Embodiment 1

[0082] see figure 1, the present invention discloses a high-efficiency methanol water hydrogen production system, the system includes: a liquid storage container 10, a heat exchanger 21, a gasification chamber 22, a reforming chamber 23, and a separation chamber 24. The liquid storage container 10, the heat exchanger 21, the vaporization chamber 22, the reforming chamber 23, and the separation chamber 24 are connected in sequence through pipelines.

[0083] The separation chamber 24 is provided with a ceramic membrane separator 241 and a metal palladium membrane separator 242, and the gas entering the separation chamber 24 is pretreated through the ceramic membrane separator 241 to obtain higher-purity hydrogen; the higher-purity hydrogen Then enter the metal palladium membrane separator 242 to obtain hydrogen with higher purity.

[0084] Of course, the separation chamber can also be provided with a plurality of ceramic membrane separators and a plurality of metal palladium m...

Embodiment 2

[0094] see image 3 , the present invention discloses a high-efficiency methanol water hydrogen production system, the system includes: a liquid storage container 10, a main hydrogen production equipment 20, and one or more sub-hydrogen production equipment 30. The hydrogen or / and residual gas produced by one or more sub-hydrogen production equipment 30 is finally used as the initial start-up energy of the main hydrogen production equipment 20 . When part of the hydrogen or / and residual gas produced by the sub-hydrogen production equipment 30 meets the set amount, the main hydrogen production equipment 20 is started; thereafter, the hydrogen or / and residual gas produced by the main hydrogen production equipment 20 maintains the main hydrogen production equipment 20 runs.

[0095] As mentioned above, the hydrogen production system can have one or more sub-hydrogen production equipment 30. In the case where the system includes multiple sub-hydrogen production equipment 30, each...

Abstract

The invention reveals a high efficiency methanol-water hydrogen production system and a hydrogen production method thereof. The system comprises a liquid reservoir vessel, a heat exchanger, a vaporizer, a reforming chamber and a separation chamber, wherein the liquid reservoir vessel, the heat exchanger, the vaporizer, the reforming chamber and the separation chamber are successively connected through pipelines, a ceramic membrane separator and a metallic palladium membrane separator are arranged in the separation chamber, gas entering into the separation chamber is pretreated by the ceramic membrane separator to obtain high purity hydrogen, and then the high purity hydrogen enters into the metallic palladium membrane separator so as to obtain hydrogen with higher purity. According to the high efficiency methanol-water hydrogen production system and the hydrogen production method thereof, the high purity hydrogen (with a purity of about 99%) is separated from reformed gas through the ceramic membrane separator at first, and then the hydrogen with higher purity (more than 99.9999%) is separated through the metallic palladium membrane separator.

Description

technical field [0001] The invention belongs to the technical field of hydrogen preparation, and relates to a hydrogen production system, in particular to an efficient methanol water hydrogen production system; meanwhile, the invention also relates to an efficient methanol water hydrogen production method. 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, which can continu...
