Description

Technical Field

[0001] The present application relates to a novel thermal radiation catalytic reaction device and method in which high temperature and radiation are synergistically controllable, and belongs to the field of chemical catalysis. Background Art

[0002] Thermal radiation is the phenomenon of an object emitting electromagnetic waves due to its own temperature, with distinct wavelength characteristics. For example, the sun can be considered a sphere with a surface temperature of approximately 5770K. The energy radiated to the Earth's surface can be divided into the ultraviolet band (<0.38μm), the visible light band (0.38-0.76μm), and the infrared band (>0.76μm), accounting for approximately 7%, 50%, and 43% of the total solar radiation energy, respectively. Any object with a temperature above absolute zero will continuously emit radiant energy.

[0003] Thermal catalysis is the most common catalytic technology and plays a vital role in fields such as petroleum processing, chemical industry, and pharmaceutical industry. In a thermal catalytic system, the energy required for the reactant molecules to transform from a normal state to an active state that is prone to chemical reactions is defined as activation energy. Breaking the activation energy usually requires relatively harsh reaction conditions such as high temperature and high pressure. Traditional thermal catalysis methods usually regard thermal energy as the primary driving force of the reaction, but often ignore the thermal radiation energy in high-temperature environments, which limits the reaction rate and overall energy efficiency.

[0004] According to Planck's law, a blackbody (an ideal object with both absorptivity and emissivity of 1) has a peak wavelength in the infrared region when its temperature is below 3600K. This means that the radiation energy of most thermal catalytic reactions is concentrated in the infrared band, where a large number of gas molecules also have characteristic infrared absorption peaks. Recent research has shown that when the peak radiation energy matches the characteristic infrared absorption peak of the gas reactant molecules, it can significantly enhance the gas molecules' absorption of radiation energy and excite their specific vibrational modes, thereby intensifying inelastic collisions between molecules and reducing the activation energy required for the reaction, thereby lowering reaction conditions and increasing reaction rates. This type of reaction is known as thermal radiation catalysis.

[0005] Currently, research on thermal radiation catalysis is just beginning, and there is a lack of effective reaction device design solutions and energy control strategies, making it difficult to achieve gentle and efficient thermal radiation catalytic reactions. In view of this, the present invention proposes for the first time a new thermal radiation catalytic reaction device and method that can synergistically control high temperature and radiation. By synergistically controlling the reaction temperature and radiation energy, the activation energy required for the reaction is reduced, thereby achieving continuous and efficient catalytic reactions and chemical production under relatively mild reaction conditions. This reaction device is suitable for most gas-phase reactions and gas-solid coupling reactions in multiple industrial fields such as energy, chemical industry, manufacturing, and environmental protection, and can serve as a better alternative to traditional thermal catalytic reaction devices. Summary of the Invention

[0006] This application proposes for the first time a new type of thermal radiation catalytic reaction device and method in which high temperature and radiation are synergistically controlled. The reaction activation energy is reduced by synergistic regulation of high temperature and thermal radiation, thereby overcoming the shortcomings of traditional thermal catalytic methods such as low reaction efficiency and harsh reaction conditions.

[0053] Example 2: Combining Figure 2 The present application also discloses a novel thermal radiation catalytic reaction method in which high temperature and radiation are synergistically controlled, which is implemented using the novel thermal radiation catalytic reaction device in which high temperature and radiation are synergistically controlled as described in Example 1, and comprises the following steps:

[0054] Step 1: Determine the basic parameters; according to the given reaction equation, determine the activation energy E required for the reaction under common thermal catalytic systems a , reaction temperature T r , and the infrared characteristic absorption peak λ of the main reactant gas molecules g Here, a gas molecule may have multiple infrared characteristic absorption peaks, and a main peak in the range of 1.5 to 9.0 μm can be selected as its infrared characteristic absorption peak λ g Generally speaking, the smaller the value, the higher the target temperature value required to be achieved by the second electric heating rod coated with the selective coating, which can be combined with the reaction temperature T r Make further reasonable choices;

[0055] Step 2: Determine the target temperature T of the thermal radiation source e2 According to Wien's displacement law, a black body has a wavelength of λ m =b / T, where the peak of the monochromatic radiation force is located. b is a constant, b = 2897.8K·μm. Based on this, the target temperature T that the second electric heating rod 10 coated with the selective coating needs to reach is calculated. e2 =b / λ g, to achieve the matching between the thermal radiation source and the infrared characteristic absorption peaks of reactant gas molecules;

[0056] Step 3.

[0057] Step 4. According to the solved target temperature T e2 of the thermal radiation source and the target value I r ' of the radiation intensity in the reaction region,推算 the diameter D of the second electric heating rod 10 coated with the selective coating; Assume the length of the second electric heating rod 10 is l, the distance from the reaction region to the central axis of the second electric heating rod 10 is r, the emissivity of the selective coating is ε, and the transmittance of the quartz glass 8 is τ; According to the Stefan-Boltzmann law, through integral calculation in the range of space 0 < θ < 2 and length 0 < z < l, derive the correlation formula between the target value I r ' of the radiation intensity and the axial distance r:

[0058]

[0059] where σ is the Stefan-Boltzmann constant, with a value of 5.67×10 -8 [[ID=3!]]W / (m 2 ·K), Substitute all known quantities into the above formula to推算 and determine the diameter D of the second electric heating rod 10 coated with the selective coating, θ is the direction angle, and z is the distance in the length l direction;

[0060] Step 5. Debug the reaction device according to the solved control parameters; For the second electric heating rod 10 coated with the selective coating, determine the model of the second electric heating rod 10 according to the calculated diameter D, and set the optimal temperature it needs to reach according to the target temperature T e2 of the thermal radiation source, so as to achieve the regulation of thermal radiation energy; For the first electric heating rod 5, set its electric power according to the target value T r ' of the reaction temperature, and make dynamic adjustments according to the actual reaction rate.

