Description

Technical Field

[0001] The present invention relates to the technical field of catalytic chemistry, and particularly to an ionization-coupled artificial photosynthesis reaction device and reaction system. Background Art

[0002] All along, the reduction reaction of carbon dioxide (CO2) has been a research hotspot in the global green chemistry field. Most of the existing methods require a large amount of energy input, such as through high-temperature and high-pressure conditions or electrolysis conditions, which not only increases the operation cost but may also indirectly lead to more carbon emissions.

[0003] Converting CO2 into useful chemicals or fuels is a non-spontaneous process that usually requires additional energy to overcome this barrier. During the reduction process, in addition to the target products, multiple by-products often occur. For example, during the electrocatalytic reduction of CO2, various compounds such as formic acid, carbon monoxide, and ethylene may be generated simultaneously, and the ratio of these by-products is difficult to precisely control. To achieve efficient conversion, precious metals are sometimes used as catalysts, which not only increases the cost but may also cause resource shortage problems. Moreover, after long-term operation, the catalyst surface is prone to carbon deposition or being covered by other pollutants, resulting in a decrease in its activity, thereby reducing the selectivity and yield of the products.

[0004] Whether it is developing efficient catalysts or maintaining the conditions required for the reaction (such as temperature, pressure), it will bring relatively high costs. In addition, equipment maintenance and energy consumption are also important economic burdens. Many CO2 reduction technologies involve multi-step reaction paths and require complex equipment and delicate operating conditions. This not only increases the technical difficulty but also raises the risk of system failures. Moreover, some reduction technologies may produce harmful by-products or emit other greenhouse gases, such as nitrogen oxides (NOx), volatile organic compounds (VOCs), etc., posing a new threat to the environment.

[0005] Due to the above reasons, the chemicals or fuels produced by CO2 reduction are often not price-competitive 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. Summary of the Invention

[0044] In recent years, the reduction reaction of CO2 has been a research hotspot in the global green chemistry field. Most of the existing methods require a large amount of energy input, such as through high-temperature catalytic reactions, which usually require high-temperature and high-pressure conditions, and the reaction efficiency and selectivity are relatively low.

[0045] Plasma technology is considered a low-temperature and efficient gas ionization method that can promote the activation and decomposition of H2 molecules. However, simple plasma reactions often have problems such as low energy utilization efficiency and poor product selectivity. Catalysts can improve the selectivity and efficiency of reactions, but in some cases, the activation degree of reactants is limited. Therefore, combining plasma ionization with catalysts is expected to overcome their respective disadvantages and achieve an efficient and energy-saving chemical reaction process.

[0046] The present invention relates to an ionization combined 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 optimize the process of CO2 reduction reaction, improve the reaction yield and selectivity, and improve the energy utilization efficiency. According to the embodiment, the design scheme of the present invention controls the feeding ratio of the reactants by adding the feeding control unit, ensuring that the reactants in the subsequent treatment stage can be mixed in a specific ratio to optimize the chemical reaction conditions; by adding the ionization treatment unit and applying the ionization reactor, effective ionization treatment of the reactants is achieved, providing an ideal reactant form for subsequent chemical reactions and ensuring the efficient operation of the entire ionization combined artificial photosynthesis reaction device; by adding the ionization feedback unit, effective separation and recycling of the reactants after ionization treatment are achieved, improving the resource utilization rate of the system, reducing the waste of un-ionized reactants, and also ensuring the efficient operation of the entire ionization combined 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 combined artificial photosynthesis reaction device, improving the utilization rate of the catalyst, reducing resource waste, and also ensuring the stability and efficiency of the entire system.

[0047] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0048] Figure 1 Fig. shows a schematic diagram of an ionization combined artificial photosynthesis reaction device according to an exemplary embodiment.

[0049] See Figure 1 , in the figure, an ionization combined artificial photosynthesis reaction device is shown, and the device includes: a feeding 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 feeding control unit 01 is used to transport reactants in a set ratio to the ionization treatment unit 02, ensuring that the reactants entering the subsequent treatment stage can be mixed in a specific ratio to optimize the chemical reaction conditions.

[0050] According to some embodiments, the ionization treatment unit 02 is used to perform ionization treatment on the reactant (H2) and send the ionized reactant into the ionization feedback unit 03. The ionization treatment unit 02 is applied to perform ionization treatment on the reactant from the feed control unit 01 and send the ionized substance into the ionization feedback unit 03, changing the state of the reactant through ionization treatment to prepare for subsequent chemical reactions.

