  • Device comprising a pressure-bearing device shell and an interior scaffolding system
    Patent number: 11904290
    Abstract: 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.

  • Solids-packed apparatus for performance of endothermic reactions with direct electrical heating
    Patent number: 11882629
    Abstract: The present invention relates to an electrically heatable packed pressure-bearing apparatus for conducting endothermic reactions having an upper (3), middle (1) and lower (3) apparatus section, where at least one pair of electrodes (4, 5) in a vertical arrangement is installed in the middle section (1) and all electrodes are disposed in an electrically conductive solid-state packing (26), 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 (10, 16) that are in electrical contact with these sections and the ratio of the cross-sectional areas of the upper and lower electrode to the cr

  • Method for operating a descending moving bed reactor with flowable granular material
    Publication number: 20220387954
    Abstract: A method can be used for operating a descending moving bed reactor with flowable granular material. The method involves: (i) filling an upper lock-hopper with granular material and/or emptying a lower lock-hopper, (ii) purging the lock-hoppers with purging gas, and (iii) filling the reaction chamber containing a descending moving bed from the upper lock-hopper and/or emptying the reaction chamber into the lower lock-hopper. The pressure equalization between the reaction chamber and lock-hopper is achieved with product gas. The method then involves: (iv) optionally, relieving the lock-hoppers and conveying the product gas flow into the product line, and (v) purging the lock-hoppers with purging gas.
