Abstract

The invention relates to an ultrahigh-pressure hydrogen production system integrating methanol water vapor and hydrogen mixed gas. The system includes a three-phase heat exchange device, a reformer, ahydrogen separation device, a steam trap, a water-cooled heat exchanger, a refrigerator, and a carbon dioxide liquefaction device, wherein the pump pressure of a liquid pump is 40 to 100 MPa, the operating temperature of the water-cooled heat exchanger is not more than 30.8 DEG C, and pure hydrogen is pumped into a hydrogen storage tank under the pump pressure of the liquid pump. An ultrahigh-pressure hydrogen production method includes subjecting methanol water vapor to a reforming reaction to generate a mixed gas of hydrogen, carbon dioxide and carbon monoxide; then performing hydrogen separation; preparing, in a carbon dioxide separator, liquid carbon dioxide and residual hydrogen mixed gas having a hydrogen-carbon dioxide-carbon monoxide ratio close to that in the mixed gas of hydrogen, carbon dioxide and carbon monoxide; feeding the mixed gas together into a hydrogen separation chamber for hydrogen separation. The hydrogen production efficiency of the hydrogen production system is improved, so that the hydrogen production system can be made into small hydrogen production equipment.

Description

technical field [0001] The invention relates to an integrated ultra-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 back...
