DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of this application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle within the range of 80° to 100° is considered vertical. Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0063] The applicant noted that with the advancement of greenhouse gas emission reduction strategies, the demand for ship carbon emission reduction has become increasingly prominent. In recent years, the use of LNG (liquefied natural gas) fuel has become a trend, resulting in an annual increase in the number of LNG-powered ships. However, with the implementation of phased carbon reduction indicators, the limited carbon reduction of LNG-powered ships is difficult to meet future carbon emission reduction needs.

[0064] In the face of the carbon dioxide emissions from the combustion of LNG fuel on ships, carbon capture technology is an effective means to achieve ship decarbonization, but the more mature back-end carbon capture technology currently has problems such as high energy consumption and large equipment footprint. In recent years, LNG fuel-end decarbonization technology has developed rapidly with its advantages of low energy consumption and compact structure, becoming a feasible path to extend the vitality of LNG-powered ships. This technology decarbonizes and captures the fuel before it is burned through reactions such as methane reforming or cracking. The decarbonized zero-carbon hydrogen fuel enters the cylinder for combustion, thereby achieving carbon emission reduction for the entire ship.

[0065] The high-temperature and high-pressure reactor is the core equipment of the entire ship's LNG fuel efficient decarbonization system. The raw gas collection chamber is responsible for distributing the mixed raw gas entering the furnace to the conversion tube. The conversion tube completes the conversion reaction of natural gas through the action of the loaded catalyst bed. The combustion chamber is the area where the fuel and air are mixed and burned. The high-temperature flue gas generated by the combustion in the combustion chamber heats the conversion tube, which increases the temperature of the catalyst bed in the conversion tube and provides heat for the catalytic conversion reaction in the tube.

[0066] However, due to the limitations of the ship's operating environment, the ship's LNG fuel efficient decarbonization system needs to be compact, modular, and intelligent, while also meeting the requirements of low energy consumption and high conversion efficiency. It requires continuous updating, iteration, and optimization of the reactor and the catalysts used inside.

[0067] In view of this, an embodiment of the present application provides a testing device for testing and evaluating catalysts of different process routes, high-temperature and high-pressure reactors of different structures, and reaction tube sections of a marine high-temperature and high-pressure reaction device.

[0068] For details, please refer to Figure 1-Figure 6 A test device according to an embodiment of the present application comprises a reaction unit 1, a pilot gas supply unit 2, an air supply unit 3, a fuel gas supply unit 4, a reaction gas supply unit 5, a synthesis gas output unit 6 and a smoke gas output unit 7; the reaction unit 1 comprises a shell 11, a reaction pipeline 12 and a burner 13; the shell 11 has a receiving cavity 111, at least part of the reaction pipeline 12 is arranged in the receiving cavity 111 and connected to the shell 11, and the burner 13 is connected to the shell 11 for providing heat to the reaction pipeline 12 located in the receiving cavity 111; the pilot gas supply unit 2 It is connected to the burner 13 and is used to provide pilot gas to the burner 13; the air supply unit 3 is connected to the burner 13 and is used to provide air to the burner 13; the fuel gas supply unit 4 is connected to the burner 13 and is used to provide fuel gas to the burner 13; the reaction gas supply unit 5 is connected to the reaction pipeline 12 and is used to provide reaction gas to the reaction pipeline 12; the synthesis gas output unit 6 is connected to the reaction pipeline 12 and is used to receive and detect the synthesis gas output by the reaction pipeline 12; the smoke output unit 7 is connected to the shell 11 and is used to receive and detect the smoke exhausted from the accommodating cavity 111.

[0069] The present application can simplify the device structure by setting up independent reaction units 1, pilot gas supply units 2, air supply units 3, fuel gas supply units 4, reaction gas supply units 5, synthesis gas output units 6 and flue gas output units 7. When testing, the various units are directly connected to achieve rapid construction of the test device, and corresponding raw material supply units can be connected according to different test scenarios to achieve the construction of different test scenarios.

