Combined reforming apparatus

Abstract

A combined reforming apparatus is provided. The combined reforming apparatus includes a body, a first catalyst tube disposed inside the body and reacting at a first temperature to reform hydrocarbons (CxHy) having two or more carbon atoms into methane (CH4), a second catalyst tube disposed inside the body, connected to the first catalyst tube, and reacting at a second temperature higher than the first temperature to reform methane (CH4) into synthesis gas comprising hydrogen (H2) and carbon monoxide (CO), a combustion unit configured to supply heat to the first and second catalyst tubes, a gas supply pipe configured to supply hydrocarbon gas to the first catalyst tube, a first steam supply pipe configured to supply steam to the first catalyst tube, and a second steam supply pipe configured to supply steam to the second catalyst tube.
