Description

[0001] P240421-07 Reactor gas plant with engine and generator 1 Electric generator plant with combustion engine in combination with a reactor plant based on an alkaline electrolysis plant. Electric generator plant with combustion engine in combination with a reactor plant based on an alkaline electrolysis plant for the production of a fuel gas with a high oxygen content from a carrier gas and using the hydrogen and oxygen produced during electrolysis, and the process for producing a fuel gas with a high oxygen content using the reactor. In biogas plants, it is a known practice that the biogas produced is used as a fuel for combustion engines, and the combustion engines drive electric generators. Natural gas is used as an example of a carrier gas. Natural gas consists mainly of methane and contains traces of ethane, butane, propane, nitrogen, carbon dioxide, sulfur, and helium. The actual composition depends onThe composition varies from deposit to deposit. In this case, we assume a methane-rich natural gas of end-user quality. Producing a mixed gas can improve the CO2 balance, for example, when heating furnaces in steel, glass, or cement production, while also reducing the cost of producing the fuel gas compared to existing methods. German patent DE 2 220 617 A describes a process for producing hydrogen in which a mixture of methanol and water is passed in vapor form at temperatures of 150 to 350 degrees Celsius and normal or elevated pressure over a catalyst, and unreacted water vapor and carbon dioxide are removed. Various catalysts, such as copper, zinc, and / or manganese, are mentioned for this purpose. Furthermore, German patent DE 690 06 428 T2 describes a hydrogen evolution electrode that possesses high durability and stability.P240421-07 Reactor gas system with motor and generator enables energy cost reductions in hydrogen production. The electrode according to the invention has a coating of an oxide made of at least one metal selected from nickel and cobalt, to which titanium and zirconium components are additionally added. These electrodes were developed for the electrolysis of sodium chloride or water. German patent application DE 10 2015 003 003 B4 relates to an alkaline photoelectrochemical cell, a method for its production, and a method for the light-driven production of hydrogen and oxygen. The main claim reads: Photoelectrochemical cell for the light-driven production of hydrogen and oxygen from an aqueous medium in an alkaline environment, comprising a photoelectrode arranged on the light side, a counter electrode arranged on the shadow side, a separator arranged between the photoelectrode and the counter electrode, and a separator located on both sides of the separator.a reaction chamber extending from the surface, which can be filled with the aqueous medium and in which basic conditions prevail when the aqueous medium is filled, wherein the photoelectrode comprises a light-side oriented, transparent substrate which is coated in the direction of the separator with the following layer sequence: a) a transparent, electrically conductive layer; b) at least one partially transparent, layer-by-layer silicon-based solar cell; c) a coupling layer bordering the reaction chamber; characterized in that the coupling layer is multilayered, namely at least d) with a transparent adhesion-promoting layer applied directly to the aforementioned or a further solar cell, which consists of one of the following metals or an alloy of one or more of these metals: nickel, chromium, tungsten, hafnium; e) with a mirror layer applied directly to the adhesion-promoting layer, which consists of one of the followingmetals or consists of an alloy of one or more of these metals: silver, copper, aluminium; f) and with a corrosion protection layer of nickel or a nickel-containing alloy applied directly to the mirror layer P240421-07Reactor gas system with motor + generator 3 and bordering the reaction chamber. A method and an arrangement for carrying out the process of electrochemically combining hydrogen and oxygen as electrolysis gas with at least one known fuel gas as carrier gas to form a combined gas is described in DE 10 2015 102 998 A1. In document DE 10 2015 102 999 A1, an arrangement for the electrochemical combination of two, three, or more gases to form a compound gas is described, and in document DE 10 2015 103 000 A1, the method for electrochemically combining two, three, or more gases to form a compound gas is described. The invention DE 10 2022 202 398 A1 relates to a method for operating an electrolyzer.for the production of hydrogen and oxygen, comprising