted.
- the coal in the coal gasification reactor 22, the coal can be gasified at temperatures of 1600 to 1800 ° C in a flame of the coal gasification reactor 22, producing hydrogen and carbon monoxide (generator gas).
- the carbon monoxide (generator gas) is generated in accordance with incomplete combustion of coal with air, which is just not possible for example in a plasma combustion, especially since a working gas must still be used.
- the heat energy of the reaction gases is fed to and / or removed from the steam power plant 24, which is thermally coupled to the coal gasification reactor 22, in particular the boiler of the steam power plant 24.
- the feed water therein is due to the heat of the reaction gases heated so that the feed water evaporates.
- the steam may then drive one or more turbines of the steam power plant 24 for power production.
- the heating of the feed water with the reaction gases of the coal gasification reactor 22 cools the reaction gases accordingly, in particular the carbon monoxide as a reaction gas.
- the reaction gases are cooled to temperatures below 700 ° C.
- reaction gases in particular the carbon monoxide
- the reaction gases can be processed directly in the water gas shift reaction system 26, ie without intermediate active cooling, as is usual.
- the steam power plant 24, which is thermally coupled to the coal gasification reactor 22, serves as a heat sink, so that the water gas shift reaction plant 26 receives the reaction gases of the coal gasification reactor 22 cooled.
- the additional hydrogen is then separated via the separation unit 30 for separation, so that the gas reservoir 28 receives only hydrogen.
- the hydrogen which has formed as the reaction gas in the coal gasification reactor 22 may also have previously been separated off, in particular before the reaction gases are passed on to the water gas shift reaction plant 26, the branched off hydrogen being combined with the additional hydrogen.
- the branched hydrogen are stored in the gas storage 28 together with the additional hydrogen.
- the gas storage 28 may be preceded by a compression system to compress the gas to be stored.
- the system 10 of the coal which is provided in particular from biomass, can produce almost exclusively hydrogen and carbon monoxide, namely more than 90%.
- the resulting ash accumulates liquid in the reactor bottom and is granulated in a water bath.
- Simplified shown in the coal gasification reactor 22 following reaction C6H2O + 5 H2O 6 CO + 6 h .
- the entire process is very energy efficient, so that additional electricity can be produced, whereas in systems with plasma gasification no surplus energy is obtained, if the hydrogen is to be stored.
