A catalyst system comprising a first solid material comprising a silicoaluminophosphate and a second solid material comprising a zeolite and a compound containing zinc and a metal selected from the group consisting of Group IIIA and Group VIB, and a method of preparing such catalyst system, are disclosed. The thus-obtained catalyst system is employed as a catalyst in the conversion of at least a portion of a hydrocarbon feedstock comprising oxygenated hydrocarbons to aromatics (BTX), and, in particular, xylenes. In an alternate embodiment, a hydrocarbon feedstock comprising oxygenated hydrocarbons are converted to aromatics by sequentially contacting the hydrocarbon feedstock with the first solid material and then the second solid material.
