Description

Technical Field

[0001] The invention belongs to the technical field of organic liquid dehydrogenation, and in particular relates to an organic liquid dehydrogenation integrated reactor and system. Background Art

[0002] Hydrogen storage is a very important part of the hydrogen economy. People have developed a variety of hydrogen storage technologies, such as high-pressure hydrogen storage, liquid hydrogen storage, solid hydrogen storage, and organic hydrogen carrier hydrogen storage. Organic liquid hydrogen carrier technology (hereinafter referred to as LOHC) uses specific organic compounds such as dibenzyltoluene (DBT), benzyltoluene (MBT), N-ethylcarbazole, toluene, methanol, etc. as carriers to achieve hydrogen storage and release through reversible catalytic hydrogenation and dehydrogenation reactions. During the hydrogenation process, hydrogen is chemically combined with organic molecules to form hydrides (such as fully hydrogenated dibenzyltoluene, H 18 -DBT). During the dehydrogenation process, hydrogen is released from the hydride and the organic molecule returns to its original state.

[0003] Currently, most organic liquid hydrogen storage and decomposition equipment still uses independent reactors. This results in complex system integration of the entire equipment, large amounts of catalysts used and high costs, the need for a complex thermal management system to provide the heat transfer required by the reactor, difficulty in improving energy utilization, complex safety control strategies, difficulty in optimizing the space and layout of system integration design, and complex maintenance and overhaul.

[0016] The heat transfer oil thermal management module is connected to the heat transfer oil inlet and the heat transfer oil outlet respectively;

[0017] In the hydrogenation mode, the dehydrogenated organic liquid storage tank is connected to the shell side inlet of the heat exchange module through the liquid inlet pump and the flow control module, the shell side outlet of the heat exchange module is connected to the LOHC inlet at the top of the organic liquid dehydrogenation integrated reactor, the LOHC liquid port at the bottom of the organic liquid dehydrogenation integrated reactor is connected to the tube side inlet of the heat exchange module, the tube side outlet of the heat exchange module is connected to the hydrogen-containing organic liquid storage tank, the hydrogen supply module is connected to the first hydrogen port, and the second hydrogen port at the bottom of the organic liquid dehydrogenation integrated reactor is also connected to the first hydrogen port;

After preheating, it enters the lower head of the reactor through the LOHC liquid port, passes through the pores of the sieve plate, and enters the reaction tube, flowing from bottom to top;

[0021] LOHC+ conducts dehydrogenation reaction on a fixed catalyst bed, controls the mass flow rate through the liquid inlet pump and flow control module, and controls the reaction temperature through the heat transfer oil thermal management module to comprehensively control the dehydrogenation rate;

[0044] A sieve plate 125 is disposed at the bottom of the reactor housing 103, and the aperture of the sieve plate 125 is smaller than the diameter of the catalyst 121 carrier, so as to prevent the catalyst 121 from leaking and allow the LOHC to pass through;

Through the cooperation of the sensors, the internal liquid level, temperature and pressure can be monitored in real time.

[0050] like Figure 1 and 2As shown, an organic liquid dehydrogenation integrated reaction system provided by another embodiment of the present invention is based on the above-mentioned organic liquid dehydrogenation integrated reactor, including an organic liquid dehydrogenation integrated reactor, and also includes a hydrogen-containing organic liquid storage tank 1, a liquid inlet pump and flow control module 2, a heat exchange module 3, a gas-liquid separation module 4, a dehydrogenated organic liquid storage tank 5, a hydrogen module 6, a heat transfer oil thermal management module 7 and a hydrogen supply module 8;

[0051] The heat transfer oil thermal management module 7 is connected to the heat transfer oil inlet 118 and the heat transfer oil outlet 117 respectively;

