A preparation method of Y-Ni/activated carbon catalysts capable of stably performing a supercritical water vaporization reaction of organic materials, and a system and a method for producing hydrogen by supercritical water vaporization of the organic materials using the Y-Ni/activated carbon catalysts are provided. A system for producing hydrogen by supercritical water vaporization of organic materials using a Y-Ni/activated carbon catalyst comprises: a reactor(20) including a reaction pipe(21) which is divided into a preheating part(21a) and a vaporization part(21b), a vaporization part thermocouple, a preheating part thermocouple(211), a plurality of thermocouples(23), a cylindrical heating furnace(22), a front heater(25a), a rear heater(25b), and a support(28); a first storage vessel(30a) and a second storage vessel(30b) which have digital balances(31a,31b) mounted on bottom sides thereof, and which are connected to a cross(34) communicating with a front end of the reactor by supply pipes(11), wherein high pressure pumps(32a,32b) and valves(33a,33b) are mounted on the supply pipes; a solid remover(40) installed on a discharge pipe(12) formed on a rear end of the reactor; a high pressure manometer(50) measuring pressure in the discharge pipe; a post-pressure controller(60) controlling the pressure in the discharge pipe; a gas-liquid separator(70) separating a product decompressed to the atmospheric pressure through the post-pressure controller into gas phase and liquid phase; a gas collecting part(80) collecting a gas sample from the product in the gas phase; and a gas flow meter(90) measuring flow rate of the produced gas in real-time. |
