摘要： A process can be used for the treatment of an offgas stream, which is formed in a plant for the production of aluminum by electrolytic reduction of aluminum oxide in a melt, using at least one anode composed of a carbon-containing material. The offgas stream contains carbon oxides due to the reduction of the aluminum oxide by the carbon. At least a substream of the carbon oxides contained in the offgas stream is reacted with hydrogen or mixed with a hydrogen stream and is subsequently passed to a use. After purification and conditioning of the offgas stream in a device, an enrichment, for example with carbon monoxide, can subsequently be carried out in a reactor and the synthesis gas obtained in this way can be fed to a chemical or biotechnological plant for the synthesis of chemicals of value.

摘要： A process can be used for performing a pyrolysis of hydrocarbons in a rotary drum reactor at a temperature in the range of from 600 to 1800° C. The heat for the endothermic pyrolysis is provided by resistive heating of at least one particulate electrically conductive material introduced into said rotary drum reactor and moved through the rotary drum reactor with a flow of a hydrocarbon. The rotary drum reactor contains (A) an inner wall made of electrically insulated material, (B) a pressure-bearing outer wall, and (C) an electrical heating system attached to the inner wall and/or at least one integrated electrically conducting electrode pair. The at least one electrode pair is located at both ends of the inner wall of the rotary drum.

摘要： A method of continuously performing one or more heat-consuming processes, where at least one heat-consuming process is electrically heated. The maximum temperature in the reaction zone of the heat-consuming process is higher than 500° C., at least 70% of products of the heat-consuming process are continuously processed further downstream and/or fed to a local energy carrier network, and the electrical energy required for the heat-consuming process is drawn from an external power grid and from at least one local power source. The local power source is fed by at least one local energy carrier network and by products from the heat-consuming process. The local energy carrier network stores natural gas, naphtha, hydrogen, synthesis gas, and/or steam as energy carrier, and has a total capacity of at least 5 GWh. The local energy carrier network is fed with at least one further product and/or by-product from at least one further chemical process.
