    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.

    摘要: A process can utilize carbon oxides formed in the production of aluminum, by electrolytic reduction of aluminum oxide in a melt using at least one anode made of a carbon-comprising material. A pyrolysis of hydrocarbons, in particular methane or natural gas, is carried out in which pyrolysis carbon and hydrogen are formed. The pyrolysis carbon is used for the production of the at least one anode. The hydrogen formed in the pyrolysis of methane is mixed with carbon dioxide and/or carbon monoxide from the electrolytic production of aluminum, to produce a gas stream which is parsed to a further use. An integrated plant contains an electrolysis apparatus for producing aluminum by melt-electrolytic reduction of aluminum oxide, and also contains at least one reactor in which pyrolysis carbon and hydrogen are produced by pyrolysis of hydrocarbons.

    摘要: The invention relates to a process for producing synthesis gas (5) in which hydrocarbon (2) is decomposed thermally in a first reaction zone (11) to hydrogen and carbon, and hydrogen formed is passed from the first reaction zone (Z1) into a second action zone (Z2) in order to be reacted therein with carbon dioxide (4) to give water and carbon monoxide. The characteristic feature here is that energy required for the thermal decomposition of the hydrocarbon is supplied to the first reaction zone (Z1) from the second reaction zone (Z2).
