Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalytic chemistry technology, specifically to an ionization-coupled artificial photosynthesis reaction device and reaction system. Background Technology
[0002] The reduction of carbon dioxide (CO2) has long been a research hotspot in the field of green chemistry worldwide. Most existing methods require substantial energy input, such as through high-temperature, high-pressure conditions or electrolysis, which not only increases operating costs but may also indirectly lead to greater carbon emissions.
[0003] Converting CO2 into useful chemicals or fuels is a non-spontaneous process, typically requiring additional energy to overcome this barrier. During reduction, multiple byproducts are often generated in addition to the target product. For example, in the electrocatalytic reduction of CO2, formic acid, carbon monoxide, ethylene, and other compounds may be generated simultaneously, and the proportions of these byproducts are difficult to control precisely. To achieve efficient conversion, precious metals are sometimes used as catalysts, which not only increases costs but may also lead to resource shortages. Furthermore, after prolonged operation, the catalyst surface is prone to carbon buildup or being covered by other contaminants, resulting in decreased activity and consequently reduced product selectivity and yield.
[0004] Developing efficient catalysts and maintaining the necessary reaction conditions (such as temperature and pressure) both incur high costs. Furthermore, equipment maintenance and energy consumption are significant economic burdens. Many CO2 reduction technologies involve multi-step reaction pathways, requiring complex equipment and precise operating conditions. This not only increases the technical difficulty but also raises the risk of system failure. Moreover, some reduction technologies may produce harmful byproducts or emit other greenhouse gases, such as nitric oxide (NOx) and volatile organic compounds (VOCs), posing new threats to the environment.
[0005] For the reasons mentioned above, chemicals or fuels produced by CO2 reduction often do not have a price advantage in the market and are difficult to compete with fossil fuels or other traditional chemical products.
[0006] Therefore, a technical solution is needed that can reduce the requirements for reaction conditions and improve the utilization efficiency of reactants and catalysts. Utility Model Content

[0044] In recent years, the reduction of CO2 has been a research hotspot in the global field of green chemistry. Most existing methods require a large amount of energy input, such as high-temperature catalytic reactions, which usually require high temperature and high pressure conditions, and have low reaction efficiency and selectivity.
[0045] Plasma technology is considered a low-temperature, high-efficiency method for gas ionization, capable of promoting the activation and decomposition of H2 molecules. However, pure plasma reactions often suffer from low energy utilization and poor product selectivity. While catalysts can improve reaction selectivity and efficiency, their activation of reactants is limited in certain situations. Therefore, combining plasma ionization with catalysts holds promise for overcoming the shortcomings of each, achieving highly efficient and energy-saving chemical reaction processes.
[0046] This utility model relates to an ionization-coupled artificial photosynthesis reaction device and system, which is particularly suitable for the reaction process of converting carbon dioxide (CO2) and hydrogen (H2) into methanol. It can improve the reaction yield and selectivity and improve energy utilization efficiency by optimizing the CO2 reduction reaction process. According to the embodiments, the design scheme of this utility model, by adding the feed control unit, controls the proportion of reactants being fed, ensuring that reactants in subsequent processing stages can be mixed in a specific ratio to optimize chemical reaction conditions; by adding the ionization treatment unit and applying the ionization reactor, effective ionization treatment of reactants is achieved, providing an ideal reactant form for subsequent chemical reactions and ensuring the efficient operation of the entire ionization-coupled artificial photosynthesis reaction device; by adding the ionization feedback unit, effective separation and recycling of reactants after ionization treatment are achieved, improving the system's resource utilization rate, reducing the waste of unionized reactants, and ensuring the efficient operation of the entire ionization-coupled artificial photosynthesis reaction device; by adding the catalytic regeneration reactor unit, effective regeneration and recycling of the catalyst are achieved, ensuring the efficient operation of the entire ionization-coupled artificial photosynthesis reaction device, improving catalyst utilization, reducing resource waste, and ensuring the stability and efficiency of the entire system.
[0047] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention.
[0048] Figure 1 A schematic diagram of an ionization-coupled artificial photosynthesis reaction apparatus is shown according to an example embodiment.
[0049] See Figure 1The figure shows an ionization-coupled artificial photosynthesis reaction device, which includes: a feed control unit 01, an ionization treatment unit 02, an ionization feedback unit 03, a catalytic regeneration reactor unit 04, and a product separation unit 05. According to some embodiments, the feed control unit 01 is used to deliver a predetermined proportion of reactants to the ionization treatment unit 02, ensuring that the reactants entering subsequent processing stages are mixed in a specific ratio to optimize chemical reaction conditions.
