Abstract: The invention relates to a catalyst for the dehydroaromatisation of C
1 -C
4 -aliphates, that can be obtained by the double treatment of a zeolith from the groups MFI and MWW with mixtures containing NH
4 , respectively with subsequent drying and calcining. The catalyst contains molybdenum and optionally, Cu, Ni, Fe, Co, Mn, Cr, Nb, Ta, Zr, V, Zn and/or Ga as additional elements. The invention also relates to a method for the dehydroaromatisation of a mixture containing C
1 -C
4 -aliphates by reacting in the presence of a catalyst.
