Verfahren und Katalysator zur Herstellung aromatischer Verbindungen

摘要

A process for preparing aromatic compounds, wherein a gaseous feed containing C6 to C20 hydrocarbons is reacted in the presence of a catalyst, which catalyst comprises a metal from Group VIII of the Periodic Table loaded on a hydrotalcite-type support material having in its uncalcined state the general formula Me(II)xMe(III)y(CO3)(OH)2x+3y-2 . aq with an x-ray diffraction (d003) greater than about 7.4 Angstroms, and wherein Me(II) is at least one divalent metal selected from the group comprising copper, magnesium, manganese, zinc and a metal from Group VIII of the Periodic Table; Me(III) is at least one trivalent metal selected from the group comprising aluminum, chromium and iron; and x and y are positive numbers satisfying the following relationship x/y >/= 0.5.
