NOVELTY - The hydrogen production system has melting reformer (4), slag recovery equipment (6), quick cooling tower (7), gas purification apparatus (9), decarboxylation apparatus (10), and hydrogen recovery unit (11). Reformer (4) generates reformed gas by carrying out heat processing of thermal decomposition gas obtained by melting dried and degassed garbage. Apparatus (10) removes carbon dioxide from reformed gas ejected from apparatus (9).    USE - For producing hydrogen.    ADVANTAGE - The system economically enables the production of hydrogen, and utilization efficiency of thermal decomposition gas produced from garbage melting reformer is improved.    DETAILED DESCRIPTION - The hydrogen production system has garbage melting reformer (4), a slag recovery equipment (6), a quick cooling tower (7), a gas purification apparatus (9), a decarboxylation apparatus (10) and a hydrogen recovery unit (11). The reformer (4) generates reformed gas by carrying out heat processing of thermal decomposition gas at high temperature. The thermal decomposition gas is obtained by melting drying-degassing processed garbage at high temperature. The equipment (6) recovers the slag from reformer (4) after melting. The tower (7) carries out rapid cooling of reformed gas ejected from reformer. The apparatus (9) removes impurity from reformed gas ejected from tower (7). The apparatus (10) removes carbon dioxide from reformed gas ejected from apparatus (9). The unit (11) separates and purifies hydrogen from decarbonated gas ejected from apparatus (10). The decarbonated gas is supplied as supplementary fuel to slag extraction location of reformer (4).    DESCRIPTION OF DRAWING(S) - The figure shows the flowchart of hydrogen production system.
