Abstract

The invention relates to a methanol-water steam and hydrogen mixed gas integrated high-pressure hydrogen production system. The system comprises a three-phase heat exchange device, a reforming device,a hydrogen separation device, a steam trap, a water-cooled heat exchanger, a refrigerating machine and a carbon dioxide liquefaction device; and the pump pressure of a liquid pump is 18-50 MPa. A high-pressure hydrogen production method comprises the following steps: methanol-water steam is subjected to a reforming reaction in an upper reaction cavity to generate a mixed gas of hydrogen, carbon dioxide and carbon monoxide, hydrogen separation is carried out, and the obtained carbon dioxide mixed residual gas undergoes carbon dioxide liquefaction separation to prepare liquid carbon dioxide anda hydrogen mixed residual gas in a carbon dioxide separator, wherein the hydrogen mixed residual gas is close to the hydrogen, carbon dioxide and carbon monoxide mixed gas in hydrogen, carbon dioxideand carbon monoxide proportions; and the hydrogen mixed residual gas and the hydrogen, carbon dioxide and carbon monoxide mixed gas enter a hydrogen separation cavity together and undergo hydrogen separation operation. The hydrogen production efficiency of the hydrogen production system is improved, and the structure of the whole hydrogen production system is optimized and simplified, so the hydrogen production system can be processed to form a small hydrogen production apparatus.

Description

technical field [0001] The invention relates to an 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) - the most typical traditional backup pow...
