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.

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.

A method for producing synthesis gas may involve introducing a hydrocarbon-containing coke-oven gas and a carbon dioxide-containing converter gas into a first reaction zone where hydrogen present in the hydrocarbon-containing coke-oven gas reacts at least partly with carbon dioxide to form water, which reacts thermally with hydrocarbon to form synthesis gas containing carbon monoxide and hydrogen. The method may further involve introducing an oxygen-containing gas in a second reaction zone, and using the oxygen-containing gas and some hydrogen from the first reaction zone to produce thermal energy. Still further, the method may involve supplying the thermal energy produced in the second reaction zone to the first reaction zone.