[0052] In the hydrogenation mode, the dehydrogenated organic liquid storage tank 5 is connected to the shell side inlet of the heat exchange module 3 through the liquid inlet pump and the flow control module 2, the shell side outlet of the heat exchange module 3 is connected to the LOHC inlet 105 at the top of the organic liquid dehydrogenation integrated reactor, the LOHC liquid port 109 at the bottom of the organic liquid dehydrogenation integrated reactor is connected to the tube side inlet of the heat exchange module 3, the tube side outlet of the heat exchange module 3 is connected to the hydrogen-containing organic liquid storage tank 1, the hydrogen supply module 8 is connected to the first hydrogen port 106, and the second hydrogen port 108 at the bottom of the organic liquid dehydrogenation integrated reactor is also connected to the first hydrogen port 106;

[0053] In the hydrogen release mode, the hydrogen-containing organic liquid storage tank 1 is connected to the shell side inlet of the heat exchange module 3 through the liquid inlet pump and the flow control module 2, the shell side outlet of the heat exchange module 3 is connected to the LOHC liquid port 109 at the bottom of the organic liquid dehydrogenation integrated reactor, the LOHC outlet 107 at the top of the organic liquid dehydrogenation integrated reactor is connected to the tube side inlet of the heat exchange module 3, the tube side outlet of the heat exchange module 3 is connected to the gas-liquid separation module 4, and the gas-liquid separation module 4 is simultaneously connected to the dehydrogenated organic liquid storage tank 5 and the hydrogen module 6.

[0054] like Figure 1 As shown, as a preferred embodiment of the present invention, in the hydrogenation mode, LOHC-(HO-DBT, i.e., dehydrogenated organic liquid) and hydrogen flow from top to bottom (downflow mode), and LOHC- in the dehydrogenated organic liquid storage tank 5 enters the shell side space of the heat exchange module through the liquid inlet pump and the flow control module 2, and exchanges heat with the high-temperature fluid in the tube side, and enters the liquid inlet distributor 120 from the LOHC inlet 105 on the reactor upper head 101 after preheating; hydrogen in the hydrogen supply module 8 enters the reactor upper head 101 through the first hydrogen port 106, and hydrogen and LOHC- are mixed in the internal environment of the reactor upper head 101, and flow downward through the catalyst fixed bed in the reaction tube 122; when the catalyst fixed bed undergoes hydrogenation reaction, a large amount of heat is released, and the heat transfer oil is controlled by the heat transfer oil thermal management module 7 to meander along the baffle 123 in the reactor shell 103 to take away the reaction heat. This mode helps to manage the temperature peak caused by the exothermic characteristics of hydrogenation and reduce the generation of hot spots; the product LOHC+(H18 -DBT, i.e., hydrogen-containing organic liquid) flows out of the reactor through the LOHC liquid port 109, enters the tube side space of the heat exchange module 3, and is then collected into the hydrogen-containing organic liquid storage tank 1 through the pipeline.

[0055] Through the heat exchange of the heat exchange module 3, the LOHC- can be preheated before entering the reactor, reducing the temperature fluctuation during the hydrogenation reaction and improving the energy utilization efficiency.

[0056] like Figure 2 As shown, as a preferred embodiment of the present invention, in the hydrogen release mode, the LOHC+ in the hydrogen-containing organic liquid storage tank 1 enters the shell side space of the heat exchange module 3 through the liquid inlet pump and the flow control module 2, and exchanges heat with the high-temperature fluid in the tube side, and after preheating, enters the reactor lower head 102 through the LOHC liquid port 109, and enters the reaction tube 122 through the pores of the sieve plate 125, and flows from bottom to top (upward flow mode);

[0057] LOHC+ performs dehydrogenation reaction in a catalyst fixed bed, controls the mass flow rate through the liquid inlet pump and flow control module 2, and controls the reaction temperature through the heat transfer oil thermal management module 7, so as to comprehensively control the dehydrogenation rate;

[0058] The reacted LOHC- flows out of the reactor through the LOHC outlet 107, enters the tube space of the heat exchange module 3, and then enters the gas-liquid separation module 4 through the pipeline. The hydrogen is separated from the gas-liquid separation module 4 and enters the hydrogen module 6 (fuel cell or hydrogen-fired engine) for use, while the LOHC- is recovered after separation and stored in the dehydrogenated organic liquid storage tank 5 for subsequent use.

