[0003] Although the technology for producing aviation fuel through biomass gasification is relatively mature and can meet the demand for aviation fuel to some extent, it is still difficult to achieve continuous and large-scale production of aviation fuel due to limitations in raw material supply, production costs, and production efficiency.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the accompanying drawings, the size of constituent elements, the thickness of layers, or areas may sometimes be exaggerated for clarity. Therefore, any implementation of this application is not necessarily limited to the dimensions shown in the drawings, and the shapes and sizes of components in the drawings do not reflect true proportions. Furthermore, the drawings schematically illustrate ideal examples, and any implementation of this application is not limited to the shapes or values ​​shown in the drawings.

[0025] In recent years, with the increasing global awareness of environmental protection, renewable energy sources such as solar and wind power have attracted much attention due to their clean and environmentally friendly characteristics, and their demand has been growing accordingly. However, the inherent characteristics of these renewable energy sources, such as intermittency, periodicity, and volatility, have brought unprecedented challenges to the stable production of aviation fuel.

[0026] As a significant source of carbon emissions, the aviation industry's decarbonization process is particularly crucial. However, due to the industry's characteristics, it cannot achieve complete decarbonization through electrification like other sectors. Therefore, developing sustainable aviation fuels has become an inevitable choice for the aviation industry to achieve a green transformation.

[0027] Currently, the technology for producing aviation fuel from biomass gasification is relatively mature and can meet the demand for aviation fuel to a certain extent. However, this technology still faces many challenges in practical applications, especially the difficulty in achieving continuous production of aviation fuel. This is mainly due to factors such as the unstable supply of biomass raw materials, high production costs, and low production efficiency.

[0028] Therefore, ensuring a stable supply of aviation fuel while achieving its green and sustainable production has become a critical technical challenge for the aviation industry. This requires not only in-depth research into stable renewable energy utilization technologies, but also the exploration of more efficient and economical biomass gasification processes, as well as the development of new sustainable aviation fuel synthesis methods to meet the dual demands of the aviation industry's rapid development and carbon emission targets.

[0029] In view of the problems existing in the prior art, this application provides an aviation fuel preparation system, see [link to relevant documentation]. Figure 1 The system includes: Energy storage device 1, electrolysis device 2, gasification device 3, reaction device 4, and blender 6; The energy storage device 1 is connected to the electrolysis device 2, and the energy storage device 1 is configured to supply power to the electrolysis device 2. The electrolysis device 2 is connected to the gasification device 3 and the reaction device 4. The electrolysis device 2 is configured to electrolyze water to obtain oxygen and hydrogen, and deliver the oxygen to the gasification device 3 and the hydrogen to the reaction device 4. The gasification device 3 is configured to cause the oxygen to react with the gasification material to obtain gasification products. The reaction device 4 is connected to the gasification device 3, and the reaction device 4 is configured to react the gasification product with the hydrogen to obtain an organic product. The blender 6 is connected to the reaction device 4, and the blender 6 is configured to mix the organic product with petroleum-based jet fuel to obtain aviation fuel.

[0030] After the energy storage device 1 supplies power to the electrolysis device 2, water electrolysis is performed in the electrolysis device 2 to produce hydrogen and oxygen. Oxygen participates in the gasification reaction as a gasifying agent, and the gasified material can be biomass, etc. The gasification products are carbon monoxide, hydrogen, carbon dioxide, etc. After the gasification products react with hydrogen, aromatic hydrocarbons of C6-11 composition can be obtained, which can be used to form aviation fuel.

[0031] In practice, electrical energy is stored in a storage device and then transmitted to an electrolysis unit 2. Water is introduced into the electrolysis unit 2 to electrolyze the water, producing oxygen and hydrogen. The oxygen is then transmitted to a gasification unit 3, where the gasified material reacts with the oxygen to form gasification products. These gasification products are then transmitted to a reaction unit 4. Simultaneously, hydrogen produced in the electrolysis unit 2 is transmitted to the gasification unit 3, where it reacts with the gasification products to undergo an aromatics synthesis reaction, yielding organic products. These organic products and petroleum-based aviation kerosene are then transmitted to a blender 6, where they are blended to obtain aviation fuel.