[0050] According to some embodiments, the ionization treatment unit 02 is used to ionize the reactant (H2) and send the ionized reactant to the ionization feedback unit 03. By using the ionization treatment unit 02 to ionize the reactant from the feed control unit 01 and sending the ionized substance to the ionization feedback unit 03, the state of the reactant is changed through ionization treatment, preparing it for subsequent chemical reactions.
[0051] According to some embodiments, the ionization feedback unit 03 separates the ionized and unionized reactants from the ionized reactants, and sends the ionized reactants into the catalytic regeneration reactor unit 04, while the unionized reactants are returned to the feed control unit 01. The ionization feedback unit 03 receives the ionized reactants from the ionization treatment unit 02 and separates the ionized and unionized reactants. The ionized reactants are sent to the catalytic regeneration reactor unit 04 for further processing, while the unionized reactants are returned to the feed control unit 01 for reprocessing.
[0052] According to some embodiments, the catalytic regeneration reactor unit 04 is used for preheating and activation regeneration of the catalyst, as well as for the chemical reaction of the ionized reactants under the action of the catalyst, to obtain a mixture of the target product and the ionized reactants, and then the mixture is sent to the product separation unit 05. In the catalytic regeneration reactor unit 04, the ionized reactants undergo a chemical reaction under the action of the catalyst to generate the target product and a mixture containing the ionized reactants, thus achieving chemical transformation. Generally, the types of catalysts that can be used in the catalytic regeneration reactor unit 04 include copper-based catalysts, noble metal catalysts, or composite oxide catalysts. The catalyst is activated, regenerated, and reused in the chemical reaction process within the catalytic regeneration reactor unit 04. This design achieves efficient recycling of the catalyst, reduces production costs, and also reduces waste generation, which is beneficial to environmental protection.
[0053] According to some embodiments, the catalytic regeneration reactor unit can also employ a photocatalyst in conjunction with a light source to achieve artificial photosynthesis. Specifically, a light source is provided in the catalytic regeneration reactor to illuminate the chemical reaction. A light-transmitting window is provided on the reactor, allowing the light source to shine through the window into the reactor interior, thereby enhancing the efficiency of the chemical reaction under the action of the photocatalyst.
[0054] According to some embodiments, the product separation unit 05 separates the target product and the ionized reactants from the mixture, and returns the ionized reactants to the catalytic regeneration reactor unit 04 to obtain the target product. The product separation unit 05 is used to separate the target product and the ionized reactants from the mixture output from the catalytic regeneration reactor unit 04, extract the final product, and return any unconsumed ionized reactants to the catalytic regeneration reactor unit 04 for reuse, thereby improving resource utilization.
[0055] According to some embodiments, the design scheme of this utility model simulates the photosynthetic process in nature through artificial photosynthesis. Under artificial conditions, such as through catalysts, light, high temperature and high pressure, carbon dioxide (CO2) reacts with hydrogen (H2) to produce hydrocarbons. This artificial photosynthetic reaction method can effectively promote the green conversion of carbon dioxide (CO2), efficiently collect energy substances, avoid energy loss in natural systems, and simultaneously alleviate environmental pollution and address the problem of fossil fuel shortages.
[0056] Figure 2 A schematic diagram of an ionization-coupled artificial photosynthesis reaction apparatus is shown according to another exemplary embodiment.
[0057] See Figure 2 The figure illustrates an ionization-coupled artificial photosynthesis reaction apparatus according to another exemplary embodiment. The feed control unit 01 includes at least two reactant delivery channels 0101 and a flow controller 0103. One of the reactant delivery channels 0101 receives the unionized reactants from the ionization feedback unit, which are then reintroduced into the system for further processing. Allowing the unionized reactants to return to the feed control unit 01 for further processing helps improve the overall system's resource utilization, reduces waste, and ensures maximum resource utilization. The remaining reactant delivery channels 0101 supply reactants to the ionization treatment unit 02, ensuring that appropriate reactants are input according to process requirements. The presence of multiple reactant delivery channels 0101 allows the system to adapt to different operating conditions and raw material types, increasing the flexibility and applicability of the apparatus.