[0051] According to some embodiments, the ionization feedback unit 03 separates the ionized reactant and the non-ionized reactant in the ionized reactant after the ionization treatment, sends the ionized reactant into the catalytic regeneration reactor unit 04, and sends the non-ionized reactant back into the feed control unit 01. The ionization feedback unit 03 is used to receive the ionized reactant from the ionization treatment unit 02 and separate the ionized reactant and the non-ionized reactant. Among them, the ionized reactant is sent to the catalytic regeneration reactor unit 04 for further treatment, while the non-ionized reactant returns to the feed control unit 01 for re-treatment.

[0052] According to some embodiments, the catalytic regeneration reactor unit 04 is used for preheating and activating the regeneration of the catalyst and the occurrence of chemical reactions of the ionized reactant under the action of the catalyst, obtaining a mixture of the target product and the ionized reactant, and sending the mixture into the product separation unit 05. In the catalytic regeneration reactor unit 04, under the action of the catalyst, the ionized reactant undergoes a chemical reaction to generate the target product and a mixture containing the ionized reactant, realizing chemical conversion. Generally, the types of catalysts that can be applied in the catalytic regeneration reactor unit 04 include copper-based catalysts, noble metal catalysts, or composite oxide catalysts, etc. The catalyst is activated and regenerated inside the catalytic regeneration reactor unit 04 and reused in the chemical reaction process. This design realizes the efficient recycling of the catalyst, reduces production costs, and also reduces the generation of waste, which is beneficial to environmental protection.

[0053] According to some embodiments, the catalytic regeneration reactor unit can also adopt the method of applying a photocatalyst in combination with a light source to achieve artificial photosynthesis. Specifically, a light source is set in the catalytic regeneration reactor to provide light for the chemical reaction. A light-transmitting window is reserved on the reactor so that the light source passes through the light-transmitting window and irradiates the inside of the reactor, and under the action of the photocatalyst, the chemical reaction efficiency is improved.

[0054] According to some embodiments, the product separation unit 05 separates the target product and the ionized reactants in the mixture, and sends the ionized reactants back 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 in the mixture output by the catalytic regeneration reactor unit 04, extract the final product, and return the incompletely consumed ionized reactants to the catalytic regeneration reactor unit 04 for reuse, improving the resource utilization rate.

[0055] According to some embodiments, the design of the present invention simulates the photosynthesis process in nature through artificial photosynthesis. Under artificial conditions, for example, by means of catalysts, light, high temperature and high pressure, carbon dioxide (CO2) reacts with hydrogen (H2) to generate hydrocarbons. Through such an artificial photosynthesis reaction method, the green conversion of carbon dioxide (CO2) can be effectively promoted, energy substances can be efficiently collected, energy loss in the natural system can be avoided, and the problems of environmental pollution mitigation and fossil energy shortage can be taken into account.

[0056] Figure 2 Fig. shows a schematic diagram of an ionization combined with artificial photosynthesis reaction device according to another exemplary embodiment.

[0057] See Figure 2 , the figure shows an ionization combined with artificial photosynthesis reaction device 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 is used to receive the un-ionized reactants from the ionization feedback unit, and this part of the un-ionized reactants will be reintroduced into the system for further processing. Allowing the un-ionized reactants to return to the feed control unit 01 and then be processed helps to improve the resource utilization rate of the entire system, reduce waste, and ensure the maximum utilization of resources. The remaining reactant delivery channels 0101 are used to deliver reactants to the ionization treatment unit 02 to ensure that the appropriate reaction substances are input according to the process requirements. The presence of multiple reactant delivery channels 0101 enables the system to adapt to different operating conditions and raw material types, increasing the flexibility and application range of the device.