[0032] The electricity stored in the energy storage device 1 can be supplied by wind power, photovoltaic power, or thermal power. In some embodiments, the electrical energy stored in the energy storage device 1 is generated from renewable energy sources, such as wind power and solar power.

[0033] In this application, the energy storage device 1 uses renewable energy (such as solar energy, wind energy, etc.) as the source of electricity. Even when the supply of renewable energy is insufficient or unstable, it can provide the required heat to the reaction device, overcoming the inherent characteristics of renewable energy (such as wind energy, solar energy) such as intermittency, periodicity and volatility, and ensuring the continuity and stability of the reaction process.

[0034] In practice, the system can primarily rely on wind and solar power, both of which are renewable energy sources that help reduce carbon emissions and meet the requirements of green transformation. However, in cases where wind and solar resources are insufficient or unstable, the system can switch to thermal power generation as a supplement to ensure the stability and continuity of power supply, thereby guaranteeing the continuous production of aviation fuel.

[0035] In some implementation schemes, see Figure 1 The electrolysis device 2 includes an anode 21, a cathode 22, an electrolytic cell 23, an oxygen storage tank 24, and a hydrogen storage tank 25. The anode 21 and the cathode 22 are both disposed within the electrolytic cell 23. The anode 21 is connected to the oxygen storage tank 24, and the cathode 22 is connected to the hydrogen storage tank 25. The oxygen storage tank 24 is connected to the gasification device 3 and is configured to receive and store the oxygen, and to transport the oxygen to the gasification device 3. The hydrogen storage tank 25 is connected to the reaction device 4 and is configured to receive and store the hydrogen, and to transport the hydrogen to the reaction device 4.

[0036] Specifically, the electrolytic cell 23 is connected to the energy storage device 1, which supplies power to the electrolytic cell 23.

[0037] The inlet of the oxygen storage tank 24 is connected to the anode 21, and the outlet is connected to the gasification device 3. Specifically, the outlet is connected to the inlet of the gasification reactor 31.

[0038] The inlet of the hydrogen storage tank 25 is connected to the cathode 22, and the outlet is connected to the reaction device 4. Specifically, the outlet is connected to the first reactor 41 and the second reactor 42 respectively.

[0039] In practice, the energy storage device 1 supplies power to the electrolyzer 23 to carry out the electrolysis of water, thereby obtaining oxygen at the anode 21 and hydrogen at the cathode 22. The oxygen is then transported to the oxygen storage tank 24 for storage, and the hydrogen is transported to the hydrogen storage tank 25 for storage.

[0040] In this application, by setting the electrolyzer 23 as the core component for water electrolysis, the electrolysis process can be controlled more effectively, and the electrolysis efficiency can be improved. The setting of the oxygen storage tank 24 and the hydrogen storage tank 25 enables the effective separation and storage of the oxygen and hydrogen produced by electrolysis, which not only avoids the safety hazards caused by gas mixing, but also ensures that the gasification device 3 and the reaction device 4 can obtain a stable gas supply when needed.

[0041] Oxygen storage tank 24 and hydrogen storage tank 25 also serve as buffer devices to cope with gas fluctuations produced by electrolysis unit 2, ensuring the stability of gas supply for gasification unit 3 and reaction unit 4.

[0042] In some embodiments, the electrolytic cell 23 is any one of an alkaline electrolytic cell, a proton exchange membrane electrolytic cell, and a solid oxide electrolytic cell.

[0043] An alkaline electrolyzer is a device that converts electrical energy into chemical energy through electrochemical reactions. Its core function lies in the oxidation-reduction reaction of ions in the electrolyte solution under the influence of an electric field, resulting in chemical changes at the anode and cathode. Water molecules gain electrons at the cathode to form hydrogen gas and hydroxide ions. These hydroxide ions pass through a diaphragm to the anode, where they are converted into oxygen and water under voltage. The electrodes are made of nickel mesh or nickel foam, and their performance has a decisive influence on the current density and electrolysis efficiency. The diaphragm, located between the cathode and anode plates, acts as a barrier against hydrogen and oxygen while allowing electrolyte ions to pass through. The diaphragm needs to be resistant to corrosion from high-concentration alkaline solutions and possess good mechanical strength.

