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 as its catalytically active component a hydrotalcite-type material having in its uncalcined state the general formula EQU Me'(II).sub.z Me(II).sub.x Me(III).sub.y (CO.sub.3)(OH).sub.2(x+z)+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 platinum, palladium, silver, ruthenium and iridium; PA0 ME(II) is at least one divalent metal selected from the Group comprising copper, cobalt, magnesium, manganese, nickel and zinc; PA0 ME(III) is at least one trivalent metal selected from the Group comprising aluminum, chromium and iron; and PA0 x, y and z are positive numbers satisfying the following relationships: EQU (x+z)/y.gtoreq.0.5; EQU 0<z/y.ltoreq. 3; and EQU x.gtoreq.0.
