An apparatus contains at least one pressure-rated apparatus shell and at least one modular framework system containing ceramic fiber composite materials and arranged within the apparatus shell. A modular lining apparatus includes the modular framework system and refractory bricks. The apparatus can be used for high-temperature reactors, especially electrically heated high-temperature reactors.

Device comprising a pressure-bearing device shell and an interior scaffolding system

The present invention relates to an electrically heatable packed pressure-bearing apparatus for conducting endothermic reactions having an upper (), middle () and lower () apparatus section, where at least one pair of electrodes () in a vertical arrangement is installed in the middle section () and all electrodes are disposed in an electrically conductive solid-state packing (), the upper and lower apparatus sections have a specific conductivity of 105 S/m to 108 S/m, and the middle apparatus section is electrically insulated against the solid-state packing, wherein the upper and lower apparatus sections are electrically insulated from the middle apparatus section, the upper electrode is connected via the upper apparatus section and the lower electrodes via the lower apparatus section or the electrodes are each connected via one or more connecting elements () that are in electrical contact with these sections and the ratio of the cross-sectional areas of the upper and lower electrode to the cross-sectional area of the respective current-conducting connecting element or, without use of a connecting element, the ratio of the cross-sectional area of the upper and lower electrode to the cross-sectional area of the respective current-conducting apparatus section is 0.1 to 10.

Solids-packed apparatus for performance of endothermic reactions with direct electrical heating

The present invention relates to a process for conducting endothermic gas phase or gas-solid reactions, wherein the endothermic reaction is conducted in a production phase in a first reactor zone, the production zone, which is at least partly filled with solid particles, where the solid particles are in the form of a fixed bed, of a moving bed and in sections/or in the form of a fluidized bed, and the product-containing gas stream is drawn off from the production zone in the region of the highest temperature level plus/minus 200 K and the product-containing gas stream is guided through a second reactor zone, the heat recycling zone, which at least partly comprises a fixed bed, where the heat from the product-containing gas stream is stored in the fixed bed, and, in the subsequent purge step, a purge gas is guided through the production zone and the heat recycling zone in the same flow direction, and, in a heating zone disposed between the production zone and the heat recycling zone, the heat required for the endothermic reaction is introduced into the product-containing gas stream and into the purge stream or into the purge stream, and then, in a regeneration phase, a gas is passed through the two reactor zones in the reverse flow direction and the production zone is heated up; the present invention further relates to a structured reactor comprising three zones, a production zone containing solid particles, a heating zone and a heat recycling zone containing a fixed bed, wherein the solid particles and the fixed bed consist of different materials.

Method and device for carrying out endothermic gas phase-solid or gas-solid reactions

The invention relates to a process for the parallel preparation of hydrogen, carbon monoxide and a carbon-comprising product, wherein one or more hydrocarbons are thermally decomposed and at least part of the pyrolysis gas formed is taken off from the reaction zone of the decomposition reactor at a temperature of from 800 to 1400&#xb0; C. and reacted with carbon dioxide to form a gas mixture comprising carbon monoxide and hydrogen (synthesis gas).
