Abstract

An apparatus for steam reforming of hydrocarbons, the apparatus comprising a vessel defining a combustion chamber. The combustion chamber has a burner device for combustion of a fuel and a flue gas outlet for exhausting flue gas resulting from the combustion. A second chamber is integrally formed with the vessel. The second chamber comprises a first inlet conduit adapted for receiving water therein and an outlet conduit for exhausting steam. A reformer tube in the combustion chamber is filled with a catalyst and is connected to a second inlet conduit for having a steam and hydrocarbon mixture flow therethrough, and to a second outlet conduit for exhausting a process gas resulting from a steam reforming process in the reformer tube. The reformer tube is disposed in the combustion chamber so as to transfer heat from the combustion to the steam reforming process. Flue gas from the combustion chamber and process gas from the reformer tube are used for transferring heat to the water in the second chamber so as to produce steam to be used for the steam reforming process.
