Description

Technical Field

[0001] The present invention relates to a hydrogen decomposition device and a hydrogen decomposition method using the hydrogen decomposition device. Background Art

[0002] In the operation of changing the ammonia decomposition amount according to the state of the running vehicle, the ammonia supply amount may be controlled differently according to the temperature of the reactor to stabilize the ammonia decomposition rate in the reactor due to the change in the reactor temperature.

[0003] During such load-following operation, if the amount of ammonia supplied to the reactor is increased to increase hydrogen production in a short period of time, the temperature inside the reactor will drop because the temperature of the supplied ammonia is generally room temperature. That is, the degree of temperature drop can be determined by the flow rate of ammonia.

[0004] If the temperature inside the reactor decreases temporarily, the ammonia decomposition rate decreases due to the deactivation of the catalyst inside the reactor or the overall performance of the device. As a result, the amount of residual ammonia in the device may increase. Since the residual ammonia is supplied to the adsorption tower or fuel cell, it may cause the overall performance of the device to decrease or unexpected failure. Summary of the invention

[0043] Reference Figure 1 , the hydrogen decomposition device 10 includes a reactor 100, an absorption unit 200, a fuel cell 300 and a heating unit 400. Each configuration / node can send and receive data with other configurations / nodes. Each configuration / node can be connected through a network. According to an exemplary embodiment, the hydrogen decomposition device 10 may include a dual heating mechanism or a dual heating device as will be described later.

[0044] The hydrogen decomposition device 10 may receive ammonia (NH3) through the reactor 100 and decompose it. If the temperature inside the reactor 100 temporarily decreases, the ammonia decomposition rate may decrease due to deactivation or performance degradation of the catalyst inside the reactor 100. Therefore, the amount of residual ammonia in the reactor 100 may increase relatively.

[0045] According to an exemplary embodiment, the reactor 100 may receive ammonia and generate hydrogen (H2), nitrogen (N2), and ammonia (NH3) as decomposition products. Then, each fluid absorbed by the absorption unit 200 may be supplied to the fuel cell 300 and used for power supply of the battery.

[0046] According to an exemplary embodiment, the fuel cell 300 may supply nitrogen and unconverted hydrogen, etc. to the heating unit 400 before resupplying the nitrogen and unconverted (unreacted) hydrogen, etc. to the reactor 100, so that the unconverted hydrogen can be completely burned. Therefore, the hydrogen decomposition device 10 can re-burn the byproducts generated due to the imbalance of the materials supplied to the reactor 100 through feedback. The heat generated in the heating unit 400 can be used to adjust the internal temperature of the reactor 100 to maintain a suitable high temperature for the ammonia decomposition reaction in the reactor 100.

[0047] After the combustion reaction in the heating unit 400 , flue gas may be exhausted.

[0054] According to an exemplary embodiment, the driving unit 110 may be driven by power supplied by a battery. For example, the driving unit 110 may adjust the power supplied to the heating unit 400 based on a signal received from the control unit 120. Thus, the control signal from the control unit 120 may be converted into a specific power level required to drive the heating unit 400. The reactor 100 may decompose ammonia to produce hydrogen, and the heating unit may heat the reactor 100 and / or heat the hydrogen and ammonia to be supplied into the reactor 100. Therefore, the driving unit 100 may serve as an intermediate control unit between the control unit 120 and the reactor 100.

[0055] For example, the heating unit may include an electric heater. The heating unit may run through the reactor 100, be connected to the reactor 100, or surround the reactor 100.

[0066] In step S310, a control unit (eg, Figure 2 The control unit 120 may receive the power consumption information of the battery. The control unit 120 may confirm the power consumption information consumed in the battery and decompose a predetermined amount of ammonia in the reactor 100 of the hydrogen decomposition device 10 to increase or decrease the hydrogen supplied to the fuel cell 300.

[0067] In one embodiment, the control unit 120 may confirm the power consumption information of the battery from the storage unit to control the amount of ammonia supplied to the reactor 100. In one embodiment, the control unit 120 may confirm the power consumption information of the battery from a battery management system (BMS) that may confirm the life of the battery, the service life of the battery, and the real-time power consumption rate of the battery, etc.

[0068] In step S320, the control unit 120 may supply a portion of the power in the battery to the heating unit. The control unit 120 may confirm that the heating unit is driven (eg, Figure 1 The control unit 120 may determine the estimated power consumption of the heating unit when the reactor (eg, Figure 1 The control unit 120 can calculate the expected temperature rise value when the fuel cell (for example, Figure 1 A portion of the electricity in the battery supplied by the fuel cell 300 is supplied to the heating unit.

