HYDROGEN GAS PRODUCING APPARATUS AND HYDROGEN GAS PRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen gas producing apparatus and a hydrogen gas producing method that are applied to excrement of humans and animals and organic waste and can produce hydrogen gas while reducing contaminants generated from the organic waste and the like.SOLUTION: A hydrogen gas producing apparatus includes a tank that can be filled with high pressure water. The high pressure water is heated to a high temperature in a heat exchanger and then mixed with organic waste and the like under agitation. A mixture of the organic waste and the like and water is pressurized in an agitation vessel with a high pressure pump. The high pressure mixture of the organic waste and the like and water flows through a static mixer at a high pressure and high temperature to reach a supercritical state. The mixture of the organic waste and the like and water in a supercritical state is then separated into hydrogen gas and impurities when passing through a liquid cyclone.
