The inventive apparatus for the execution of endothermic reactions between gaseous reactants at heightened temperature and increased pressure encompasses the following main components: an inner isolating hull (33) for conveying the feed substances from their inlet (E) along the clearance between the pressure wall (31) of the apparatus and said hull; a tube-bundle heat exchanger (39'), placed within said hull for the internal heat recovery, whereby the feed substances are outside of the tubes (39) of said heat exchanger; a catalyst material, disposed in the lower part of said heat exchanger and/or after it in flowing direction; heating means (37, 37'') arranged within said catalyst material for the supply of heat energy to the reactants at the region of the final conversion, whereby the reaction products proceed inside of the said tubes, with heat delivery to the entering feed substances to the outlet of the apparatus. All said parts are arranged within a pressure vessel (31). Processes for producing a hydrogen-rich gas may be carried out by using an apparatus as indicated. For that the necessary amount of feed substances in form of steam and hydrocarbons and the necessary heat-energy in form of electrical energy and/or oxygen-containing gas for the partial oxidation of the reducing components in the feed substances are fed into said apparatus and the hydrogen-rich reaction products are withdrawn therefrom. Such processes are useful for the production of the feed stock to be used in the NH3- and/or CH3OH-synthesis. |