an anode compartment and a cathode compartment separated from each other by a membrane impermeable to OH, with at least the following process steps: a) the cathode compartment of the electrolyzer is operated temporarily dry, b) the cathode compartment of the electrolyzer is temporarily at least partially flooded or at least partially humidified, c) wherein the at least partial flooding or at least partial humidification of the cathode compartment of the electrolyzer is effected by metering a liquid medium by means of a metering valve. Furthermore, the invention relates to the use of the process for operating an electrolyzer for the production of hydrogen and oxygen. In addition, WO 2013 / 000580 A2 describes a device for the production of hydrogen by means of electrolysis, comprising a direct current source and pulsed direct current as electrical energy for the electrolysis, as well as an electrode compartment.with pure electrolyte liquid, comprising at least one anode and at least one cathode, which are formed from the same or different electrically conductive, low-resistance material. At least one neutral plate made of oxidation-resistant, electrically conductive material is arranged between each anode and cathode. The mutually facing surfaces of the anode, neutral plate, and cathode have a surface structure with a high surface area (in the form of deep crystalline porosity). The invention relates to a process for the production of hydrogen, which is carried out in the device, as well as preferred uses. The object of the invention is to provide an electric generator system with an internal combustion engine in combination with a reactor system based on an alkaline electrolysis plant for the production of a fuel gas with a high oxygen content from a carrier gas, e.g., natural gas.and / or the exhaust gases of combustion engines, utilizing the hydrogen and oxygen produced during electrolysis, and to provide a process for producing a fuel gas or synthesis gas with a high oxygen content using the reactor, whereby, compared to already known processes and systems, the energy input for producing the fuel gas is significantly reduced and the water input is minimized. Due to a high oxygen content in the fuel gas of over 20 vol%, the energy content of the gas according to the invention is significantly higher than that of mixed gases already used in practice with an oxygen content of less than 5 vol%. By arranging the reactor, including all auxiliary equipment, in a container, largely standardized prefabrication of the reactor and electrolysis system can take place at the manufacturer's facility, ensuring compliance with and installation of appropriate safety devices. This allows for rapid assembly at the end customer's site.possible. In the process for producing a fuel gas with a high oxygen content from the main components methane, hydrogen, and oxygen, an alkaline low-voltage electrolysis plant is used. Unlike conventional reactor gas systems (P240421-07 reactor gas plant with motor and generator 5), the resulting hydrogen and oxygen are not immediately separated. Instead, during electrolysis, the gaseous alkane present in the electrolysis water, e.g., methane or propane, attaches itself to the electrolysis gas bubbles within the individual cells of the reactor housing and forms an atomic compound between the natural gas and the hydrogen and oxygen produced during electrolysis, thus creating a new synthesis gas. The new synthesis gas contains a doubly saturated hydrocarbon. In the resulting compound, H₂ and O₂ are stabilized and possess a new, bound structure in gaseous form with high energy. The new synthesis gas, or fuel gas, can be compressed to a pressure ofThe gas is compressed and then, for example, fed to the burners of furnaces via appropriate pipes. The produced fuel gas has an oxygen content greater than 20% by volume and is flammable but non-explosive. Furthermore, the use of exhaust gases from combustion engines to produce a fuel gas from the main components of combustion engine exhaust, hydrogen, and oxygen is described. The reactor system according to the invention consists, for example, of a 40-foot container containing a reactor with an alkaline electrolysis system, auxiliary system components such as pumps, electrolyte tanks, electrolyte storage, gas storage with corresponding piping, valves, measuring and control technology, operating and safety systems, and optionally a combined gas engine with an electric generator for additional electrical power generation. Special safety devices, such as flashback arrestors, protect against dangerous