[0058] According to some embodiments, the flow controller 0103 is disposed in the reactant delivery channel 0101 and is used to control the input ratio of each reactant. The flow controller 0103 is used to precisely control the input ratio of each reactant, ensuring that the various reactants entering the system can be mixed in a predetermined ratio, thereby optimizing the subsequent chemical reaction process.
[0059] According to some embodiments, the feed control unit 01 not only effectively manages the input of reactants but also reprocesses unionized reactants through an internal circulation mechanism, thereby improving the efficiency and economy of the entire ionization-co-processing artificial photosynthesis reactor. Furthermore, precise flow control maintains subsequent chemical reactions under optimal conditions, contributing to improved final product quality and yield. Taking the industrial application of methanol production from carbon dioxide (CO2) and hydrogen (H2) as an example, the feed control unit 01 can introduce CO2 and H2 into the ionization treatment unit 02 through two reactant delivery channels 0101, respectively. Each reactant delivery channel 0101 is equipped with a flow regulating valve. By adjusting the flow regulating valve, the feed rate of each reactant can be precisely controlled to meet the requirements under different reaction conditions.
[0060] See Figure 2 The ionization treatment unit 02 includes an ionization reactor 0201 for ionizing the input reactants. The ionization reactor 0201, as the core component of the ionization treatment unit 02, is specifically designed to ionize the input reactants, converting reactant molecules or atoms into charged particles (ions) through a specific method. By utilizing the ionization reactor 0201, the ionization treatment unit 02 achieves effective ionization of the reactants, providing an ideal reactant form for subsequent chemical reactions. Ionization treatment can significantly alter the chemical properties of the reactants, making them more readily involved in subsequent chemical reactions, thus ensuring the efficient operation of the entire ionization-coupled artificial photosynthesis reaction device.
[0061] According to some embodiments, the ionization reactor 0201 employs a radio frequency plasma generator or a dielectric barrier discharge plasma generator. The radio frequency plasma generator uses high-frequency electromagnetic waves to excite gas and generate plasma, thereby achieving ionization; the dielectric barrier discharge plasma generator generates plasma by applying a high voltage between electrodes and inserting an insulating medium therebetween, achieving the same ionization effect. After ionization, the reactants are converted into a mixture containing ionized and unionized reactants, which is then fed into the ionization feedback unit 03 for further processing. Specifically, the ionization processing unit receives various reactants input from the feed control unit 01 according to a set ratio. Inside the ionization reactor 0201, the reactants are ionized by radio frequency plasma or dielectric barrier discharge, forming highly reactive ions and free radicals. These highly reactive particles are more likely to participate in subsequent chemical reactions, thereby lowering the activation energy of the reaction and promoting its progress. Afterwards, the ionized reactants (including ionized and unionized reactants) are transported to the ionization feedback unit 03 for further separation and processing.
[0062] See Figure 2 The ionization feedback unit 03 includes an ionization separator 0301 for separating the ionized reactants and the unionized reactants. The ionization separator 0301 employs an electric field separation device, utilizing the different responses of an electric field to charged particles (ionized reactants) and unionized particles (unionized reactants) to achieve separation. The ionization separator 0301 uses the electric field to separate the ionized and unionized reactants in the reactant mixture after treatment by the ionization treatment unit 02. The ionized reactants, carrying a charge, move along a specific path under the influence of the electric field and are guided to the catalytic reaction unit 04.
[0063] According to some embodiments, the ionization feedback unit 03 further includes a first feedback channel 0303, which is connected to the reactant transport channel 0101 to return the unionized reactants to the ionization treatment unit 02. The ionization separator 0301 uses an electric field to separate the ionized and unionized reactants in the reactant mixture processed by the ionization treatment unit 02. The unionized reactants are unaffected by the electric field and continue along their original path into the first feedback channel 0303. The first feedback channel 0303 is connected to the reactant transport channel 0101 to return the unionized reactants to the ionization treatment unit 02 for reprocessing. This design improves system resource utilization, reduces waste, and enhances overall efficiency.
