Title:
HYDROGEN PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/029543
Kind Code:
A1
Abstract:
The present invention is a hydrogen production method in which a partial oxidation reaction and a steam reforming reaction of a hydrocarbon-type compound such as methanol are allowed to proceed to produce hydrogen, wherein the life of a catalyst can be prolonged and hydrogen can be produced steadily for a long period. A liquid raw material comprising methanol and water is vaporized in a raw material vaporizing section (1), a vaporized fluid gas and an oxygen-containing gaseous raw material are supplied to a reactor (2A), and a partial oxidation reaction and a steam reforming reaction (a decomposition reaction) of methanol proceed in the reactor (2A) to produce hydrogen. As a heat source for vaporizing the liquid raw material in the vaporizer (2A), combustion heat generated in a gas combustion section (9) can be used. The combustion heat generated in the gas combustion section (9) is generated by the combustion using, as a combustion gas, a detached gas that is detached from a hydrogen gas separation section (3) in multiple steps. In the hydrogen gas separation section (3), the detached gas is allowed to flow while altering the amount of outflow of the detached gas.