flashbacks.Backfire prevention devices protect plant components, piping systems, and extraction points against dangerous gas backflow. An additional, smaller container can be set up as a support for the combined gas engine with electric generator and measuring, control, and safety technology. The alkaline electrolysis system integrated into the reactor is a low-voltage system that advantageously operates at 20 V to 30 V (P240421-07 Reactor gas system with motor + generator 6) at 50 A to 60 A and generates no heat during operation, achieving an efficiency of over 90%. The electrodes of the electrolysis system are arranged in a multitude of individual cells, each consisting of a molded plastic body. The molded body is advantageously made of GRP with a lid. The molded plastic body can have a rib on its outer surface to absorb forces. Each individual cell contains a cathode and an anode withIntermediate plates are used between the cathode and anode. Advantageously, 5 to 10 intermediate plates are arranged between the cathode and anode. Increasing the number of intermediate plates increases the performance of the electrolysis system, but at the cost of increased material usage. All plates are preferably made of non-magnetic stainless steel and measure 2 m x 1 m. Smaller plate sizes are also conceivable. The cathodes and anodes are 1 mm thick, and the intermediate plates are 0.6 mm thick. The spacing between plates is 1 mm to 5 mm, advantageously 3 mm. Above 5 mm, the system's efficiency deteriorates. Due to the small spacing and the size of the plates, capillary action is created between them. The intermediate plates act as capacitors. The vertical edges of the plates are spaced apart by plastic elements. Advantageously, all plates are pressed into the individual cells with spacing. The number of individual cells in theThe reactor size is determined by the desired amount of hydrogen and oxygen to be produced, and thus by the desired amount of fuel gas, and can exceed 100 liters. The stainless steel plates have a surface texture. The reactor housing is filled with an alkaline electrolyte up to 80% to 90%. This creates a fuel gas chamber under the ceiling of the reactor housing above the individual cells. The individual cells are completely immersed in a soda solution. Each individual cell has at least one opening on its underside and several openings on its top side. The carrier gas is blown into the individual cells through openings in the lance below each cell via at least one lance serving as the carrier gas supply line. When the electrolysis system is switched on, hydrogen and oxygen are produced. Both gases form an atomic bond within the individual cells.Carrier gas is introduced, producing a synthetic fuel gas with a high oxygen content. The individual cells have support elements on their outer narrow sides, allowing each cell to be braced against a support frame in the reactor housing. Alternatively, the shape of the plastic molded body is designed such that protruding projections on the right and left outer edges act as support elements, allowing the individual cell to be easily suspended in a support frame within the reactor housing. Within the reactor housing, the individual cells are suspended side by side, and each cell has an electrical connection for the cathode and anode. In the wall of the fuel gas chamber of the reactor housing, there are two fuel gas outlets located just below or within the ceiling of the reactor chamber. The first fuel gas outlet is for the discharge of the fuel gas. A second fuel gas outlet allows for the supply or return of fuel gas via a...A pipeline with a gas pump leads to the carrier gas supply at the bottom of the reactor housing. Here, a portion of the gas mixture is added to the carrier gas, allowing it to pass through the reactor again. In practice, it has been found that recirculating 5 to 10% of the generated fuel gas is advantageous. This partial addition of new fuel gas mixes with the carrier gas and has a positive effect on the electrochemical reaction of the carrier gas with the hydrogen and oxygen atoms in the individual cells. The individual cells are flooded with an alkaline solution, preferably a 3% soda solution. Soda solution has the advantage of being less aggressive than other alkalis. A concentration higher than 3% reduces the water content and only has a negative impact on the overall performance. The oxygen and hydrogen gases produced when a voltage is applied are mixed with natural gas in the individual cells.or another carrier gas, such as exhaust gases from combustion engines, electrochemical reactions or gas