[0044] A proton exchange membrane (PEM) electrolyzer is an electrochemical separation technology that utilizes ion exchange membranes. In the electrolyzer, the positive and negative electrodes are placed at opposite ends, with the proton exchange membrane positioned in the middle. When an electrolyte is added to the electrolyzer and an ion exchange is applied, cations and anions exchange on the proton exchange membrane, thus achieving ion separation and purification. The proton exchange membrane is the core component of the PEM electrolyzer, exhibiting selective permeability and allowing only specific ions to pass through. The electrodes are made of noble metals (such as platinum or iridium) or composite materials coated with noble metals to improve electrolysis efficiency and stability.

[0045] Solid oxide electrolyzers are highly efficient energy conversion devices. Their core principle lies in using electrolysis to decompose water molecules, producing hydrogen and oxygen. During electrolysis, when a certain voltage is applied to the electrolyzer, water molecules gain electrons at the cathode and are decomposed into hydrogen and hydroxide ions. Subsequently, the hydroxide ions migrate through the electrolyte layer to the anode, where they release electrons and oxygen. The electrons then return to the cathode through an external circuit, forming an electric current. The electrolyte is made of a solid oxide material with ionic conductivity, such as yttrium-stabilized zirconium oxide (YSZ). The anode and cathode are coated on both sides of the electrolyte, forming the three-layer structure required for the electrolysis reaction.

[0046] In this application, the alkaline electrolyzer uses inexpensive and readily available materials, such as potassium hydroxide, resulting in significant cost-effectiveness. The proton exchange membrane electrolyzer, with its high efficiency and fast response time, helps improve the energy efficiency and production speed of the entire preparation system. The solid oxide electrolyzer, operating at high temperatures, helps accelerate reaction kinetics and improve hydrogen production efficiency; both are suitable for the electrolytic hydrogen production described in this application.

[0047] In some implementation schemes, see Figure 1 The gasification device 3 includes a gasification reactor 31, a carbon monoxide storage tank 32, and a carbon dioxide storage tank 33.

[0048] The gasification reactor 31 is connected to the electrolysis device 2, and the gasification reactor 31 is used to receive oxygen output from the electrolysis device 2 and carry out a gasification reaction.

[0049] The gasification reactor 31 is connected to both the carbon monoxide storage tank 32 and the carbon dioxide storage tank 33. Specifically, the outlet of the gasification reactor 31 is connected to an outlet pipe 311, the end of which, away from the gasification reactor 31, is connected to both the carbon monoxide storage tank 32 and the carbon dioxide storage tank 33. The carbon monoxide storage tank 32 is configured to store the carbon monoxide in the gasification products and transport it to the reaction apparatus 4. The carbon dioxide storage tank 33 is configured to store the carbon dioxide in the gasification products and transport it to the reaction apparatus 4.

[0050] In practice, the gasification reactor 31 is connected to the anode 21 of the electrolysis device 2 to deliver oxygen to the gasification reactor 31.

[0051] The gas outlet pipe 311 may include a main gas pipe and two branch pipes, wherein one end of the main gas pipe is connected to the gasification reactor 31 and the other end is connected to one end of each of the two branch pipes, and the ends of the two branch pipes away from the main gas pipe are respectively connected to the carbon monoxide storage tank 32 and the carbon dioxide storage tank 33.

[0052] In practice, oxygen generated at the anode 21 of electrolysis unit 2 is transported to gasification reactor 31, where it reacts with the gasified material to produce gasification products. The gasification products are transported via outlet pipeline 311, with carbon monoxide in the gasification products being stored in carbon monoxide storage tank 32 and carbon dioxide in the gasification products being stored in carbon dioxide storage tank 33. Before the reaction, the raw material gas from carbon monoxide storage tank 32 or carbon dioxide storage tank 33 is first transported to reaction unit 4, where carbon monoxide or carbon dioxide reacts with hydrogen in an aromatics synthesis reaction to obtain organic products.

[0053] In practice, carbon monoxide can first be transported from carbon monoxide storage tank 32 to reaction device 4, while hydrogen is also transported to reaction device 4. The carbon monoxide and hydrogen undergo an aromatic synthesis reaction to obtain some organic products. Then, carbon dioxide is transported from carbon dioxide storage tank 33 to reaction device 4, while hydrogen is also transported to reaction device 4. The carbon dioxide and hydrogen undergo an aromatic synthesis reaction to obtain another portion of organic products.

