Abstract
A method () is proposed for the manufacture of benzene, in which a first feedstock mixture is formed, which contains alkylated aromatics and hydrogen, and in which the alkylated aromatics contained in the first feedstock mixture are partially converted with the hydrogen contained in the first feedstock mixture to the benzene through hydrodealkylation (), thereby obtaining a first product mixture, wherein the first product mixture contains the benzene, the unconverted alkylated aromatics, alkanes with one to three carbon atoms formed in the conversion of the alkylated aromatics to the benzene, and the unconverted hydrogen, and wherein at least a part of the alkanes with one to three carbon atoms and of the hydrogen are separated from the first product mixture, thereby obtaining a light-gas fraction. It is proposed that the hydrogen contained in the first feedstock mixture is provided at least in part with the use of a low-temperature separation (), to which at least a part of a second product mixture is supplied, wherein the second product mixture is formed at least in part through steam cracking () of a second feedstock mixture, and that the light-gas fraction is also supplied at least in part to the low-temperature separation (). A corresponding plant also forms the subject matter of the invention.