compounds are formed. The natural gas also contains components of N₂ and CO₂. This results, for example, in the following volume percentage ratios of the individual gas components: methane 30 to 40 vol%, hydrogen 20 to 70 vol%, oxygen 5 to 27 vol%, and the sum of N₂ and CO₂ 1 to 5 vol%. Corresponding tests and investigations of this fuel gas have shown that it is flammable but not explosive. The technical data for the operating system are: inlet volume of CH₄ / C₃H₆ at 1 to 5 L at 20 to 40 mbar, operating pressure in the individual cells at 10 to 100 mbar, and operating and electrolyte temperatures at 10 to 40 mbar. oIn the individual cells, a natural compound of H1-O1-H1 atoms is formed, and from a carrier gas, e.g., CH4, a high-energy and safely controllable synthetic fuel gas with the energy content and safe properties of CH4 is produced via electrochemical reactions. The resulting new synthetic fuel gas is a doubly saturated hydrocarbon. From approximately 1 liter of CH4 per minute and an electrolysis current of approximately 1 kW and approximately 300 liters / hour of H1O1H1, new hydrocarbon molecules consisting of approximately 20 to 30% methane are structured in the system. 70 to 80% of the electrolysis gas molecules then bind to these molecules, thus forming the finished synthesis gas or fuel gas. An electrolyte storage tank is advantageously arranged next to the reactor housing. The electrolyte storage tank has an external electrolyte supply line and at least one electrolyte pipeline with a shut-off valve and pump between the reactor housing and the electrolyte storage tank.A gas engine is mechanically connected to an electric generator in a separate container or adjacent to the reactor housing. The gas engine is connected via a P240421-07 reactor gas system with engine and generator 9 piping for mixed gas to the gas chamber of the reactor housing, which serves as the energy supply for the gas engine. An exhaust gas collection device is provided on the gas engine, which connects directly to the carrier gas supply line and / or via a separate electrolyte tank. This tank has a piping connection to the reactor housing and a piping connection to the electrolyte storage tank with appropriate valves. This allows the exhaust gas to be routed directly to the reactor housing and used there as a carrier gas. The exhaust gas is cleaned in the electrolyte tank and electrolyte storage tank. The container houses the corresponding measurement, control, and safety equipment, including the electrical installation.The invention described above will be explained in more detail below using an exemplary embodiment. The accompanying drawings show, in Fig. 1, the basic structure of the reactor system with electrolysis unit in the reactor housing, an electrolyte storage tank, a gas storage tank, and a gas engine with electric generator as a power generation system, and the corresponding pipeline connections with valves and pumps in a container; Fig. 2 a cross-section through a reactor housing with a side view of a single cell, the electrolyte level, and the gas space above it; Fig. 3 a longitudinal section through a container showing the arrangement of some of the single cells with the indicated carrier gas supply to the single cells and the outlet of the mixed gas, and the suspension of the single cells in the reactor housing; and Fig. 4 the section through a single cell with a molded plastic body, cathode, anode, and three intermediate plates.5.

An alkaline electrolysis system 3, consisting of a plurality of individual cells 4, is installed in a reactor housing 2 of a 40-foot container 1. This electrolysis system 3 advantageously operates as a low-voltage system at 30 V. However, voltage values ​​between 5 V and 400 V are also conceivable. No heat is generated during the operation of the electrolysis system 3. The efficiency of this system according to the invention is over 90%. The electrodes of the electrolysis system 3 consist of non-magnetic, preferably surface-structured, stainless steel plates 6 with a size of 2 m x 1 m. Smaller dimensions are also conceivable. The stainless steel plates 6 as cathode 6.1 and anode 6.2 preferably have a thickness of 1 mm and the intermediate plates 6 located between the cathode 6.1 and anode 6.2.The individual cells 4 are the same size as the cathode 6.1 and anode 6.2, but with a thickness of 0.6 mm. In the reactor housing 2, the individual cells 4 are suspended parallel to each other on a support frame 30 and are completely immersed in the electrolyte 8. A 3% sodium chloride solution is preferably used as the electrolyte 8. Each individual