[0069] In one embodiment, the control unit 120 may supply a portion of the power supplied from the battery to the hydrogen decomposition device to the heating unit, and may control the operation of the heating unit in consideration of the state of the battery and the temperature inside the reactor.

[0070] In step S330, the control unit 120 may detect the power consumption of the battery based on the power consumption information of the battery and the power consumption information of the battery through the sensor unit (eg, Figure 2 The operation of the heating unit is controlled by using the internal temperature information of the reactor collected by the sensor unit 130. For example, in the load tracking state of the hydrogen decomposition device, the control unit 120 can calculate the expected power consumption of the heating unit and the expected temperature rise value of the reactor. Therefore, the control unit 120 can determine whether to drive the heating unit and the operation intensity of the heating unit, etc., considering the reaction efficiency that can be expected due to the temperature rise of the reactor.

[0071] Figure 4 is a schematic flowchart for explaining driving of a heating unit of a hydrogen decomposition method according to an exemplary embodiment of the present disclosure.

[0072] Reference Figure 4 In step S410, the control unit 120 may receive the injection amount information and the injection time information of ammonia. For example, the control unit 120 receives the injection amount information and the injection time information of ammonia from a flow meter that senses the injection amount of ammonia. The heating unit may be controlled by information related to the amount of ammonia injected into the reactor and the injection time.

[0073] In step S420, the control unit 120 may calculate the injection rate of ammonia. For example, the control unit 120 may calculate the injection rate of ammonia based on the injection amount information and injection time information of ammonia received in step S410.

[0074] In step S430, the control unit 120 may calculate the expected temperature rise value of the reactor based on the injection speed of ammonia. For example, the control unit 120 may calculate the expected temperature rise value expected when driving the reactor by the speed at which ammonia is injected into the reactor. For example, the control unit 120 may perform calculation based on information storing experimental values ​​of the expected temperature rise value corresponding to the injection speed of ammonia.

[0075] In step S440, the control unit 120 may calculate the injection acceleration of ammonia. For example, the control unit 120 may calculate the acceleration based on the injection speed of ammonia.

[0076] In step S450, when the injection acceleration of ammonia is greater than or equal to the preset acceleration, the control unit 120 may drive the heating unit. For example, when the acceleration calculated by the injection speed of ammonia is greater than or equal to the preset acceleration, the control unit 120 may immediately start the heating unit to increase the temperature inside the reactor.

[0077] The control unit 120 controls the operation of the heating unit according to the reference conversion rate within the range in which the operation of the heating unit is advantageous in terms of energy efficiency by comparing the predicted temperature rise value with the predicted power consumption of the heating unit. For example, the reference conversion rate information and the preset acceleration information may be stored in the storage unit. For example, the reference conversion rate may be similar to the reaction efficiency.

[0078] The control unit 120 can control the operation of the heating unit based on the reference conversion rate information corresponding to the experimental value and the preset acceleration information. Therefore, the operation of the heating unit can be controlled by comparing the gain generated by the predicted temperature rise value of the reactor with the amount of power consumed by the operation of the heating unit in real time.

[0081] According to an exemplary embodiment, a control unit (eg, Figure 2 The control unit 120 of the reactor 100 may control the operation of at least one tube included in the heating unit 400. In one embodiment, the temperature information of the first part and the temperature information of the second part in the reactor 100 may be confirmed. The control unit 120 may control the tube of the heating unit 400 adjacent to the first part and the tube of the heating unit 400 adjacent to the second part differently.

In addition, the control unit 120 can optimize the reaction efficiency by using a portion of the power consumption of the battery to drive the heating unit.

[0088] The driving of the heating unit can be performed by calculation to meet the set ratio of the power consumption of the battery and the expected temperature rise value of the reactor by the heating unit. That is, the control unit 120 can utilize the structural aspects according to the settings of the battery and the heating unit and the energy allocation aspects of utilizing a part of the power consumption of the battery.

In one embodiment, the heating unit is disposed around the ammonia injection unit to heat the ammonia injected into the reactor before injecting the ammonia. The heating unit may include a plurality of pipes disposed adjacent to the ammonia injection unit.

[0090] The control unit 120 can improve the reaction efficiency in the reactor by heating the ammonia before injecting it. Therefore, the temperature inside the reactor can be raised by the heating unit, and the temperature inside the reactor can be prevented from decreasing by preheating the ammonia as a reactant. Therefore, the temperature of the reactor can be directly increased by the heating unit, so that the ammonia decomposition rate can be increased. In addition, the amount of residual ammonia can be reduced by maintaining the temperature inside the reactor at a preset temperature.