[0064] According to some embodiments, the ionization feedback unit 03, through the ionization separator 0301 and the first feedback channel 0303, achieves effective separation and recycling of reactants after ionization treatment. This design not only improves the system's resource utilization rate and reduces the waste of unionized reactants, but also ensures the efficient operation of the entire ionization-co-processed artificial photosynthesis reaction device. Specifically, the ionization feedback unit 03 is connected after the ionization reactor 0201 and can separate ionized and unionized reactants. This function can be achieved using an electric field separation device. The electric field separation device utilizes the principle that ions and neutral molecules experience different forces in an electric field to separate ionized reactant ions. Unionized reactants are returned to the ionization reactor 0201 through the first feedback channel 0303 for further ionization treatment, improving reactant utilization. Ionized reactants then enter the catalyst reactor. This closed-loop design makes the system more efficient and economical, and better adaptable to different reaction conditions and requirements.
[0065] According to some embodiments, the catalytic regeneration reactor unit 04 includes: a catalyst regenerator 0401 and a fluidized bed reactor 0403. The catalyst regenerator 0401 includes an inlet 04011 and a riser 04013. The catalyst is added to the catalyst regenerator 0401 through the inlet 04011. After preheating and regeneration of the catalyst in the catalyst regenerator 0401, the catalyst is fed into the fluidized bed reactor 0403 through the riser 04013. Reactor 0403 receives catalyst from catalyst regenerator 0401 and ionized reactants from ionization feedback unit 03. In the fluidized bed reactor 0403, each reactant undergoes a fluidized reaction under the action of the catalyst to obtain a mixture of the target product and the ionized reactants. The fluidized bed reactor 0403 includes a first reflux pipe 04031, which is disposed at the bottom of the fluidized bed reactor 0403 to recover the deactivated catalyst after the reaction and return it to the catalyst regenerator 0401.
[0066] According to some embodiments, the catalyst regenerator 0401 is used to regenerate deactivated catalysts and restore their activity. Fresh catalyst is added through the feed inlet 04011, preheated in the catalyst regenerator 0401, and then conveyed to the fluidized bed reactor 0403 through the riser 04013, ready to participate in subsequent chemical reactions.
[0067] According to some embodiments, the fluidized bed reactor 0403 receives catalyst from the catalyst regenerator 0401 and ionized reactants from the ionization feedback unit 03, and carries out a chemical reaction (typically a fluidized reaction) under the action of the catalyst to generate the target product. Under the action of the catalyst, the ionized reactants undergo a chemical reaction to generate the desired product and possible byproducts. After the reaction, the target product and the unreacted ionized reactants form a mixture, which is sent to the product separation unit 05 for further processing. During the reaction, some catalyst may be deactivated; this deactivated catalyst is recovered through the first reflux pipe 04031 and sent back to the catalyst regenerator 0401 for regeneration.
[0068] According to some embodiments, the catalyst enters the catalyst regenerator 0401 through the feed inlet 04011 for preheating. Then, the catalyst enters the fluidized bed reactor 0403 through the riser 04013 and mixes evenly with the ionized reactants. The ionized reactants enter the reactor 0403 through the bottom. Deactivated catalyst accumulates at the bottom of the fluidized bed reactor 0403 due to gravity and enters the catalyst regenerator 0401 through the first reflux pipe for activation. The activated catalyst and fresh catalyst then enter the fluidized bed reactor 0403 together through the riser 04013 for reaction.
[0069] According to some embodiments, the catalyst regenerator 0401 can be configured with a gravity detection system to determine the specific time and dosage of adding fresh catalyst, so as to ensure that the overall chemical reaction conditions of the system are always in the optimal state.
[0070] According to some embodiments, the catalytic regeneration reactor unit 04, through the catalyst regenerator 0401 and the fluidized bed reactor 0403, achieves effective regeneration and recycling of the catalyst, ensuring the efficient operation of the entire ionization-coupled artificial photosynthesis reactor. Specifically, the catalyst regenerator 0401 is responsible for regenerating the deactivated catalyst and transporting the regenerated catalyst to the fluidized bed reactor 0403 through the riser 04013. The fluidized bed reactor 0403 receives the ionized reactants and the regenerated catalyst, and a chemical reaction takes place under the action of the catalyst to generate the target product. The deactivated catalyst is then recovered through the first reflux pipe 04031 for regeneration. This design not only improves the utilization rate of the catalyst and reduces resource waste, but also ensures the stability and efficiency of the entire system.
[0071] According to some embodiments, the catalyst introduced into the catalytic regeneration reactor unit 04 is used to promote the reaction of ionized reactants to generate the target product. For example, copper-based catalysts, noble metal catalysts, or composite oxide catalysts can further improve the selectivity and efficiency of the reaction, enabling the ionized reactants to be efficiently converted into the target product under relatively mild conditions. For example, in the methanol production reaction, the catalyst can promote the reaction of ions and free radicals to generate methanol.
