A method for concentrating an aqueous hydrogen halide starting solution, in particular hydrochloric acid, includes the steps of extractive distillation of the aqueous hydrogen halide starting solution in the presence of an extraction agent in a distillation device, removing hydrogen halide vapor and/or hydrogen halide gas from the upper portion of the distillation device, removing an extraction-agent-containing solution from the lower portion of the distillation device, concentrating the extraction-agent-containing solution which is removed from the lower portion of the distillation device in an evaporation device, and returning the extraction-agent-containing solution which is concentrated in the evaporation device to the distillation device, wherein the extraction-agent-containing solution removed from the lower portion of the distillation device is concentrated in the evaporation device by evaporation at a pressure which is greater than atmospheric pressure.

A device for burning a fuel/oxidant mixture in a strongly exothermic reaction, consists of a reactor with a combustion chamber containing at least one first porous material and at least one second porous material in separate zones A and C. The zones are designed in such a way that an exothermic reaction can only occur in zone B, and with one or more feed lines for the fuel and for the oxidant, whereby zone A, which consists of the first porous material, is separated by a distance of approximately 10 mm to 4000 mm, for example approximately 20 mm to 500 mm, equating to one zone B, from zone C which consists of the second porous material and is located before zone C in a flow direction of the fuel/oxidant mixture.

A process is described for generating hydrogen through the oxidation of fuels that contain chemically bound hydrogen, in particular hydrocarbons, having the following process steps: a) introducing the fuel () as well as the oxidation agent () into a reactor () having a porous material () that is embodied in such a way that flame propagation in a direction opposite the direction of flow is prevented, and b) reacting the fuel with the oxidation agent in partial oxidation so that hydrogen is obtained in gaseous form. In addition, an apparatus for generating hydrogen that has a reactor that contains a porous material (), and the reactor () is embodied as a tubular reactor that has a central chamber () to introduce the fuel and the oxidation agent that extends in the axial direction and is delimited radially toward the outside by a first wall that has porous material (), and the first wall is delimited radially toward the outside by a second wall that contains the porous material (). Also described is an apparatus to generate hydrogen that has a reactor that contains a porous material and is characterized by the fact that its porosity in the direction of flame generation changes so that the pores are larger, that the porous material is disposed in a first zone and a second zone, which zones are adjacent to each other, and that a zone that has a porous material follows the one zone, seen in the direction of flow.
