Abstract:
In the invention, a reaction tube comprises at least one first reaction tube and at least one second reaction tube. The first reaction tube comprises: a multi-layered structure tube that is formed from a cylindrical non-porous layer and a cylindrical porous layer stacked on the inner side of the non-porous layer, has a fluid inlet and a fluid outlet, and has a reaction tube inner cavity connecting the fluid inlet with the fluid outlet; and a catalyst supported by the porous layer. The second reaction tube comprises: a single layer structure tube that is formed from a cylindrical non-porous layer, has a fluid inlet and a fluid outlet, and has a reaction tube inner cavity connecting the fluid inlet with the fluid outlet; and a catalyst filling the reaction tube inner cavity of the single layer structure tube. The fluid outlet of the first reaction tube is connected to the fluid inlet of the second reaction tube such that the reaction tube inner cavities of the first reaction tube and the second reaction tube communicate with each other.
