Hydrocarbons and steam, which are raw material gases, are preheated to about 450°C, for example, and then introduced into the outer tube 2 through the introduction tube 5, and are then introduced into the catalyst layer 7 formed between the outer tube 2 and the inner tube 6. contact with the catalyst 3 of. Here, the raw material gas undergoes a steam reforming reaction and becomes a mixed gas (reformed gas) of H 2 , CO, CO 2 and the like. The steam reforming reaction is an endothermic reaction, and in order to compensate for this amount of heat, the outside of the outer tube 2 is heated by combustion gas. Further, in the steam reforming reaction, the hydrogen gas component increases as the temperature increases, so in a typical hydrogen production plant, the reformed gas temperature (reaction temperature) at the outlet of the catalyst bed 7 is set at, for example, about 800°C. Combustion gas heating is also used to increase this reformed gas temperature. After the reaction, the high-temperature reformed gas passes through a plurality of small holes (not shown) in the receiving tray 8, reverses its flow at the end cap 4, passes through the inner tube 6, and exits at the outlet tube 9 while remaining at a high temperature.
From there, it is led out of the reaction tube 1, that is, out of the system.

The conventional reactor is configured as described above, and in order to improve the heat transfer coefficient between the reformed gas in the inner layer 6 and the wall of the inner tube 6, the inner tube 6 has a small diameter and the flow rate of the reformed gas is reduced. As the temperature increases, the heat transfer area decreases,
Conversely, when the heat transfer area is increased, the flow rate of the reformed gas in the inner tube 6 is reduced, and the heat transfer coefficient is reduced. Therefore,
The reformed gas at about 800℃ in the 4th part of the end cap is
There was a problem that there was a waste of heat as it was discharged out of the system while still being at a high temperature.

Hydrocarbons and steam, which are raw material gases, are preheated to about 450°C, for example, and then introduced into the outer tube 2 from the introduction tube 5 as in the conventional case, and come into contact with the catalyst 3 in the catalyst layer 7, where they undergo steam reforming. produce a reaction. After the reaction, the high-temperature reformed gas passes through a plurality of small holes (not shown) in the receiving tray 8, reverses its flow at the end cap 4, and passes through the inner peripheral space of the heat pipe 10 to the outlet pipe. 9 is discharged from the system. By the way, the high temperature reformed gas that has passed through the catalyst layer 7 comes into thermal contact with the heat absorption section 10a of the heat pipe 10, and the sensible heat of the high temperature reformed gas is absorbed by the heat absorption section 10a of the heat pipe 10. That is, the heat absorbing portion 10a of the heat pipe 10 is heated, and this heating also heats the working liquid 14 sealed inside the hollow groove 13 of each heat pipe 10, absorbing the sensible heat of the high-temperature reformed gas as latent heat of vaporization and converting it into steam. and moves inside the hollow groove 13 to the heat dissipation part 10b of the heat pipe 10. Heat radiation part 10b of heat pipe 10

Heat is radiated into the raw material gas introduced into the catalyst layer 7 via the catalyst holding pipe 15 to compensate for the temperature rise of the raw material gas or reformed gas or the heat of reaction. At this time, the vapor of the working liquid 14 is condensed and liquefied. The condensed and liquefied working liquid 14 moves inside the hollow groove 13 and returns to the heat absorption section 10a of the heat pipe 10.
In this way, by repeatedly vaporizing and liquefying the working liquid 14 in the heat pipe 10, the catalyst layer 7
The sensible heat of the high temperature reformed gas passing through the heat pipe 1

It is also possible to obtain effective reaction characteristics. After being effectively used, the reformed gas is stored in the inner circumferential space of the heat pipe 10,
It is discharged to the outside of the system through the outlet pipe 9. This makes it possible to downsize the device and reduce auxiliary fuel costs.