[0070] It should be noted that the present application sets up multiple raw material supply raw materials to be connected to the reaction unit 1, and sets up a synthesis gas output unit 6 and a flue gas output unit 7 at the output end of the reaction unit 1. At the same time, different catalysts 8 can be set in the reaction pipeline 12. On the one hand, different raw materials can be input according to test requirements to realize the catalytic reaction in the reaction unit 1. On the other hand, the synthesis gas output unit 6 and the flue gas output unit 7 are used to detect the synthesis gas after the reaction and the flue gas generated in the containing chamber 111, so as to test and evaluate the performance of the entire constructed reaction system and evaluate the catalytic performance corresponding to different catalysts 8.

[0071] Specifically, in the embodiment of the present application, the reaction unit 1 can be a high-temperature and high-pressure reactor; the shell 11 is heat-insulated and heat-preserved, and the accommodating chamber 111 in the shell 11 is used to accommodate the reaction pipeline 12 and to provide a high-temperature environment to maintain the high-temperature state of the reaction pipeline 12; the reaction pipeline 12 can be used to supply the raw gas for catalytic reaction, and at this time, a catalyst 8 bed is placed in the reaction pipeline 12 to achieve the catalytic reaction of the raw gas; the burner 13 is used to burn the fuel to provide heat energy to enter the accommodating chamber 111. The pilot gas supply unit 2 is connected to the input end of the burner 13, and is used to provide pilot gas for the ignition of the burner 13 to ensure that the fuel gas burns smoothly in the burner 13. The air supply unit 3 is connected to the input end of the burner 13, and is used to continuously provide air to the burner 13, mainly to provide oxygen to assist combustion. The fuel gas supply unit 4 is connected to the input end of the burner 13, and is used to continuously provide fuel to the burner 13 after the burner 13 is ignited; specifically, when the burner 13 is successfully ignited, the fuel gas supply unit 4 is opened to input the fuel gas, and then the pilot gas supply system is closed, so that the fuel gas passes through the burner 13 and burns in the accommodating chamber 111. The reaction gas supply unit 5 is connected to the input end of the reaction pipeline 12, and is used to continuously input the reaction gas into the reaction pipeline 12. The reaction gas contacts the catalyst 8 in the reaction pipeline 12 to achieve a catalytic reaction to produce the target synthesis gas. The synthesis gas output unit 6 is connected to the output end of the reaction pipeline 12, and is used to lead out the target synthesis gas produced after the catalytic reaction of the reaction pipeline 12 and detect related parameters. The smoke output unit 7 is used to lead out the smoke generated by the combustion of the fuel gas in the accommodating chamber 111 and perform detection and subsequent carbon removal treatment.

[0072] It should be noted that the burner 13 of the embodiment of the present application can be directly arranged in the accommodating chamber 111, or at least its output end is located in the accommodating chamber 111, so as to ensure that the burner 13 can be ignited in the accommodating chamber 111 and finally burn the fuel gas. At the same time, the reaction unit 1 can be provided with multiple burners 13, and the multiple burners 13 are distributed in different positions of the accommodating chamber 111, so that the fuel gas can be ignited and burned at multiple points, ensuring that the temperature inside the accommodating chamber 111 of the reaction unit 1 is evenly distributed. At the same time, it can achieve the desired temperature quickly.

[0073] Furthermore, in some embodiments, the reaction gas supply unit 5 includes a water vapor supply unit 52 , which is connected to the reaction pipeline 12 and is used to test and evaluate the thermal performance of the reaction unit 1 .

[0074] In an embodiment of the present application, the reaction unit 1 of the test device is combined with each raw material supply unit in different ways, and the input and output of each supply unit are controlled at the same time, or different reaction units 1 are replaced, so that different test evaluation scenarios can be achieved.

[0075] Please refer to Figure 1 and Figure 4 Specifically, when the pilot gas supply unit 2, the air supply unit 3, the fuel gas supply unit 4, the water vapor supply unit 52, the synthesis gas output unit 6 and the flue gas output unit 7 are connected to the reaction unit 1, the testing device is used to evaluate the thermal performance of the reaction unit 1. At this time, the thermal performance of the reaction unit 1 is detected by continuously introducing water vapor into the reaction pipeline 12.

