NOVELTY - A hydrogen separation type hydrogen production system comprises hydrogen separation type steam reforming device (A) by steam reforming of hydrocarbon fuel, combustor (B) which is heat sources for steam reforming of hydrocarbon fuel, and boiler (C) for water vapor generation of hydrocarbon fuel for modification.    USE - A hydrogen separation type hydrogen production system.    ADVANTAGE - The hydrogen production system remarkably reduces environmental impact.    DETAILED DESCRIPTION - A hydrogen separation type hydrogen production system comprises hydrogen separation type steam reforming device (A) by steam reforming of hydrocarbon fuel, combustor (B) which is heat sources for steam reforming of hydrocarbon fuel, and boiler (C) for water vapor generation of hydrocarbon fuel for modification. The hydrogen separation type hydrogen production system utilizes oxygen-burning technic for combustor by oxygen or oxygen rich gas including introducing combustor into water separator (D), merging combustion exhaust gas from combustor and combustion exhaust gas from boiler after cooling off gas from hydrogen separation type steam reforming device, separating into moisture content and gas in merging gas in water separator, recycling drained water separated with water separator as water for source gas modification in hydrogen separation type steam reforming device, introducing gas separated with water separator into gas-liquid separation tank (F) through moisture-content adsorber, compressor and cooling-heat heat exchanger one by one, and separating into liquid dioxycarbon and carbon-dioxide separation completed off gas, and utilizing carbon dioxide as fuel in combustor while collecting separated liquid dioxycarbons.
