Abstract
A combined reforming apparatus is provided. The combined reforming apparatus includes two or more catalyst tubes reacting at different temperatures, and allows different reforming reactions to be performed subsequently as the combustion gas supplies heat to two or more catalyst tubes one after another.
Claims21
A combined reforming apparatus comprising:
- a body;
- one or more first catalyst tubes disposed inside the body and configured to react at a first temperature;
- one or more second catalyst tubes disposed inside the body, connected to the first catalyst tube, and configured to react at a second temperature higher than the first temperature;
- and
- a combustion unit configured to supply heat to the first and second catalyst tubes,
- wherein a plurality of first catalyst tubes and a plurality of second catalyst tubes are provided, and
- wherein a plurality of combustion gas discharge units, through which the combustion gas supplied by the combustion unit is discharged after supplying heat to the plurality of the first catalyst tubes and the plurality of the second catalyst tubes, are spaced apart at a uniform interval along a circumferential direction of the body.
