<p><P>PROBLEM TO BE SOLVED: To provide a reforming apparatus and its operation method capable of uniformly mixing water(steam) and a raw material, preventing the deposition of carbon without using a temperature controller, and effectively heating water and the mixture by a heating gas. <P>SOLUTION: The reforming apparatus is equipped with a first evaporator 05 which is cylindrical and has a first flow path, a second evaporator 06 which is cylindrical and has a second flow path, a piping 027 which connects the first flow path outlet and the second flow path inlet, and a raw material mixing part 028 which is installed halfway in the piping. The first evaporator and the second evaporator are concentrically arranged and the space between the first evaporator and the second evaporator becomes a heating gas flow path 024. At the first evaporator, water 021 passing through the first flow path is heated by a heating gas to be converted to steam and a raw material is mixed into the steam at the raw material mixing part to form a mixture. At the second evaporator, the mixture passing through the second flow path is heated by a heating gas to be converted to a superheated steam and then the superheated steam is passed through a reforming catalyst layer 03. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
