A reactor for carrying out an endothermic reaction, in particular a high-temperature reaction, in which a product gas is obtained from a feed gas, wherein: the reactor surrounds a reactor interior; the reactor is configured to provide a reactor bed in a reaction zone of the reactor interior, which reactor bed comprises a large number of solid material particles; the reactor is also configured to guide the feed gas into the reaction zone; in order to heat the feed gas, the reactor is designed to heat the solid material particles in the reaction zone such that, by transferring heat from the solid material particles to the feed gas, the feed gas in the reaction zone can be heated to a reaction temperature in order to participate as a starting product in the endothermic reaction for producing the product gas.

Reactor for endothermic high-temperature reactions

A blend composition including a mixture of (i) petroleum coke in a content of 20 to 99 weight-%; and (ii) pyrolytic carbon in a content of 1 to 80 weight-%, in view of the total weight of the blend composition, wherein the blend composition contains at least two particle size fractions: (i) granular above 0.5 mm and (ii) fines below 0.5 mm, and wherein pyrolytic carbon is at least present in the granular size fraction, an electrode recipe, and the use of the electrode as an anode in a process of making aluminum.

Blend composition comprising petroleum coke and pyrolytic carbon for electrodes

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.

Process and integrated plant for the treatment of the carbon oxides formed in the production of aluminum

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.

Electrically heated, hybrid high-temperature method

The invention relates to a process for producing hydrogen, carbon monoxide and a carbon-containing product in at least one reaction apparatus, wherein the at least one reaction apparatus comprises a bed of carbon-containing material and is characterized in that the bed of carbon-containing material in the at least one reaction apparatus is alternately heated to a temperature of >800° C. and, no later than upon reaching a temperature of 1800° C., cooled to a maximum of 800° C., wherein hydrogen and carbon monoxide are produced during the heating phase and carbon and hydrogen are produced during the cooling phase.

Process and device for producing hydrogen, carbon monoxide and a carbon-containing product

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.
