Abstract

The invention relates to a hydrogen separation and water gas reforming integrated high-pressure hydrogen production system. The system comprises a reformer, a three-phase heat exchange device, a steamtrap, a water-cooled heat exchanger, a carbon dioxide liquefaction device and a hydrogen separation and water gas reforming integrated device; and the pump pressure of a liquid pump is 18-50 Mpa, andthe operating temperature of the water-cooled heat exchanger is 18-30.8 DEG C. A high-pressure hydrogen production method comprises the following steps: methanol-water steam undergoes a reforming reaction in the reformer to generate a mixed gas of hydrogen, carbon dioxide and carbon monoxide, the obtained hydrogen mixed residual gas is fed into the water gas reforming cavity of the water gas reforming integrated device, and water is distributed to prepare a reformed mixed gas; and the reformed mixed gas enters a hydrogen separation cavity and is mixed with the mixed gas of hydrogen, carbon dioxide and carbon monoxide, and the finally obtained mixed gas is subjected to hydrogen separation operation in the hydrogen separation cavity. The gas in the system is circularly purified, the theoretical yield can reach 100%, and the hydrogen yield is greater than or equal to 95%.

Description

technical field [0001] The invention relates to a hydrogen separation and water gas reforming integrated high-pressure hydrogen system and a method thereof. Background technique [0002] Hydrogen energy is the most ideal energy source in the 21st century. As a fuel for automobiles, it is easy to start at low temperature, and has little corrosion effect on the engine, which can prolong the service life of the engine. Because hydrogen and air can be mixed evenly, the carburetor used in general cars can be completely omitted, thereby simplifying the structure of existing cars. Even more interesting, just add 4% hydrogen to gasoline. Using it as a vehicle engine fuel can save fuel by 40%, and there is no need to make much improvement to the gasoline engine. Hydrogen fuel cell as power generation system. [0003] No pollution, the fuel cell has no pollution to the environment. It uses electrochemical reaction instead of combustion (gasoline, diesel) or energy storage (battery...
