Abstract (en)
[origin: WO2008009250A1] The invention relates to a reformer for reacting fuel and oxidant to gaseous reformate. Said reformer comprises an oxidation zone (10), an evaporation zone (16), and a catalytic H<SUB>2</SUB> production zone (20). A gaseous mixture of fuel and oxidant can be fed to the oxidation zone (10) for oxidation purposes, a process during which oxidant-containing exhaust gas is produced; fuel and an evaporator gas can be fed to the evaporation zone (16) so as to produce a fuel-containing evaporator gas mixture; and an ignitable reforming gas mixture containing evaporated fuel and oxidant-containing exhaust gas can be fed to the catalytic H<SUB>2</SUB> production zone (20) so as to produce the gaseous reformate. In order to reduce the risk of spontaneous ignition in the evaporator zone (16), mixing and feeding means (28) to which oxidant-containing exhaust gas can be fed from the oxidation zone (10) and fuel-containing evaporator gas mixture can be fed from the evaporation zone (16) are disposed upstream of an inlet of the catalytic H<SUB>2</SUB> production zone (20) so as to produce the reforming gas mixture and feed said reforming gas mixture into the catalytic H<SUB>2</SUB> production zone (20). Recirculation means (26) are provided for recirculating reformate produced in the catalytic H<SUB>2</SUB> production zone (20) into the evaporation zone (16) as evaporator gas. The inventive design prevents an ignitable gas mixture from forming in the evaporator zone (16). The invention further relates to a corresponding method for reacting fuel and oxidant to gaseous reformate.
