| 摘要 | The invention relates to a method for producing aromatic hydrocarbons from a C 1 -C 4 alkane or a mixture of C 1 -C 4 alkanes. Said method is characterized in that a) an educt flow A containing a C 1 -C 4 alkane or a mixture of C 1 -C 4 alkanes is brought in contact with a catalyst, and some of the C 1 -C 4 alkane or some of the mixture of C 1 -C 4 alkanes is reacted to aromatic hydrocarbon/s, b) the product flow B resulting from step a) is separated into a low-boiling flow C containing the main portion of the hydrogen and the non-reacted C 1 -C 4 alkane or mixture of C 1 -C 4 alkanes, and a high-boiling flow D or several high-boiling flows D' containing the main portion of the obtained aromatic hydrocarbon, and c) the low-boiling flow C is fed to another process consuming C 1 -C 4 alkane, the hydrogen contained in the low-boiling flow C being optionally eliminated beforehand. | ||||||