[0054] In this application, by setting up a carbon monoxide storage tank 32 and a carbon dioxide storage tank 33, carbon monoxide and carbon dioxide in the gasification products can be stored respectively, so that the gasification products can be utilized more effectively and the waste of useful resources can be avoided.

[0055] Carbon monoxide and carbon dioxide are different reactants, and the reaction conditions are different in the subsequent synthesis of organic products. By storing and transporting them to reaction device 4, the reaction conditions can be flexibly adjusted according to actual needs, thereby optimizing the final synthesis process of aviation fuel.

[0056] By storing carbon monoxide and carbon dioxide from the gasification products separately, the system has more room for adjustment when faced with unstable gasification feedstock supply or fluctuations in gasification reaction conditions. For example, when insufficient gasification feedstock supply leads to a reduction in gasification products, the stored carbon monoxide can be used preferentially for the synthesis of organic products to maintain production continuity.

[0057] In some implementations, a separation device may be installed on the gas outlet line 311. The inlet of the separation device is connected to the gasification reactor 31, and the outlet is connected to the carbon monoxide storage tank 32 and the carbon dioxide storage tank 33, respectively.

[0058] In practice, the gasification products in the gasification reactor 31 first enter the separation device for separation along the gas outlet pipeline 311. After separation, carbon monoxide and carbon dioxide are obtained, and then the carbon monoxide and carbon dioxide are respectively transported to the carbon monoxide storage tank 32 and the carbon dioxide storage tank 33.

[0059] In this application, by setting up a separation device, the gasification products can be separated more efficiently to obtain pure carbon monoxide and carbon dioxide.

[0060] In some implementation schemes, see Figure 1The reaction apparatus 4 includes a first reactor 41 and a second reactor 42. Both the first reactor 41 and the second reactor 42 are connected to the electrolysis apparatus 2. The first reactor 41 is connected to the carbon monoxide storage tank 32, and the second reactor 42 is connected to the carbon dioxide storage tank 33. The first reactor 41 is configured to react carbon monoxide with hydrogen to generate a first organic compound. The second reactor 42 is configured to react carbon dioxide with hydrogen to generate a second organic compound. The first organic compound and the second organic compound constitute the organic product.

[0061] Specifically, both the first reactor 41 and the second reactor 42 are connected to the cathode 22 of the electrolysis device 2.

[0062] Both the first and second organic compounds are C. 1-12 Organic matter in the components.

[0063] In specific implementation, hydrogen is delivered to the first reactor 41 and the second reactor 42 respectively, while carbon monoxide is delivered from the carbon monoxide storage tank 32 to the first reactor 41 and carbon dioxide is delivered from the carbon dioxide storage tank 33 to the second reactor 42. The first reactor 41 and the second reactor 42 can carry out aromatic synthesis reaction simultaneously. After the reaction, a first organic compound is generated in the first reactor 41 and a second organic compound is generated in the second reactor 42. The first organic compound and the second organic compound are mixed to form an organic product.

[0064] In this application, by setting up a first reactor 41 and a second reactor 42, carbon monoxide and carbon dioxide are simultaneously reacted with hydrogen to generate a first organic compound and a second organic compound, respectively, thereby improving the production efficiency of aviation fuel. Furthermore, since the first reactor 41 and the second reactor 42 can be optimized according to different reaction conditions, organic products with different chemical structures and properties can be generated. These organic products, when mixed with petroleum-based aviation kerosene, can form a more stable and efficient aviation fuel, thereby improving its quality.

[0065] The first reactor 41 and the second reactor 42 can operate independently or in coordination to adapt to different production needs and raw material supply conditions. For example, when the biomass feedstock supply is sufficient, carbon monoxide can be used preferentially for the reaction. When the biomass feedstock supply is insufficient, stored carbon dioxide can be used for the reaction to ensure the continuous production of aviation fuel.

[0066] In some implementation schemes, see Figure 1 The blender 6 can be connected to the first reactor 41 and the second reactor 42 respectively. The blender 6 is used to mix the first organic matter, the second organic matter, and petroleum-based jet fuel.

