Abstract
A process for preparing aromatic compounds, wherein a gaseous feed containing C.sub.6 to C.sub.20 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 EQU Me(II).sub.x Me(III).sub.y (CO.sub.3)(OH).sub.2x+3y-2 . aq with an x-ray diffraction (d003) greater than about 7.4 Angstroms, and wherein PA0 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; PA0 Me(III) is at least one trivalent metal selected from the group comprising aluminum, chromium and iron; and PA0 x and y are positive numbers satisfying the following relationship x/y.gtoreq.0.5.
