PROBLEM TO BE SOLVED: To provide a pyrolysis apparatus which is constituted so that a solid product is withdrawn from a tube while continuing progress of a pyrolysis process.SOLUTION: The pyrolysis apparatus for pyrolyzing a raw material fluid into the solid product and a fluid product includes: a reaction tube 130, which is used for circulating the raw material fluid to promote pyrolysis thereof and which has a first passage part 132, that is formed at one end side in the tube axial direction, and a second passage part 134 formed at the other end side so that the diameter of the first passage part becomes smaller than that of the second passage part and the flow passage cross sectional area of which is made larger gradually as it goes toward the second passage part from the first passage part; an adhesive force decreasing means for decreasing the adhesive force between the solid product, which is produced in the reaction tube by promotion of pyrolysis, and the inside wall of the reaction tube; and a moving means for moving the solid product, which is stuck to the inside wall of the reaction tube and the adhesive force of which is decreased by the adhesive force decreasing means, toward the second passage part side in the tube axial direction.SELECTED DRAWING: Figure 2 |