[0072] According to some embodiments, the product separation unit 05 includes a separator 0501 and a second reflux pipe 0503. The separator 0501 is used to separate the target product and the ionized reactants in the mixture and to externally transport the target product. The second reflux pipe 0503 connects the separator 0501 and the fluidized bed reactor 0403, returning the ionized reactants to the fluidized bed reactor 0403. The separator 0501 is connected after the fluidized bed reactor 0403 to separate the target product and return the incompletely reacted ionized reactants to the fluidized bed reactor 0403. The separator 0501 can be flexibly selected according to the physical and chemical properties of the reaction products and the target product. Specifically, it can employ a condenser, membrane separation, or adsorption device, or a combination of these methods, to achieve target product separation. The condenser utilizes the difference in boiling points of different substances to separate the target product from the reaction mixture. The membrane separation component separates different substances based on the difference in permeation rates within the membrane. These separation methods enable efficient separation of the target product from the unreacted product, allowing the unreacted product to be recycled and further improving the economic efficiency of the reaction.
[0073] According to some embodiments, the second reflux pipe 0503 connects the separator 0501 and the fluidized bed reactor 0403, returning the incompletely reacted ionized reactants to the fluidized bed reactor 0403 so that they can participate in the chemical reaction again, thereby improving the resource utilization rate of the entire system and ensuring that the incompletely reacted substances are not wasted but returned to the reaction system, thus improving overall efficiency. Specifically, the mixture from the fluidized bed reactor 0403 (containing the target product and the incompletely reacted ionized reactants) enters the separator 0501. In separator 0501, the mixture is separated into two parts: the target product and the ionized reactants. The separated target product is collected and transported for subsequent processing or direct application, while the incompletely reacted ionized reactants are separated and sent back to the fluidized bed reactor 0403 through the second reflux pipe 0503. Under the action of the catalyst, they continue to participate in the chemical reaction, forming a closed-loop system. This ensures the high-quality output of the target product while reducing resource waste by recycling the incompletely reacted substances, thus enhancing the system's economy and environmental friendliness.
[0074] Figure 3 A schematic diagram of the feed control unit and ionization treatment unit of an ionization-coupled artificial photosynthesis reaction apparatus according to another exemplary embodiment is shown.
[0075] The figure shows the feed control unit 01 and ionization treatment unit 02 of an ionization-co-processed artificial photosynthesis reactor. See also Figure 2 as well as Figure 3 Taking the process of preparing methanol from carbon dioxide (CO2) and hydrogen (H2) in industrial applications as an example, the feed control unit 01 can send CO2 and H2 into the ionization treatment unit 02 through two reactant conveying channels 0101, and each reactant conveying channel 0101 is equipped with a flow regulating valve. By adjusting the flow regulating valve, the feed amount of each reactant can be precisely controlled to meet the needs under different reaction conditions.
[0076] Subsequently, the ionization reactor 0201 ionizes the input reactant (H2). After ionization, the reactant is converted into a mixture containing ionized and unionized reactants and transported to the ionization feedback unit 03. In the ionization feedback unit 03, the ionized and unionized reactants in the reactant mixture processed by the ionization treatment unit 02 are separated. The ionized reactants, carrying a charge, move along a specific path under the influence of an electric field and are guided to the catalytic reaction unit 04. The unionized reactants, unaffected by the electric field, continue along their original path and enter the first feedback channel 0303. The first feedback channel 0303 is connected to the reactant transport channel 0101, returning the unionized reactants to the ionization treatment unit 02 for reprocessing.
[0077] According to some embodiments, the first feedback channel 0303 is connected to the reactant delivery channel 0101, and a jet pump can be used to replenish new H2 with high-pressure gas to drive the unionized H2 to be drawn in and sent back to the inlet.
[0078] According to some embodiments, based on specific reaction progress control needs and requirements, component detectors 06 can be installed at the outlet of ionization reactor 0201 and separator 0501, respectively. The test data from these component detectors 06 is used to adjust the corresponding flow regulators on the CO2 and / or H2 channels to ensure the raw material ratio, allowing subsequent chemical reactions to proceed under optimal conditions and improving system reaction efficiency. For industrial methanol production, the reactant flow rate is controlled at a volume ratio of 1:2 to 4.
