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 as its catalytically active component a hydrotalcite-type material having in its uncalcined state the general formula Me'(II)zMe(II)xMe(III)y(CO3)(OH)2(x+z)+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 platinum, palladium, silver, ruthenium and iridium; ME(II) is at least one divalent metal selected from the Group comprising copper, cobalt, magnesium, manganese, nickel and zinc; ME(III) is at least one trivalent metal selected from the Group comprising aluminum, chromium and iron; and x, y and z are positive numbers satisfying the following relationships: (x+z)/y>=0.5; 0<z/y<= 3; and x>=0.
