SYSTEM FOR PRODUCING HYDROGEN FROM ORGANIC WASTE

摘要

PROBLEM TO BE SOLVED: To provide a system which can produce hydrogen from sludge because it is equipped with: a supercritical water reaction vessel for reacting supercritical water with an organic waste and then fixing carbon dioxide on calcium oxide (quick lime) by converting it to calcium carbonate to produce hydrogen or methane; and a circulatory fluid bed furnace for calcining the residual solid component left in the organic waste and containing the calcium carbonate separated from the supercritical water reaction vessel. SOLUTION: The supercritical water reaction vessel 4 reacts supercritical water with sludge, that is, an organic waste and then fixes carbon dioxide on calcium oxide (quick lime) by converting to calcium carbonate to produce hydrogen. The circulatory fluid bed furnace 8 calcines the residual solid component left in the organic waste and containing the calcium carbonate separated from the supercritical water reaction vessel 4 through a solid-liquid separator 5 to produce calcium oxide (quick lime) and then returns it back into the supercritical water reaction vessel 4 through a mixer 1.