[0058] According to some embodiments, the flow controller 0103 is disposed in the reactant delivery channel 0101 for controlling the input ratio of each reactant. The flow controller 0103 is used to precisely control the input ratio of each reactant, ensuring that 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 can not only effectively manage the input of reactants, but also realize the reprocessing of un-ionized reactants through an internal circulation mechanism, thereby improving the efficiency and economy of the entire ionization-coupled artificial photosynthesis reaction device. In addition, precise flow control can maintain the subsequent chemical reactions under optimal conditions, contributing to the improvement of the quality and yield of the final products. Taking the process of preparing methanol from industrial application carbon dioxide (CO2) and hydrogen (H2) as an example, the feed control unit 01 can respectively introduce CO2 and H2 into the ionization treatment unit 02 through 2 reactant delivery channels 0101, and flow regulating valves are respectively provided on each reactant delivery channel 0101. By adjusting the flow regulating valves, the feed amount 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. Among them, the ionization reactor 0201, as the core component of the ionization treatment unit 02, is specifically used for ionizing the input reactants, that is, converting reactant molecules or atoms into charged particles (ions) by a certain method. The ionization treatment unit 02 realizes the effective ionization treatment of reactants by applying the ionization reactor 0201, provides an ideal reactant form for the subsequent chemical reactions, can significantly change the chemical properties of reactants through ionization treatment, making them more likely to participate in the subsequent chemical reactions, and 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. Among them, the radio frequency plasma generator uses high-frequency electromagnetic waves to excite gas to 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 to achieve an ionization effect. After ionization treatment, the reactants are converted into a mixture containing ionized reactants and un-ionized reactants, and these substances are sent to the ionization feedback unit 03 for further treatment. Specifically, the ionization treatment unit receives various reactants input from the feed control unit 01 in a set proportion. Inside the ionization reactor 0201, the reactants are ionized by means of radio frequency plasma or dielectric barrier discharge to form highly active particles such as ions and free radicals. These highly active particles are more likely to participate in the subsequent chemical reactions, thereby reducing the activation energy of the reaction and promoting the reaction. After that, the reactants after ionization treatment (including ionized reactants and un-ionized reactants) are transported to the ionization feedback unit 03 for further separation and treatment.

[0062] See Figure 2, the ionization feedback unit 03 includes an ionization separator 0301 for separating the ionized reactants and the non-ionized reactants. The ionization separator 0301 employs an electric field separation device to achieve separation by utilizing the different responses of charged particles (ionized reactants) and uncharged particles (non-ionized reactants) to the electric field. The ionization separator 0301 separates the ionized reactants and the non-ionized reactants in the reactant mixture that has been processed by the ionization treatment unit 02 by means of the action of the electric field. Among them, the ionized reactants, due to carrying charges, will move along a specific path under the action of the electric field and be directed to the catalytic reaction unit 04.

[0063] According to some embodiments, the ionization feedback unit 03 further includes: a first feedback channel 0303 that is connected to the reactant delivery channel 0101 to send the non-ionized reactants back to the ionization treatment unit 02. The ionization separator 0301 separates the ionized reactants and the non-ionized reactants in the reactant mixture that has been processed by the ionization treatment unit 02 by means of the action of the electric field. Among them, the non-ionized reactants are not affected by the electric field and continue to move along the original path and enter the first feedback channel 0303. The first feedback channel 0303 is connected to the reactant delivery channel 0101 to send the non-ionized reactants back to the ionization treatment unit 02 for reprocessing. Such a design improves the resource utilization rate of the system, reduces waste, and enhances the overall efficiency.

[0064] According to some embodiments, the ionization feedback unit 03, through the ionization separator 0301 and the first feedback channel 0303, realizes the effective separation and recycling of the reactants after ionization treatment. This design not only improves the resource utilization rate of the system, reduces the waste of non-ionized reactants, but also ensures the efficient operation of the entire ionization combined artificial photosynthesis reaction device. Specifically, the ionization feedback unit 03 is connected after the ionization reactor 0201 and can separate the ionized and non-ionized reactants. An electric field separation device can be used to achieve this function. The electric field separation device separates the ionized reactant ions by utilizing the principle that ions and neutral molecules are affected differently by the electric field. The non-ionized reactants return to the ionization reactor 0201 through the first feedback channel 0303 and continue to be ionized, improving the utilization rate of the reactants. The ionized reactants enter the catalyst reactor. This closed-loop design makes the system more efficient, economical, and better able to adapt 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. Among them, the catalyst regenerator 0401 includes a feed inlet 04011 and a riser 04013. The catalyst is added into the catalyst regenerator 0401 through the feed inlet 04011. After preheating and regenerating the catalyst in the catalyst regenerator 0401, the catalyst is sent into the fluidized bed reactor 0403 through the riser 04013; the fluidized bed reactor 0403 receives the catalyst from the catalyst regenerator 0401 and the ionized reactants from the ionization feedback unit 03. In the fluidized bed reactor 0403, each of the reactants 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 return pipe 04031, which is arranged 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 the deactivated catalyst to restore its activity. Fresh catalyst is added through the feed inlet 04011. In the catalyst regenerator 0401, the fresh catalyst is preheated, and then the preheated catalyst is transported to the fluidized bed reactor 0403 through the riser 04013 to prepare for subsequent chemical reactions.

[0067] According to some embodiments, the fluidized bed reactor 0403 receives the catalyst from the catalyst regenerator 0401 and the ionized reactants from the ionization feedback unit 03, and undergoes a chemical reaction (usually 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 by-products. 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 process, some of the catalyst may be deactivated, and these deactivated catalysts are recovered through the first return pipe 04031 and sent back to the catalyst regenerator 0401 for regeneration treatment.

