The invention relates to a catalyst composition comprising a) a carrier comprising: (i) of from 5 to 95 wt % of CON type zeolite, (ii) of from 5 to 95 wt % of ZSM-5 type zeolite; and (iii) of from 10 to 60 wt % of inorganic binder; and b) of from 0.001 to 10 wt % one or more metals selected from the group consisting of Group 6-11 of the IUPAC Periodic Table of Elements. The invention further relates to a process for preparing the catalyst composition and to a process for the conversion of an alkylaromatic hydrocarbons containing feedstock using a catalyst prepared by the present process.