[0061] Working principle and process:

[0062] Unlike traditional thermal catalysis, which relies primarily on thermal power as a control condition, the activation of thermal radiation catalysis requires two specific energy conditions: thermal energy, expressed as the reaction temperature, which is primarily controlled by the first electric heater; and thermal radiation energy, expressed as the radiation wavelength and intensity, which is primarily controlled by the second electric heater coated with a selective coating. These control parameters can all be calculated using the method provided by this invention.

[0063] Raw gas inlet 1, multiple inlets can be added according to reaction requirements.

[0064] Gas pipeline 2 is used for heat recovery and preheating the raw gas within the pipeline. It can be made of a metal with high thermal conductivity (such as copper). This gas pipeline paved the entire interior of the reactor shell to absorb excess heat and reduce external heat loss from the shell. Furthermore, this gas pipeline passes through the gas outlet channel (without affecting the outflow of product gas) to recover high-temperature gas at the outlet and preheat the raw gas within the pipeline.

[0065] The reaction device housing 3 plays a supporting and protective role and can be made of materials such as stainless steel.

[0066] The heat insulation layer 4 plays the role of heat preservation and heat insulation, and can be made of materials such as Al2O3 ceramics, polyurethane foam, and asbestos.

[0067] The first electric heating rod 5 is used to provide a heat source and control the reaction temperature in real time. Its target value is determined by the optimal temperature required for different reaction types. The specific calculation steps are provided in the subsequent method. Metals (such as copper, stainless steel, aluminum alloy, etc.) and non-metallic materials (such as ceramics, graphite, etc.) can be selected. It can also be combined with components such as thermocouples to form a negative feedback control function for temperature.

[0068] The thermal conductive layer 6 is a low-emissivity metal thermal conductive layer, which needs to have both low emissivity and high thermal conductivity. A high-thermal conductivity metal with a polished surface (such as stainless steel, nickel-aluminum alloy, etc.) or a graphite material (such as graphene) can be selected. Its function is to transfer the heat energy generated by the first electric heating rod 5 to the reaction area below through heat conduction, while isolating the thermal radiation generated by the first electric heating rod 5 due to high temperature and reducing the thermal radiation generated by itself.

[0069] The high-temperature porous reaction layer 7 is the primary site for the thermal radiation catalytic reaction, receiving both the high temperature from the first electric heating rod 5 and the thermal radiation energy from the second electric heating rod 10 coated with a selective coating. The substrate is a reticular porous material, which can be made of porous metal or foam ceramic with a through-hole structure, and its surface is coated with the catalyst material required for the reaction. It should be noted that the long length of the entire reaction zone is used to ensure uniformity of the temperature field; the small thickness is used to ensure that the radiation energy can be distributed throughout the entire area (thermal radiation energy decays rapidly in porous media).

[0070] The quartz glass 8 is a high-temperature resistant quartz glass with high infrared transmittance. It needs to have high transmittance and high-temperature resistance to radiation energy in the infrared band (>0.76μm). Its main function is to divide the high-temperature porous reaction layer 7 and the reaction gas premixing chamber 9, and to transmit the thermal radiation energy emitted by the second electric heating rod 10 coated with the selective coating to the high-temperature porous reaction layer 7.

[0071] The reaction gas premixing chamber 9 is where the various raw material gases transported by the gas pipeline 2 are mixed and, after being preliminarily heated by the second electric heating rod 10 coated with a selective coating, are transported to the high-temperature porous reaction layer 7 to participate in the reaction.

[0072] The second electric heating rod 10 coated with a selective coating has the main function of providing thermal radiation energy. The radiation band is controlled by selective coating (directly changing the emissivity of each band) or adjusting the electric power (adjusting its own temperature to change the peak wavelength); the radiation intensity (energy density) is controlled by changing the diameter of the second electric heating rod 10. The above control parameters will be given by the calculation method proposed in the present invention according to the reaction type. The selective coating material adopts a ceramic-based material with high emissivity in the infrared band (such as cordierite, zircon sand, silica, etc.) or a high-temperature resistant metal or metal oxide coating material (such as cerium oxide, zirconium oxide, yttrium oxide, etc.). The material selection of the second electric heating rod 10 refers to the first electric heating rod 5.

[0073] A water cooling pipeline can be added to the gas product outlet 11 to cool it to room temperature for easy collection; a heat recovery pipeline can also be further added to improve energy efficiency.

[0074] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Any changes or substitutions within the technical concepts disclosed in the present application and any changes or substitutions based on the technical solutions of the present application shall fall within the scope of protection of the present application.
