Embodiment 1
[0051] see figure 1 , the present invention discloses a hydrogen production equipment, the equipment includes: a liquid storage container 2, a heat exchanger 4, a gasification chamber 5, a reforming chamber 6, a separation chamber 7; the liquid storage container 2, a heat exchanger 4. The gasification chamber 5, the reforming chamber 6, and the separation chamber 7 are connected in sequence through pipelines.
[0052] The methanol and water in the liquid storage container 2 are transported to the heat exchanger 4 through the delivery device 3 for heat exchange, and after the heat exchange 4, enter the gasification chamber 5 for gasification; the vaporized methanol vapor and water vapor enter the reforming chamber 6 , A catalyst is provided in the reforming chamber 6, and the temperature in the reforming chamber 6 is 280°C-409°C. In one embodiment of the present invention, the temperature in the reforming chamber 6 is 370°C-400°C, for example, the temperature in the reforming ...

The invention discloses a hydrogen preparation method and a hydrogen preparation device. The method comprises enabling methyl alcohol and water to be delivered to a heat exchanger for heat exchange through a delivery device and to enter a vaporizing chamber for vaporizing after heat exchange; enabling methyl alcohol steam and steam after vaporizing to enter in a reforming chamber provided with a catalytic agent inside, enabling the temperature in the reforming chamber to be 280-409 DEG C; enabling a transfer passage between the reforming chamber and a separation chamber to pass through a preheat temperature control mechanism which is used for heating gas output from the reforming chamber and serves as buffer between the reforming chamber and the separation chamber to enable the temperature of the gas output from the reforming chamber to be same with or close to the temperature of the separation chamber; enabling the temperature in the separation chamber to be set to be 400-460 DEG C, enabling a film separator to be arranged in the separation chamber, and obtaining hydrogen from a gas generation end of the film separator. The preheat temperature control mechanism is arranged on a pipeline between the reforming chamber and the separation chamber, low temperature requirements of the catalytic agent in the reforming chamber can be respectively guaranteed, high temperature requirements in the separation chamber are met, and hydrogen preparation efficiency is improved accordingly.
Description
technical field [0001] The invention belongs to the technical field of hydrogen preparation, and relates to a method for preparing hydrogen, in particular to a method for preparing hydrogen by using methanol and water; meanwhile, the invention also relates to a device for preparing hydrogen by using methanol and water. Background technique [0002] Among the many new energy sources, hydrogen energy will become the most ideal energy source in the 21st century. This is because, in the case of burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water, without ash and waste gas, and will not pollute the environment; while the combustion of coal and oil produces These are carbon dioxide and sulfur dioxide, which produce the greenhouse effect and acid rain, respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, whic...
