Catalytic hydrogen production method for quickly and continuously generating hydrogen by utilizing kitchen wastes

The invention discloses a catalytic hydrogen production method for quickly and continuously generating hydrogen by utilizing kitchen wastes. The catalytic hydrogen production method comprises the following steps: pre-treating collected kitchen wastes and removing inorganic solid wastes; replenishing the pretreated raw materials with water till water content is 90-95%, and adding 5wt% of catalyst;pumping into a supercritical water gasification reactor by a high pressure pump, preheating in a heat exchanger before entering into the reactor and heating to 500-550 DEG C in an electric heater; guiding total product acquired from 60-minute reaction in the supercritical reactor to flow by the heat exchanger, exchanging heat with raw materials, and passing by a reducing valve, a gas-liquid separator, a solid-liquid separator and a dryer in turn after heat exchange, thereby acquiring solid residue and high-value hydrogen-rich gas; taking a liquid product as replenishing water for cycle use. According to the invention,
