1. A catalyst composition comprising:
(a) a porous alumina-silicate zeolite selected from the group consisting of Faujasite (FAU), Zeolite Mobil type Five (MFI), Zeolite Kerr Five (KFI) and Zeolite Beta polymorph A (BEA) as catalyst support;
(b) a first metal selected from transition metals of group VIB, wherein the amount of the first metal is from 1 wt % to 10 wt % based on the porous alumina-silicate zeolite;
(c) a second metal selected from metals of group IIIA or IVA, wherein the amount of the second metal is from 1 wt % to 8 wt % based on the porous alumina-silicate zeolite; and
(d) an alkali metal, wherein the amount of alkali metal is from 0.5 wt % to 2 wt % based on the porous alumina-silicate zeolite,
wherein the catalyst composition is free of noble metal.