[0076] When the test device is in the thermal performance evaluation mode, there is no catalyst 8 in the reaction pipeline 12, and the input end of the reaction pipeline 12 is connected to the water vapor supply unit 52, which continuously generates water vapor through the steam generator 521 and supplies it to the reaction pipeline 12, and uses water vapor as a heat exchange medium to test the thermal performance of the reaction unit 1. Specifically, according to the heating capacity of the reaction unit 1, the steam generator 521 in the water vapor supply unit 52 is used to control the temperature, pressure, flow rate and other parameters of the saturated water vapor entering the input end of the reaction pipeline 12; when the synthesis gas output unit 6 detects a stable water vapor flow rate, the burner 13 is started to ignite the gas supply unit 2 and the air supply unit 3, and the burner 13 of the reaction unit 1 is ignited. After ignition, the combustion gas supply unit is switched to keep the heat supply to the burner 13. After the test device is running stably, the smoke output unit 7 is used to test the smoke composition, temperature and pressure of the smoke discharged from the containing chamber 111, and the synthesis gas output unit 6 is used to test the temperature and pressure of the water vapor discharged from the output end of the reaction pipeline 12, and the enthalpy difference of the water vapor at the input and output ends of the reaction pipeline 12, as well as the enthalpy difference between the smoke in the containing chamber 111 and the smoke at the inlet of the smoke output unit 7 are calculated, and then the heat transfer efficiency and other parameters of the reaction unit 1 are obtained. The data test is repeated by changing multiple common working conditions, and then the thermal performance of the reaction unit 1 is evaluated through comparative analysis, so as to select the reaction unit 1 with high heat transfer efficiency, uniform temperature distribution and high temperature area that meets the reaction requirements.

[0077] like Figure 4 As shown, further, in some embodiments, the water vapor supply unit 52 includes: a deionized water supply structure 525, a steam generator 521, a first transmission pipeline 522, a first flow meter 523, a first pressure sensor 524, a first solenoid valve 526 and a metering pump 527; wherein the deionized water supply structure 525 is used to provide deionized water; the steam generator 521 is connected to the deionized water supply structure 525, and is used to convert deionized water into water vapor; the first transmission pipeline 522 is connected to the steam generator 521, and is used to convert water vapor into water vapor. The gas is transmitted to the reaction pipeline 12; the first flow meter 523 is connected to the first transmission pipeline 522, and is used to detect the flow rate of water vapor in the first transmission pipeline 522; the first pressure sensor 524 is connected to the first transmission pipeline 522, and is used to detect the pressure of water vapor in the first transmission pipeline 522; the first solenoid valve 526 is connected to the first transmission pipeline 522, and is used to control the opening and closing of the first transmission pipeline 522; the metering pump 527 is connected between the steam generator 521 and the deionized water supply structure 525, and is used to measure the supply of deionized water.

[0078] Specifically, when conducting the test evaluation, the deionized water supply structure 525 is first opened and the deionized water is delivered to the steam generator 521. The metering pump 527 is used to measure the amount of deionized water input, and then the deionized water passes through the steam generator 521 to generate water vapor and is delivered to the reaction pipeline 12. During this period, the first flow meter 523 is used to measure the output water vapor flow rate, and the first pressure sensor 524 is used to measure the pressure in the first transmission pipeline 522, which is convenient for the subsequent thermal performance evaluation. In addition, the water vapor supply unit 52 is also provided with a first electromagnetic valve 526, which is used to directly cut off or open the water vapor supply during the test process to ensure safety and avoid waste of water vapor.

[0079] Please refer to Figure 2 and Figure 3 In some embodiments, the reaction gas supply unit 5 further includes a natural gas supply unit 51 , and a catalyst 8 is disposed in the reaction pipeline 12 ; the natural gas supply unit 51 is connected to the reaction pipeline 12 for testing and evaluating the performance of the catalyst 8 .

[0080] It should be noted that when the test device is used to evaluate the performance of the catalyst 8, the catalyst 8 of the decarbonization reaction at the fuel end can be tested and evaluated. At this time, the reaction pipeline 12 is provided with a corresponding catalyst 8 that needs to be tested and evaluated for performance, and the natural gas supply unit 51 is connected to the input end of the reaction pipeline 12 to continuously input the reaction gas into the reaction pipeline 12, thereby achieving natural gas decarbonization.