[0068] According to some embodiments, the catalyst enters the catalyst regenerator 0401 from the feed inlet 04011 to preheat the catalyst in advance. Then, the catalyst enters the fluidized bed reactor 0403 through the riser 04013 and is mixed evenly with the ionized reactants. The ionized reactants enter the reactor through the bottom of the fluidized bed reactor 0403. The deactivated catalyst will accumulate at the bottom of the fluidized bed reactor 0403 due to gravity, and then enter the catalyst regenerator 0401 through the first return pipe for activation. The activated catalyst and the fresh catalyst enter the fluidized bed reactor 0403 through the riser 04013 for reaction together.

[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 the fresh catalyst input, so as to ensure that the overall chemical reaction conditions of the system are continuously in the best state.

[0070] According to some embodiments, the catalytic regeneration reactor unit 04 realizes the effective regeneration and recycling of the catalyst through the catalyst regenerator 0401 and the fluidized bed reactor 0403, ensuring the efficient operation of the entire ionized combined artificial photosynthesis reaction device. 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 carries out chemical reactions under the action of the catalyst to generate the target product, and recovers the deactivated catalyst through the first return pipe 04031 for regeneration. Such a design not only improves the utilization rate of the catalyst, 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 the ionized reactants to generate the target product. For example, copper-based catalysts, noble metal catalysts, or composite oxide catalysts, etc. These 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 reaction of producing methanol, the catalyst can promote the reaction of ions and free radicals of and 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 convey the target product externally. The second reflux pipe 0503 connects the separator 0501 and the fluidized bed reactor 0403 to return the ionized reactants to the fluidized bed reactor 0403. Among them, the separator 0501 is connected after the fluidized bed reactor 0403, used 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, a condenser, membrane separation, adsorption device, or a combination of multiple methods can be used to achieve the separation of the target product. Among them, the condenser uses the difference in boiling points of different substances to separate the target product from the reaction mixture. The membrane separation component separates according to the difference in the permeation rates of different substances in the membrane. Through these separation means, the efficient separation of the target product and the unreacted products is achieved, and the unreacted products are recycled, further improving the economy of the reaction.

[0073] According to some embodiments, the second reflux pipe 0503 connects the separator 0501 and the fluidized bed reactor 0403 to return the incompletely reacted ionized reactants to the fluidized bed reactor 0403, enabling them to participate in the chemical reaction again, thereby improving the resource utilization rate of the entire system, ensuring that the incompletely reacted substances are not wasted but return to the reaction system, and improving the overall efficiency. Specifically, the mixture (containing the target product and the incompletely reacted ionized reactants) from the fluidized bed reactor 0403 enters the separator 0501. In the separator 0501, the mixture is separated into two parts: the target product and the ionized reactants. Among them, the separated target product is collected and conveyed externally for subsequent processing or direct application, while the incompletely reacted ionized reactants are separated and returned to the fluidized bed reactor 0403 through the second reflux pipe 0503 to continue participating in the chemical reaction under the action of the catalyst, forming a closed-loop system, ensuring the high-quality output of the target product while reducing resource waste by recycling the incompletely reacted substances, enhancing the economy and environmental friendliness of the system.

[0074] Figure 3 Shows a schematic diagram of the feed control unit and the ionization treatment unit of an ionization combined artificial photosynthesis reaction device according to another exemplary embodiment.

[0075] The figure shows a part of the feed control unit 01 and the ionization treatment unit 02 of an ionization combined artificial photosynthesis reaction device. See Figure 2 and Figure 3, taking the process of preparing methanol from industrial application of carbon dioxide (CO2) and hydrogen (H2) as an example, the feed control unit 01 can respectively feed CO2 and H2 into the ionization treatment unit 02 through 2 reactant delivery channels 0101, and flow regulating valves are respectively provided on each reactant delivery channel 0101. By adjusting the flow regulating valves, the feed amount of each reactant can be accurately controlled to meet the requirements under different reaction conditions.

[0076] After that, the ionization reactor 0201 performs ionization treatment on the input reactant (H2). After the ionization treatment, the reactant is converted into a mixture containing ionized reactants and non-ionized reactants and is transported to the ionization feedback unit 03. In the ionization feedback unit 03, the ionized reactants and non-ionized reactants in the reactant mixture processed by the ionization treatment unit 02 are separated. Among them, the ionized reactants, due to carrying charges, will move along a specific path under the action of an electric field and are directed to the catalytic reaction unit 04.
