    Abstract: 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.

    IPC: C07C7/163

    Abstract: The invention relates to a process for removing dienes from a material stream comprising C3 to C5 hydrocarbons by selective hydrogenation at a specified reaction pressure and a specified reaction temperature in the presence of a hydrogenation catalyst, wherein the reaction pressure and the reaction temperature at the reactor inlet are regulated such that the reaction pressure at the reactor inlet does not deviate by more than 0.01 bar from the specified reaction pressure and the reaction temperature at the reactor inlet does not deviate by more than 0.1° C. from the specified reaction temperature and the proportion of hydrogen supplied to the selective hydrogenation is in the range from 2 to 20 moles per mole of diene present in the material stream comprising C3 to C5 hydrocarbons.