[0059] As a preferred embodiment of the present invention, the specific process conditions of the hydrogenation mode are as follows:

[0060] a) Reactant preparation: The liquid organic hydrogen carrier (LOHC) used in the hydrogenation reaction is dibenzyltoluene (HO-DBT), and its hydrogenated form is fully hydrogenated dibenzyltoluene (H 18 -DBT).

[0061] b) Reactor: The reactor adopts an "integrated" design. When conducting the hydrogenation reaction, a downflow mode is adopted and the catalyst is Pt / Al2O3.

[0062] c) Hydrogenation reaction conditions: The hydrogenation process of the present invention is carried out at a relatively high temperature (usually between 240°C and 300°C) and pressure (about 3-6MPa). The reactor is temperature controlled by a thermal oil thermal management module 7 to ensure that the reaction is carried out under optimal conditions.

[0063] d) Hydrogen supply: The hydrogen required for hydrogenation mainly comes from compressed hydrogen, which can come from electrolyzers, industrial by-product hydrogen, etc. Hydrogen is transported to the reactor through pipelines to react with LOHC-(H0-DBT).

[0064] e) Reaction process: In the reactor, hydrogen reacts with LOHC-(HO-DBT) to generate LOHC+(H 18 -DBT), the reaction is an exothermic reaction, releasing heat, and the reaction temperature is also controlled by the thermal oil thermal management module 7.

[0065] f) Product separation: After hydrogenation reaction, the generated LOHC+(H 18 -DBT) are collected and stored in designated tanks. The gas and liquid in the reactor are separated, transferred or recycled through pipelines.

[0066] As a preferred embodiment of the present invention, the specific process conditions of the hydrogen release mode are as follows:

[0067] a) Reactant preparation: The reactant used in the dehydrogenation process is the hydrogenated LOHC+ (H 18 -DBT), which has a higher hydrogen content.

[0068] b) Reactor: The dehydrogenation process is also carried out in an "integrated" reactor, which adopts an upflow operation mode. The design of the reactor allows liquid and gas products to be discharged from the reactor head 101 together.

[0069] c) Dehydrogenation reaction conditions: During the dehydrogenation process, the temperature is usually between 260°C and 335°C, and the pressure is between 0.1 and 0.4 MPa. The temperature of the reactor is controlled by the thermal oil thermal management module 7.

[0070] d) Hydrogen release: In the dehydrogenation reaction, H 18 -DBT is converted into H0-DBT, releasing hydrogen. This reaction is an endothermic reaction, and the thermal oil thermal management module 7 also needs to provide additional heat to maintain the reaction.

[0071] e) Reaction process: The dehydrogenation reaction is promoted by the catalyst (Pt / Al2O3). 18 -DBT decomposes at high temperatures, releasing hydrogen and low-hydrogen-content LOHC-(H0-DBT).

[0072] f) Product separation: The generated hydrogen and LOHC-(HO-DBT) are discharged through the pipe and valve at the top of the reactor. They pass through the tube space of the heat exchange module 3, preheat the shell-side liquid inlet through heat exchange, and then enter the gas-liquid separation module 4. After hydrogen and LOHC-(HO-DBT) are separated in the gas-liquid separation module 4, hydrogen is then transported to the hydrogen module 6 (fuel cell or hydrogen-fired engine) for energy conversion, while LOHC-(HO-DBT) is recovered to the dehydrogenated organic liquid storage tank 5 for storage for subsequent use.

[0073] As a preferred embodiment of the present invention, in specific applications, the system can be integrated into a renewable energy storage device. Hydrogen generated by renewable energy such as wind energy and solar energy through a water electrolysis device is stored as an energy carrier through an integrated dehydrogenation reactor to achieve safe and long-term storage of hydrogen. Compared with traditional lithium battery energy storage, it has the characteristics of low investment and high safety.

[0074] Alternatively, the system can be integrated into a distributed energy system, with an integrated dehydrogenation reactor to provide storage and release of hydrogen, combined with a fuel cell cogeneration system or a hydrogen-fired engine system to provide a comprehensive supply of electricity, heat and kinetic energy.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
