Abstract

The invention relates to an autothermic reforming reactor, comprising an endothermic reaction zone, in which the reforming reaction takes place; an exothermic reaction zone, in which the energy is released which is required for the reforming reaction; a quench zone connected downstream of the reaction zones for the rapid cooling of the reactor gas volume flow. According to the invention, the endothermic reaction zone and the quench zone are separated by a gas permeable heat shield (HS), whereby the heat shield (HS) comprises thermal insulation (IS) for thermally insulating the endothermic reaction zone and quench zone, in addition to a thermal radiator (STR) which faces the endothermic reaction zone and radiates the thermal energy which has been absorbed from the reactor gas volume flow.
