Abstract: 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.

Abstract: A blend composition contains a mixture of petroleum coke and pyrolytic carbon. An electrode recipe, and the use of this electrode as an anode in the process of producing aluminum are described.

Abstract: Vessels selected from crucibles, pans, open cups and saggars essentially comprising of two components, from which (A) one component being a ceramic matrix composite, and (B) the second component being from metal or alloy, and wherein component (A) is the inner one.
