Autothermer Reformierungsreaktor

WO 200124922 A UPAB: 20010603 NOVELTY - An autothermal reforming reactor comprises an endothermic reaction zone for the reforming reaction; an exothermic reaction zone, in which energy for the reforming reaction is released; and a quenching zone connected to the reaction zones for quench cooling the reactor gas stream by adding a liquid. DETAILED DESCRIPTION - Autothermal reforming reactor comprises an endothermic reaction zone for the reforming reaction; an exothermic reaction zone, in which energy for the reforming reaction is released; and a quenching zone connected to the reaction zones for quench cooling the reactor gas stream by adding a liquid. The endothermic reaction zone and the quench zone are separated by a gas permeable heat shield (HS) comprising a thermal insulation (IS) for insulating the endothermic reaction zone and the quench zone, and a temperature radiator (STR) which faces the endothermic reaction zone to radiate thermal energy absorbed by the reactor gas stream in a counter current flow. Preferred Features: The heat shield consists of a vaporizer structure (VD) made of metal foam on a side facing the quenching zone. The exothermic reaction zone is connected to the endothermic reaction zone. The heat shield has flow channels (GK) whose walls are formed by the temperature radiator. The radiator is made of metal, ceramic or a metal-ceramic composite. The thermal insulation is made of ceramic. USE - For operating fuel cells having polymer membranes by reforming liquid hydrocarbons such as gasoline or diesel. ADVANTAGE - Temperature distribution is optimized
