PROBLEM TO BE SOLVED: To provide a desulfurization system, reforming system, fuel cell system and desulfurized raw-material production process in which the supply state of a hydrogen-containing gas to be mixed into a hydrodesulfurization target raw-material is suitably detected.SOLUTION: Provided is a desulfurization system 10 including a desulfurization unit 11 for hydrodesulfurizing a raw-material Dr, a hydrogen-containing gas supply unit 30 for mixing a hydrogen-containing gas R into the raw-material Dr, a raw-material supply unit 20 for supplying a mixed fluid DR of the raw-material Dr and the hydrogen-containing gas R into the desulfurization unit 11, and a state detection unit 16, and in which the raw-material supply unit 20 includes an un-desulfurized raw-material flow rate control unit 22 for controlling the flow rate of the mixed fluid DR in order to set the flow rate of the raw-material Dr supplied to the desulfurization unit 11 at a predetermined flow rate, and the state detection unit 16 detects the supply state of the hydrogen-containing gas R by comparing the output from the un-desulfurized raw-material flow rate control unit 22 that varies depending on the flow rate of the mixed fluid DR, with a reference value in a memory unit 18. Also provided are: a reforming system 50 including the desulfurization system 10 and a reforming unit 51; and a fuel cell system 1 including the reforming system 50 and a fuel cell 61.SELECTED DRAWING: Figure 1 |