[0067] In specific implementation, the first organic matter output from the first reactor 41 is transported to the blender 6, and the second organic matter output from the second reactor 42 is transported to the blender 6. In the blender 6, organic products with different C components can be fully mixed with petroleum-based jet fuel, and the mixed product is output as aviation fuel.

[0068] In some implementation schemes, see Figure 1 The system further includes a distillation unit 5, the inlet of which is connected to the reaction device 4, and the outlet of which is connected to the blender 6. Specifically, the inlet of the distillation unit 5 is connected to the first reactor 41 and the second reactor 42, respectively. In some embodiments, the distillation unit 5 is a distillation column.

[0069] In practice, the first organic matter output from the first reactor 41 and the second organic matter output from the second reactor 42 are both sent to the distillation unit 5 for distillation. The distillation products are then sent to the blender 6 for thorough mixing. The mixed products are then output as aviation fuel.

[0070] In practice, the products from the first reactor 41 and the second reactor 42 can be transported together to the distillation unit 5 for distillation, or the products produced first can be transported to the distillation unit 5 for distillation.

[0071] In this application, by setting up a distillation unit 5, the first organic matter and the second organic matter output from the first reactor 41 and the second reactor 42 can be deeply separated and purified, effectively removing impurities and unreacted substances from the organic matter, thereby improving the purity and quality of the final aviation fuel. High-purity aviation fuel not only improves combustion efficiency and reduces emissions, but also extends the service life of aircraft engines and reduces maintenance costs.

[0072] In some implementation schemes, see Figure 1 The energy storage device 1 is connected to the reaction device 4; the energy storage device 1 is configured to provide heat to the reaction device 4. In some embodiments, the reaction temperature in the reaction device 4 is 300 °C to 400 °C.

[0073] In practice, the reaction device 4 may be equipped with an electric heater, an electric heating tube, etc., which are connected to the energy storage device 1.

[0074] In some implementation schemes, see Figure 1 The energy storage device 1 is connected to the gasification device 3; the energy storage device 1 is also configured to provide heat to the gasification device 3. Specifically, the energy storage device 1 is connected to the gasification reactor 31 to heat the gasification reactor 31. In some embodiments, the temperature of the gasification reaction is 800 °C to 1000 °C.

[0075] In practice, an electric heating device, such as an electric arc heater or an electric heating tube, can be installed on the gasification device 3; specifically, a heating device can be installed on the gasification reactor 31 to heat the gasification reactor 31.

[0076] In this application, the energy storage device 1 is not only used to supply power to the electrolysis device 2, but is also configured to heat the gasification device 3. This reduces the system's dependence on external heat sources (such as heat generated by fossil fuel combustion), enhances the system's independence and reliability, and allows the system to more flexibly respond to the volatility and intermittency of renewable energy. When renewable energy supply is insufficient, the energy storage device 1 can release stored electrical energy to heat the gasification device 3, ensuring the continuous operation of the gasification reaction and thus maintaining stable aviation fuel production.

[0077] In some embodiments, the electrolysis device 2 is connected to the reaction device 4 to react oxygen with the carbonized catalyst to obtain a regenerated catalyst.

[0078] During the reaction in reaction device 4, the catalyst used will gradually accumulate carbon, leading to catalyst deactivation. At this time, some of the oxygen generated by electrolysis device 2 can be transported to reaction device 4 to react with the carbonized catalyst to obtain a regenerated catalyst, which can restore the catalyst's activity and be recycled in the reaction device for aromatic synthesis reaction, realizing multi-level utilization of resources and improving resource utilization rate.

[0079] In some implementations, the gasification material is any one of coal, kitchen grease, agricultural and forestry waste, and solid waste.

[0080] In this application, coal, kitchen waste oil, agricultural and forestry waste, and solid waste are converted into aviation fuel through gasification. This not only achieves efficient resource utilization but also reduces environmental pollution, aligning with the concepts of circular economy and green development. It also reduces dependence on a single raw material, mitigating the impact of raw material shortages or price fluctuations on production.

