[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The following reference Figures 1-5 This application describes an embodiment of a teaching tool for demonstrating the principle of methanol reforming.

[0020] A teaching aid for demonstrating the principle of methanol reforming includes a base 1, with a tubular heater 2 fixedly mounted on top of the base 1. A tubular reactor 3 is embedded inside the tubular heater 2. In practice, the tubular reactor 3 can be replaced with an acrylic pipe filled with a methanol reforming catalyst, allowing for more direct observation of the reactor's internal structure. The front of the base 1 is closed, while the back is an open cavity structure. This open cavity structure facilitates observation and allows for the filling and addition of liquid by a syringe 4. The syringe 4 is housed inside the base 1, and a stepper motor 5 is also fixedly mounted inside. A lead screw 6 is movably connected inside the stepper motor 5, which pushes the syringe 4 to inject liquid into the tubular reactor 3. A sampling bottle 7 is embedded inside the base 1. The top surface of the base 1 has a through hole that matches the sampling bottle 7, making it easy to place and remove the sampling bottle 7. The output end of the syringe 4 is connected to one end of the tubular reactor 3 through a liquid outlet pipe 8. The other end of the tubular reactor 3 is connected to a gas outlet pipe 9. A ball valve 11 is installed at the output end of the gas outlet pipe 9. The ball valve 11 is connected to the sampling bottle 7 through a collection pipe 10. The output end of the sampling bottle 7 is also connected to an exhaust pipe 12. A ball valve 2 13 is installed at the end of the exhaust pipe 12 away from the sampling bottle 7. The reaction gas enters the sampling bottle 7 through the ball valve 11, while the ball valve 2 13 is closed. After collecting enough gas, the ball valve 11 is closed, completing the hydrogen-rich gas collection.

[0021] Furthermore, a latch 14 is fixedly installed on the front of the tubular heater 2. The latch 14 is used to open and close the outer shell of the tubular heater 2. At the same time, the interior of the tubular heater 2 is provided with an installation groove that is compatible with the tubular reactor 3. The latch 14 facilitates the installation of the tubular reactor 3 into the interior of the tubular heater 2.

[0022] Furthermore, the interior of the tubular reactor 3 is filled with methanol reforming catalyst 16. The temperature is raised to the reaction temperature of the methanol reforming catalyst 16 by the tubular heater 2. The methanol aqueous solution is rapidly vaporized in the tubular reactor 3 and reformed by the catalyst to generate hydrogen and other gases.

[0023] Furthermore, the syringe 4 is filled with a 60% methanol aqueous solution.

[0024] In a further embodiment, a control panel 15 is also provided on the top of the base 1, and the liquid flow rate and the temperature of the tubular heater 2 are controlled by the knob of the control panel 15.

[0025] In a further embodiment, a temperature sensor is installed inside the tubular furnace 2. The temperature sensor collects the temperature of the tubular furnace 2 and controls the temperature of the tubular furnace 2 through feedback signals.

[0026] The specific working process of a teaching tool for demonstrating the principle of methanol reforming according to the above embodiments is described below: A tubular reactor 3 is filled with a methanol reforming catalyst 16, and the tubular reactor 3 is installed inside a tubular furnace 2. Simultaneously, a syringe 4 is filled with a 60% methanol aqueous solution. The syringe 4 is pushed by the lead screw 6 on the stepper motor 5 to inject liquid into the tubular reactor 3. The temperature of the tubular furnace 2 is raised to the reaction temperature of the methanol reforming catalyst 16. The methanol aqueous solution rapidly vaporizes inside the tubular reactor 3, and hydrogen and other gases are generated through catalyst reforming. During this process, a temperature sensor collects the temperature of the tubular furnace 2, and the temperature of the tubular furnace 2 is controlled by the feedback signal. The liquid flow rate and the temperature of the tubular furnace 2 are controlled by the knob on the control panel 15. The reaction gas enters the sampling bottle 7 through ball valve 11, while ball valve 2 13 is closed. After sufficient gas is collected, ball valve 11 is closed to complete the hydrogen-rich gas collection. After collection, the collected hydrogen-rich gas can also be released by opening ball valve 2 13 to facilitate subsequent related experiments.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
