摘要： 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.

摘要： 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 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.

摘要： A process for producing acetylene and syngas by partial oxidation of hydrocarbons with oxygen, involving: separately preheating a hydrocarbon and a oxygen-comprising input stream; mixing in a mass flow ratio of the oxygen-comprising to hydrocarbon stream at an oxygen number no more than 0.31; feeding the streams via a burner block to a combustion chamber and therein partially oxidizing the hydrocarbon(s) to a cracking gas; quenching the cracking gas to 80 to 90° C. downstream by injecting an aqueous quench medium to obtain a process water stream-1 and a product gas stream-2; cooling the product gas stream-2 in a cooling column by direct heat exchange with cooling water to obtain a process water stream-2 as bottoms, a product gas stream-2 as uppers, and a sidestream; and depleting the sidestream of soot in an electrofilter to generate therein a process water stream-3 combined with water streams-1/2 to afford the process water stream-4.