The system includes: an energy storage device 1, an electrolysis device 2, a gasification device 3, a reaction device 4, a distillation device 5 (specifically a distillation column), and a blender 6. The electrolysis device 2 includes an anode 21, a cathode 22, an electrolytic cell 23 (specifically a proton exchange membrane electrolytic cell 23), an oxygen storage tank 24, and a hydrogen storage tank 25. The anode 21 and the cathode 22 are both located within the electrolytic cell 23. The anode 21 is connected to the oxygen storage tank 24, and the cathode 22 is connected to the hydrogen storage tank 25. The gasification device 3 includes a gasification reactor 31, a carbon monoxide storage tank 32, and a carbon dioxide storage tank 33. The outlet of the gasification reactor 31 is connected to an outlet pipe 311, and the end of the outlet pipe 311 away from the gasification reactor 31 is connected to the carbon monoxide storage tank 32 and the carbon dioxide storage tank 33, respectively. The reaction device 4 includes a first reactor 41 and a second reactor 42.

[0088] The energy storage device 1 is connected to the electrolytic cell 23 and the gasification reactor 31. The oxygen storage tank 24 is connected to the gasification reactor 31, and the hydrogen storage tank 25 is connected to the reaction device 4. The carbon monoxide storage tank 32 is connected to the first reactor 41, and the carbon dioxide storage tank 33 is connected to the second reactor 42. The inlet of the distillation device 5 is connected to the reaction device 4, and the outlet of the distillation device 5 is connected to the blender 6.

[0089] Specifically, the process of preparing aviation fuel using the above system is as follows: (1) Power is supplied to the energy storage device 1 by photovoltaic power generation and wind power generation. The energy storage device 1 transmits the stored electricity to the proton exchange membrane electrolyzer 23. After the proton exchange membrane electrolyzer 23 is powered on, it begins to electrolyze water, producing oxygen at the anode 21 and hydrogen at the cathode 22. (2) Oxygen is transported to oxygen storage tank 24 for storage, and hydrogen is transported to hydrogen storage tank 25 for storage; (3) The oxygen is then transported to the gasification reactor 31 along the oxygen storage tank 24. The power storage device 1 supplies power to the gasification reactor 31. The gasification reactor 31 converts electrical energy into heat energy. The oxygen is used as a gasification agent and reacts with the solid waste in the gasification reactor 31 at a temperature of 850 °C to produce hydrogen, carbon monoxide and carbon dioxide. The carbon monoxide is transported to the carbon monoxide storage tank 32 along the gas outlet pipe 311, and the carbon dioxide is transported to the carbon dioxide storage tank 33 along the gas outlet pipe 311. (4) Carbon monoxide is discharged from carbon monoxide storage tank 32 into the first reactor 41, and carbon dioxide is discharged from carbon dioxide storage tank 33 into the second reactor 42. At the same time, hydrogen generated by cathode 22 is transported to the first reactor 41 and the second reactor 42 respectively, so that hydrogen reacts with carbon monoxide in the first reactor 41 to carry out an aromatic synthesis reaction, and hydrogen reacts with carbon dioxide in the second reactor 42 to carry out an aromatic synthesis reaction. The first organic product is obtained in the first reactor 41 and the second organic product is obtained in the second reactor 42. (5) The first organic product and the second organic product are transported to the distillation column for distillation treatment. The distillation product is transported to the blender 6 to fully mix the first organic product, the second organic product and petroleum-based aviation fuel. The resulting mixture constitutes aviation fuel. The resulting aviation fuel contains C 7-16 The components are organic mixtures.

[0090] In summary, this application provides an aviation fuel production system that utilizes water electrolysis to store electricity generated from renewable energy sources (such as solar and wind power) in an energy storage device. This electricity is then used to produce hydrogen and oxygen through water electrolysis, effectively utilizing renewable energy and converting it into hydrogen energy, providing a stable source of raw materials for subsequent aviation fuel production. The oxygen produced through water electrolysis participates in the gasification process, improving gasification efficiency and product quality, reducing dependence on specific biomass feedstocks, and enhancing the diversity and availability of raw materials. Simultaneously, this process achieves a closed-loop conversion from renewable energy to aviation fuel, reducing carbon emissions and enhancing the sustainability of the entire production process. This provides the aviation industry with a green and sustainable fuel production method, contributing to the decarbonization process of the aviation industry, reducing greenhouse gas emissions, and aligning with global climate change response strategies and the long-term development goals of the aviation industry.
