PROBLEM TO BE SOLVED: To provide a method of manufacturing hydrogen, in which hydrogen is generated by modifying a pyrolysis gas generated when pyrolyzing a carbonaceous raw material under the presence of a catalyst, an adverse effect on an operation due to carbon deposition generated on a surface of the catalyst is prevented, and the catalyst is made reusable.SOLUTION: An apparatus of manufacturing hydrogen from a carbonaceous raw material 1, in which a heat transport medium is used by repeatedly circulating by moving in an order of a combustion/regenerator 10, a modifier 8, a pyrolyzing device 7, and a transport device 9, the heat transport medium is made of a catalyst solid matter 6, the pyrolizing device 7 pyrolyzes the carbonaceous raw material 1 by using sensible heat of the catalyst solid matter 6, a generated pyrolysis gas is discharged to the modifier 8 and generated char 3 and the catalyst solid matter 6 are discharged to the transport device 9, the modifier 8 makes a modifying agent 4 react with a pyrolysis gas 2 of which temperature is elevated by the sensible heat of the catalyst solid matter 6 to produce a hydrogen-containing gas 5, the char 3 transported by the transport device 9 and the catalyst solid matter 6 are burned in the combustion/regenerator 10, and the modifying agent 4 is indirectly heated by the sensible heat of a combustion waste gas 13 at a heat exchanger 14.SELECTED DRAWING: Figure 1 【課題】炭素質原料を熱分解した際に発生する熱分解ガスを、触媒存在下で改質して水素を製造すると共に、触媒表面で生じる炭素析出による操業への悪影響を防止し、更に、触媒を再利用可能とする。【解決手段】熱輸送媒体を、燃焼／再生器１０、改質器８、熱分解器７、搬送装置９の順に、移動させて繰り返し循環使用する炭素質原料１から水素を製造する装置であって、熱輸送媒体は、触媒固形物６からなり、熱分解器７は、炭素質原料１を触媒固形物６の顕熱を用いて熱分解し、生成した熱分解ガスを改質器８へと排出すると共に、生成したチャー３と触媒固形物６とを搬送装置９へと排出し、改質器８は、触媒固形物６の顕熱を用いて温度上昇した熱分解ガス２に改質剤４を反応させて水素含有ガス５を製造し、搬送装置９で移送されたチャー３と触媒固形物６とを、燃焼／再生器１０により燃焼させ、熱交換器１４にて燃焼排ガス１３の顕熱で改質剤４を間接加熱する。【選択図】図１