cell 4 consists of a molded plastic body 5 with a lid 5.1, which is firmly welded to the molded plastic body 5. The molded plastic body 5 advantageously has a kind of band around its outer circumference to reliably absorb any pressure that may arise in the individual cells during electrolysis. The cathode 6.1, the anode 6.2, and intermediate plates 6.3 are pressed into this molded plastic body 5. The number of intermediate plates 6.3 varies between two and twenty. The intermediate plates 6.3 function as capacitor plates.In practice, three or up to five intermediate plates 6.3 have proven advantageous. All plates 6 are securely spaced from one another by plastic elements 7. The plastic elements 7 are arranged continuously along the height of the plates 6 only on the narrow sides. Plastic elements 7 are provided only at intervals on the underside and top side of the plates 6. The plastic molded body 5 of each individual cell 4 has at least one opening on its narrow underside for the inflow of the carrier gas 11 and several openings on its narrow top side for the outlet of the resulting synthetic fuel gas 25 from the individual cell 4. Electrical connections 28 for the cathode 6.1 and anode 6.2 are provided on each individual cell 4. The reactor housing 2 is filled to 80% to 90% with the alkaline electrolyte 8 and floods all individual cells 4. Thus, a fuel gas space 9 exists under the ceiling of the reactor housing 2.In this fuel gas chamber 9, a first fuel gas outlet 10 is provided for the discharge and further use of the fuel gas 25 as fuel gas 25. A carrier gas supply line 11 is also provided at the bottom of the reactor housing 2, wherein this carrier gas supply line 11 is provided within the reactor housing 2 from the first individual cell 4 to the last individual cell 4 in the form of at least one lance 12 with outlet openings below the plurality of individual cells 4. In addition to the first fuel gas outlet 10, a further, a second fuel gas outlet 13 is advantageously provided, which forms a connection to the carrier gas supply line 11 via a pipeline 14 for fuel gas 25, and a gas pump 15 is integrated in this pipeline 14. Through this pipeline 14, a portion of the generated fuel gas 25 is returned to the carrier gas supply line 11 and again passed through the reactor housing 2.The fuel gas 25, which is passed through the reactor housing 2 again, fluctuates between 5 and 10% of the total fuel gas 25 produced and positively influences the new fuel gas production. An electrolyte storage tank 16 can be arranged next to the reactor housing 2. At least one electrolyte pipeline 17 with a shut-off valve 18 and a pump 29 is provided between the reactor housing 2 and the electrolyte storage tank 16. The electrolyte storage tank 16 has an electrolyte supply line 19. Furthermore, a gas storage tank 27 can be arranged in the container 1. The gas storage tank 27 has a supply line 14 from the first mixed gas outlet 10 via a gas pump 15 and valve 18 and a P240421-07 reactor gas system with motor and generator 12, and a discharge for the mixed gas 25. Next to the reactor housing 2 or in an additional container 1, a gas engine 20 can be mechanically coupled to an electric generator 21.The gas engine 20 has a connection via a pipeline 14 for fuel gas 25 from the fuel gas chamber 9 of the reactor housing 2, serving as the energy supply for the gas engine 20. An exhaust gas collection device is provided on the gas engine 20, which has a pipeline 22 directly to the carrier gas supply line 11. Furthermore, a pipeline connection via a valve 18 is provided to a separate electrolyte tank 23. The electrolyte tank 23 has a pipeline to the pipeline 22, which leads to the reactor housing 2, and a pipeline 24, which connects to the electrolyte storage tank 16 via corresponding valves 18. The fuel gas 25 is routed via the first fuel gas outlet 10, e.g., to a furnace in a glass plant. Special safety devices 26, such as flashback arrestors, are installed in the container 1 to protect against dangerous flashbacks and fires.Gas backflow preventers serve to protect plant components, pipelines 14, and extraction points against dangerous gas backflow. The reactor system, with its measurement and control technology 26, including safety technology 26 and electrical installation 28 for individual components of the reactor system, is installed in container 1 or in an additional container 1. The process for producing a mixed gas from a carrier gas 11 and hydrogen and oxygen produced by an electrolysis plant 3, using a reactor, takes place by introducing, for example, natural gas 11 from the local gas network or another carrier gas 11, e.g., C3H8, biogas 11, or exhaust gases from combustion engines 11, into the reactor housing 2 via the carrier gas supply line 11, whereby, for example, 100 m³ is introduced via a valve 18. 