摘要: The invention relates to a process for producing synthesis gas, in which carbon and hydrogen are obtained from hydrocarbon by thermal decomposition. At least a portion of the carbon obtained by the thermal decomposition is reacted, and at least a portion of the hydrogen obtained is reacted with carbon dioxide by a reverse water-gas shift reaction to give carbon monoxide and water. Carbon obtained by the thermal hydrocarbon decomposition is used as fuel in a power plant operation wherein the carbon is combusted to produce electrical power, and carbon dioxide formed in the combustion of the carbon is used in the reverse water-gas shift reaction.

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: An integrated process contains the following steps of: (i) pyrolysis of hydrocarbons to carbon and hydrogen, (iia) removal of at least a part of the produced carbon in step (i) and at least partly further processing of said carbon into a carbon containing electrode, and (iib) removal of the hydrogen produced in step (i) and at least partly using said hydrogen for providing energy, preferably electric energy or heat, for the electrode production in step (iia). A joint plant is also useful, which contains (a) at least one reactor for a pyrolysis process, (b) at least one reactor for the production of electrodes for an aluminum process, (c) a power plant and/or at least one gas-fired burner, and optionally, (d) at least one reactor for the electrolysis for producing aluminum.

摘要: The invention relates to a method of carrying out heat-consuming processes, wherein the total energy required averaged over a year for the heat-consuming process originates from at least two different energy sources, where one of the energy sources is an electric energy source whose power varies in the range from 0 to 100% of the total power required, and three different energy modes can individually provide the total power required for the heat-consuming process: (i) exclusively electric energy, (ii) a mixture of electric energy and at least one further nonelectric energy source or (iii) exclusively nonelectric energy, where the changeover time in which the change from one energy mode to another energy mode is completed is not more than 30 minutes.

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: 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).