[0081] In the embodiment of the present application, the fuel gas may also be natural gas. After the system is built, the pilot gas supply unit 2 and the air supply unit 3 are started to ignite the burner 13 of the reaction unit 1. After ignition, the combustion gas supply unit is switched to keep the heat supply to the burner 13. After the temperature in the reaction pipeline 12 is stabilized, the reaction gas supply unit 5 is turned on, and the reaction gas is input into the reaction pipeline 12, wherein the water vapor supply unit 52 continuously inputs water vapor, and the natural gas supply unit 51 continuously inputs natural gas, and the input amount during the process is recorded; after the test device is stably operated, the smoke output unit 7 is used to test the smoke composition, temperature, and pressure of the smoke discharged from the accommodating chamber 111, and the synthesis gas output unit 6 is used to test the temperature and pressure of the synthesis gas discharged from the output end of the reaction pipeline 12, and the synthesis gas output unit 6 also includes a heat exchange component (specifically, it can be circulating water cooling), the synthesis gas is cooled down, and then the components of the cooled synthesis gas are analyzed to obtain the hydrogen concentration in the reaction pipeline 12. By setting different input and output modes for each unit, changing various operating conditions (material input amount and temperature adjustment, etc.), or replacing the catalyst 8 for repeated testing, as well as conducting tests and hydrogen concentration detection in different time periods, the efficiency and service life of the catalyst 8 under different operating conditions are analyzed and calculated, thereby evaluating the performance, operating temperature space, service life and other indicators of different types of catalysts 8, and then screening out catalysts 8 that meet the reaction requirements.

[0082] It should be noted that natural gas and water vapor are simultaneously input into the reaction pipeline 12 , and methane and water vapor undergo a catalytic reaction on the catalyst 8 to produce hydrogen.

[0083] It should also be noted that when the testing device is evaluating the performance of the catalyst 8, different types of catalysts 8 can be replaced in the reaction pipeline 12 according to the test needs. By making the catalyst 8 replaceable, it is possible to test and evaluate different types of catalysts 8.

[0084] In addition, the testing device of the present application can also perform structural performance test and evaluation of the reaction unit 1. At this time, the reaction unit 1 in the catalyst 8 performance test mode is replaced, and the others remain unchanged. The input and output operating conditions of each unit are adjusted, as well as the temperature in the containing chamber 111. The various parameters of the flue gas of the flue gas output unit 7 under various operating conditions, as well as the synthesis gas at the synthesis gas output unit 6, are tested. The structural performance test and evaluation of the reaction unit 1 can be achieved through analysis and calculation.

[0085] Of course, since the difference in the structure of the reaction unit 1 is mainly reflected in the reaction pipeline 12 , the effect of replacing the reaction unit 1 can be achieved by replacing the reaction pipeline 12 in the reaction unit 1 .

[0086] Furthermore, the testing device of the present application can also test and evaluate the performance of various decarbonization processes. The specific testing and evaluation architecture is the same as the architecture of the catalyst 8 performance testing and evaluation, and will not be repeated here.

[0087] like Figure 3 As shown, in some embodiments, the natural gas supply unit 51 includes a natural gas supply structure 511, a natural gas temporary storage tank 512, a second transmission pipeline 513, a second flow meter 514, a second pressure sensor 515 and a second solenoid valve 516; wherein the natural gas supply structure 511 is used to provide natural gas; the natural gas temporary storage tank 512 is connected to the natural gas supply structure 511 for temporarily storing natural gas; the second transmission pipeline 513 is connected to the natural gas supply structure 511 for transmitting natural gas to the reaction pipeline 12; the second flow meter 514 is connected to the second transmission pipeline 513 for detecting the flow of natural gas in the second transmission pipeline 513; the second pressure sensor 515 is connected to the second transmission pipeline 513 for detecting the pressure of natural gas in the second transmission pipeline 513; the second solenoid valve 516 is connected to the second transmission pipeline 513 for controlling the opening and closing of the second transmission pipeline 513.

[0088] In the embodiment of the present application, when the performance test and evaluation of the catalyst 8 is performed, the burner 13 is first ignited to heat the reaction unit 1.