3Natural gas 11 is fed into the reactor housing 2 below the individual cells 4 at a rate of 200 kW / h. The reactor gas system with motor and generator 13 supplies the electrolysis plant 3 with 200 kW / h of electrical energy. The incoming natural gas 11 between the plates 6 of the electrolysis plant 3 in the individual cells 4 forms atomic compounds with the split hydrogen and oxygen atoms from the soda-water solution 8, thus forming a fuel gas 25 within the individual cells 4. Above the electrolyte 8 in the reactor housing 2, the fuel gas 25 collects in the fuel gas chamber 9 at a rate of 200 m³ / h, according to both specified connection values. With an increase in the amount of natural gas supplied and the electrical connection values, the amount of fuel gas 25 produced increases linearly. The CO₂ from the soda (Na₂CO₃) is broken down and used for the new synthetic gas.From the fuel gas chamber 9, a portion of the fuel gas 25 is routed via the first fuel gas outlet 10 to the burners of an end user, and a portion of the fuel gas 25, approximately 5 to 10% of the total fuel gas 25 produced, is routed via the second fuel gas outlet 13 and the pipeline 14 from the fuel gas chamber 9 to the carrier gas supply line 11. In the carrier gas supply line 11 and the lance 12, the fuel gas 25 mixes with the carrier gas 11 and is then passed through the plates 6.1, 6.2, and 6.3 of the individual cells 4 of the electrolysis unit 3. Here, the fuel gas 25 from the fuel gas chamber 9, together with the carrier gas 11, forms atomic compounds with the hydrogen and oxygen. The fuel gas 25, which is routed from the fuel gas chamber 9 via the second fuel gas outlet 13, causes a quality adjustment to the carrier gas 11. In practice, it has been found that without the partial recirculation of the generated fuel gas 25, the quality of the fuel gas 25 decreases and the generated fuel gas 25 becomes more aggressive.The fuel gas 25 from the second fuel gas outlet 13 thus passes through the electrolysis plant 3 several times. The new inventive process utilizes the electrolysis gas consisting of H1-O1-H1 atoms and a carrier gas 11, e.g., CH4 or C3H8, and additionally the exhaust gases of one or more combustion engines, the hydrocarbons and carbon dioxides contained therein, to structure an energy-rich and safely controllable synthetic fuel gas 25 with the energy content and safe properties of CH4 or C3H8 by means of electrochemical reactions. From approximately 1 L per minute of CH4 and an electrolysis current of approximately 1 kW, approximately 300 L / h of H1O1H1 are produced and structure new hydrocarbon molecules in the individual cells 4 of the reactor, which consist of approximately 20 to 30% methane, to which 70 to 80% electrolysis gas molecules then dock, thus forming the new synthetic fuel gas 25.In contrast to previously carried out alkaline water electrolysis processes, the process according to the invention does not separate the generated hydrogen and oxygen. Through the controlled enrichment of the electrolysis water with a gaseous alkane, this hydrocarbon couples to the resulting electrolysis gas bubbles in such a way that a new synthesis gas is formed within the individual cell. In this process, the CO3 from the soda is also decomposed and used for the production of the new synthesis gas. The mixed gas 25 produced by the electrolysis plant 3, when using natural gas 11 as the carrier gas 11, has a mixture volume with the following gas proportions: methane 30 to 40 vol%, hydrogen 1 to 70 vol%, oxygen 1 to 27 vol%, and nitrogen. 2,CO2 and other gas components 0 to 5 vol-%. The fuel gas 25 to be supplied to the end user can be further compressed to a pressure of 0.5 to 1 bar. If a gas engine 20 with a coupled electric generator 21 is present, the gas engine 20 can be supplied with gas via a supply line 14 from the first fuel gas outlet 10 and a valve 18. The exhaust gases of the gas engine 20 can, as already described above, be fed directly to the carrier gas supply line 11 or routed via an electrolyte tank 23 to the carrier gas supply line 11 and / or via a pipeline 24 to an electrolyte storage tank 16. In the electrolyte container 23 and the electrolyte storage tank 16, the exhaust gases of the gas engine 20 are cleaned and the exhaust gases P240421-07 reactor gas system with engine + generator 15 partially form atomic compounds with the electrolyte.
