Abstract (en)
[origin: WO2004046026A1] The invention concerns a method and a device for producing fuel gases containing hydrogen for electrochemical cells, said method consisting in catalytic reforming of hydrocarbons and subsequent purifying of the gas. The method is characterized in that the catalytic reforming is carried out in two successive steps, the first operation being an autothermal reforming process and the second operation consisting in a low-temperature vapour reforming process, at temperatures lower than 650 DEG C. In the first step (autothermal reforming process), a mixture of starting products consisting of hydrocarbons, oxygen and water or water vapour is partly transformed into a gas mixture rich in hydrogen by means of a catalyst during an autothermal reforming process. Said mixture, which still contains hydrocarbon residues, is then transformed into a fuel gas rich in hydrogen during the subsequent vapour reforming process (second step). Thus a fuel gas containing a very high part of hydrogen and exiting the reactor at a temperature between 400 and 650 DEG C is obtained. Said exhaust temperatures being low, the fuel gas can be directly subjected to the purifying step, without requiring the use of additional heat exchangers. Additionally to the increased reforming performance, the invention also enables a more compact and less costly reformer design. Said method and said device are useful for generating hydrogen or fuel gases containing hydrogen for electrochemical cells, in particular for mobile or fixed applications.
